The AD87 provides exceptional common-mode rejection ratio (8 db) and high bandwidth while amplifying signals well beyond the supply rails. The on-chip resistors are laser-trimmed for excellent gain accuracy and high commonmode rejection ratio. They also have outstanding gain temperature coefficient. The amplifier s common-mode range extends to almost double the supply voltage, making it ideal for single-supply applications that require a high common-mode voltage range.

Table. Thermal Resistance Package Type θja Unit 8-Lead MSOP 3 C/W 8-Lead SOIC C/W MAXIMUM POWER DISSIPATION The maximum safe power dissipation for the AD87 is limited by the associated rise in junction temperature (TJ) on the die. At approximately C, which is the glass transition temperature, the properties of the plastic change. Even temporarily exceeding this temperature limit may change the stresses that the package exerts on the die, permanently shifting the parametric performance of the amplifiers. Exceeding a temperature of C for an extended period may result in a loss of functionality.

Maximum Power Dissipation vs. Ambient Temperature SHORT-CIRCUIT CURRENT The AD87 has built-in, short-circuit protection that limits the output current (see Figure 3 for more information). While the short-circuit condition itself does not damage the part, the heat generated by the condition can cause the part to exceed its maximum junction temperature, with corresponding negative effects on reliability. Figure and Figure 3, combined with knowledge of the part s supply voltages and ambient temperature, can be used to determine whether a short circuit will cause the part to exceed its maximum junction temperature. 79- ESD CAUTION Rev.

12 AD87 THEORY OF OPERATION +VS 7 kω kω IN SENSE kω kω IN+ 3 REF VS CIRCUIT INFORMATION AD87 Figure 3. Functional Block Diagram The AD87 consists of a low power, low noise op amp and four laser-trimmed on-chip resistors. These resistors can be externally connected to make a variety of amplifier configurations, including difference, noninverting, and inverting configurations. Taking advantage of the integrated resistors of the AD87 provides the designer with several benefits over a discrete design. DC Performance Much of the dc performance of op amp circuits depends on the accuracy of the surrounding resistors. This can be verified by a simple examination of the typical difference amplifier configuration, as shown in Figure 3. The output voltage is = R V ( IN + IN ) V V R3 as long as the following ratio of the resistors is tightly matched: R R = R R3 The resistors on the AD87 are laid out to optimize their matching, and they are laser trimmed and tested for their matching accuracy. Because of this trimming and testing, the AD87 can guarantee high accuracy and consistency for specifications such as gain drift, common-mode rejection, and gain error, even over a wide temperature range. AC Performance The feature size is much smaller in an IC than on a PCB, so the corresponding parasitics are also smaller, which helps the ac performance of the AD87. For example, the positive and negative input terminals of the AD87 op amp are not pinned out intentionally. By not connecting these nodes to the traces on the PCB, the capacitance remains low, resulting in both improved loop stability and common-mode rejection over frequency DRIVING THE AD87 With all configurations presenting at least several kilohms (kω) of input resistance, the AD87 is easy to drive. Drive the AD87 with a low impedance source: for example, another amplifier. The gain accuracy and common-mode rejection of the AD87 depend on the matching of its resistors. Even source resistance of a few ohms can have a substantial effect on these specifications. POWER SUPPLIES Use a stable dc voltage to power the AD87. Noise on the supply pins can adversely affect performance. Place a bypass capacitor of. μf between each supply pin and ground, as close as possible to each supply pin. Use a tantalum capacitor of μf between each supply and ground. It can be farther away from the supply pins and, typically, it can be shared by other precision integrated circuits. The AD87 is specified at ± V, but it can be used with unbalanced supplies, as well. For example, VS = V, +VS = V. The difference between the two supplies must be kept below 3 V. INPUT VOLTAGE RANGE The AD87 is able to measure input voltages beyond the rails because the internal resistors divide down the voltage before it reaches the internal op amp. Figure 3 shows an example of how the voltage division works in a difference amplifier configuration. In order for the AD87 to measure correctly, the input voltages at the input nodes of the internal op amp must stay within. V of the positive supply rail and can exceed the negative supply rail by. V. R R + R (V IN+ ) R3 R R V IN V IN+ R R + R (V IN+ ) Figure 3. Voltage Division in the Difference Amplifier Configuration For best long-term reliability of the part, voltages at any of the part s inputs (Pin, Pin, Pin 3, or Pin ) should stay within +VS V to VS + V. For example, on ± V supplies, input voltages should not exceed ±3 V. R 79-3 Rev. Page of
13 AD87 APPLICATIONS INFORMATION CONFIGURATIONS The AD87 can be configured in several ways; see Figure 38 to Figure. All of these configurations have excellent gain accuracy and gain drift because they rely on the internal matched resistors. Note that Figure 39 shows the AD87 as a difference amplifier with a midsupply reference voltage at the noninverting input. This allows the AD87 to be used as a level shifter. As with the other inputs, the reference must be driven with a low impedance source to maintain the internal resistor ratio. An example using the low power, low noise OP77 as a reference is shown in Figure 37. INCORRECT CORRECT kω kω 3 kω kω IN V = V IN Figure.

Difference Amplifier, Gain = V = V IN Figure. Noninverting Amplifier, Gain = DIFFERENTIAL PUT Certain systems require a differential signal for better performance, such as the inputs to differential analog-to-digital converters. Figure 3 shows how the AD87 can be used to convert a single-ended output from an AD8 instrumentation amplifier into a differential signal. The AD87 internal matched resistors at the inverting input maximize gain accuracy while generating a differential signal. The resistors at the noninverting input can be used as a divider to set and track the common-mode voltage accurately to midsupply, especially when running on a single supply or in an environment where the supply fluctuates. The resistors at the noninverting input can also be shorted and set to any appropriate bias voltage.

14 AD87 INSTRUMENTATION AMPLIFIER The AD87 can be used as a building block for a low power, low cost instrumentation amplifier. An instrumentation amplifier provides high impedance inputs and delivers high commonmode rejection. Combining the AD87 with an Analog Devices low power amplifier (examples provided in Table 7) creates a precise, power efficient voltage measurement solution suitable for power critical systems.

The AD87 difference amplifier cancels out common-mode errors from the input op amps, if they track each other. The differential gain accuracy of the in-amp is proportional to how well the input feedback resistors (RF) match each other. The CMRR of the in-amp increases as the differential gain is increased ( + RF/RG), but a higher gain also reduces the common-mode voltage range. Refer to A Designer s Guide to Instrumentation Amplifiers for more design ideas and considerations. CURRENT SOURCE The AD87 difference amplifier can be implemented as part of a voltage-to-current converter or a precision constant current source as shown in Figure. The internal resistors are tightly matched to minimize error and temperature drift. If the external resistors R and R are not well-matched, they will be a significant source of error in the system, so precision resistors are recommended to maintain performance. The ADR8 provides a precision voltage reference and integrated op amp that also reduces error in the signal chain. The AD87 has rail-to-rail output capability, which allows higher current outputs.
