This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. THERMAL RESISTANCE θja is specified for the worst-case conditions, that is, θja is specified for the device soldered in the circuit board for surface-mount packages. Table 4. Package Type θja Unit 6-Lead LFCSP 9 C/W 8-Lead LFCSP 8 C/W Maximum Power Dissipation The maximum safe power dissipation for the ADA485-/ ADA485- is limited by the associated rise in junction temperature (TJ) on the die. At approximately 5 C, which is the glass transition temperature, the plastic changes its properties. Even temporarily exceeding this temperature limit may change the stresses that the package exerts on the die, permanently shifting the parametric performance of the ADA485-/ADA485-. Exceeding a junction temperature of 5 C for an extended period of time can result in changes in silicon devices, potentially causing degradation or loss of functionality. ADA485-/ADA485- The power dissipated in the package (PD) is the sum of the quiescent power dissipation and the power dissipated in the die due to the ADA485-/ADA485- drive at the output. The quiescent power is the voltage between the supply pins (VS) times the quiescent current (IS). PD = Quiescent Power + (Total Drive Power Load Power) P D = ( V I ) S S VS + V R OUT L V R OUT RMS output voltages should be considered. If RL is referenced to VS, as in single-supply operation, the total drive power is VS IOUT. If the rms signal levels are indeterminate, consider the worst case, when VOUT = VS/4 for RL to midsupply. P D = ( V I ) S S + ( V / 4) S R L In single-supply operation with RL referenced to VS, the worst case is VOUT = VS/. Airflow increases heat dissipation, effectively reducing θja. Also, more metal directly in contact with the package leads and exposed paddle from metal traces through holes, ground, and power planes reduce θja. Figure 4 shows the maximum safe power dissipation in the package vs. the ambient temperature for the LFCSP (9 C/W) package on a JEDEC standard 4-layer board. θja values are approximations.

12 ADA485-/ADA485- CIRCUIT DESCRIPTION The ADA485-/ADA485- feature a high slew rate input stage that is a true single-supply topology, capable of sensing signals at or below the negative supply rail. The rail-to-rail output stage can swing to within 8 mv of either supply rail when driving light loads and within.7 V when driving 5 Ω. High speed performance is maintained at supply voltages as low as.7 V. HEADROOM AND OVERDRIVE RECOVERY CONSIDERATIONS Input The ADA485-/ADA485- are designed for use in low voltage systems. To obtain optimum performance, it is useful to understand the behavior of the amplifier as input and output signals approach the amplifier s headroom limits. The input common-mode voltage range extends mv below the negative supply voltage or ground for single-supply operation to within. V of the positive supply voltage. Therefore, in a gain of +3, the ADA485-/ADA485- can provide full railto-rail output swing for supply voltage as low as 3.3 V, assuming the input signal swing is from VS (or ground) to. V. Exceeding the headroom limit is not a concern for any inverting gain on any supply voltage, as long as the reference voltage at the amplifier s positive input lies within the amplifier s input common-mode range. The input stage sets the headroom limit for signals when the amplifier is used in a gain of + for signals approaching the positive rail. For high speed signals, however, there are other considerations. Figure 38 shows 3 db bandwidth vs. dc input voltage for a unity-gain follower. As the common-mode voltage approaches the positive supply, the bandwidth begins to drop when within V of +VS. This can manifest itself in increased distortion or settling time. GAIN (db) G = + R L = kω V OUT =.V p-p V CM = 3V V CM = 3.V V CM = 3.V V CM = 3.3V 6. Figure 38. Unity-Gain Follower Bandwidth vs. Frequency for Various Input Common-Mode Higher frequency signals require more headroom than the lower frequencies to maintain distortion performance. Figure 39 illustrates how the rising edge settling time for the amplifier configured as a unity-gain follower stretches out as the top of a V step input approaches and exceeds the specified input common-mode voltage limit. OUTPUT VOLTAGE (V) G = + R L = kω V STEP = V TO 3V V STEP =.V TO 3.V V STEP =.V TO 3.V V STEP =.3V TO 3.3V V STEP =.4V TO 3.4V TIME (ns) Figure 39. Pulse Response, Input Headroom Limits The recovery time from input voltages. V or closer to the positive supply is approximately 5 ns, which is limited by the settling artifacts caused by transistors in the input stage coming out of saturation. The ADA485-/ADA485- do not exhibit phase reversal, even for input voltages beyond the voltage supply rails. Going more than.6 V beyond the power supplies turns on protection diodes at the input stage, which greatly increase the current draw of the devices. Output For signals approaching the negative supply and inverting gain, and high positive gain configurations, the headroom limit is the output stage. The ADA485-/ADA485- amplifiers use a common-emitter output stage. This output stage maximizes the available output range, limited by the saturation voltage of the output transistors. The saturation voltage increases with drive current, due to the output transistor collector resistance. As the saturation point of the output stage is approached, the output signal shows increasing amounts of compression and clipping. As in the input headroom case, higher frequency signals require a bit more headroom than the lower frequency signals. Output overload recovery is typically within 4 ns after the amplifier s input is brought to a nonoverloading value Rev. B Page of 6
13 ADA485-/ADA485- Figure 4 shows the output recovery transients for the amplifier recovering from a saturated output from the top and bottom supplies to a point at midsupply. INPUT AND OUTPUT VOLTAGE (V) INPUT VOLTAGE EDGES V OUT = +.5V TO V V OUT =.5V TO V TIME (ns) Figure 4. Overload Recovery G = R L = kω 53-4 OPERATING THE ADA485-/ADA485- ON BIPOLAR SUPPLIES The ADA485-/ADA485- can operate on bipolar supplies up to ±5 V. The only restriction is that the voltage between VS and the POWER DOWN pin must not exceed 6 V. Voltage differences greater than 6 V can cause permanent damage to the amplifier. For example, when operating on ±5 V supplies, the POWER DOWN pin must not exceed + V. POWER-DOWN PINS The ADA485-/ADA485- feature an ultralow power-down mode that lowers the supply current to less than 5 na. When a power-down pin is brought to within.6 V of the negative supply, the amplifier is powered down. Table 5 outlines the power-down pins functionality. To ensure proper operation, the power-down pins (PD, PD) should not be left floating. Table 5.
