These devices utilize the IN Texas Instruments silicon gate LinCMOS process, giving them stable input-offset voltages that are available in selected grades of 2, 5, or 10 m maximum, very high input impedances, and extremely low input offset and bias currents. Because the input common-mode range extends the negative rail and the power consumption is extremely low, this series is ideally suited for battery-powered or energy-conserving applications. The series offers operation down a 1.4- supply, is stable at unity gain, and has excellent noise characteristics. These devices have internal electrostatic-discharge (ESD) protection circuits that prevent catastrophic failures at voltages up 2000 as tested under MIL-STD-883C, Method 3015.1. However, care should be exercised in handling these devices as exposure ESD may result in degradation of the device parametric performance. Because of the extremely high input impedance and low input bias and offset currents, applications for these devices include many areas that have previously been limited BIFET and NFET product types. Any circuit using high-impedance elements and requiring small offset errors is a good candidate for cost-effective use of these devices. Many features associated with bipolar technology are available with LinCMOS operational amplifiers without the power penalties of traditional bipolar devices.

PARAMETER MEASUREMENT INFORMATION single-supply versus split-supply test circuits Because the TLC25_4, TLC25_4A, and TLC25_4B are optimized for single-supply operation, circuit configurations used for the various tests often present some inconvenience since the input signal, in many cases, must be offset from ground. This inconvenience can be avoided by testing the device with split supplies and the output load tied the negative rail. A comparison of single-supply versus split-supply test circuits is shown below. The use of either circuit gives the same result. DD DD + I + O I + O CL RL CL RL (a) SINGLE-SUPPLY DD (b) SPLIT-SUPPLY Figure 1.

APPLICATION INFORMATION latch-up avoidance Junction-isolated CMOS circuits have an inherent parasitic PNPN structure that can function as an SCR. Under certain conditions, this SCR may be triggered in a low-impedance state, resulting in excessive supply current. To avoid such conditions, no voltage greater than 0.3 beyond the supply rails should be applied any pin. In general, the operational amplifiers supplies should be established simultaneously with, or before, application of any input signals. output stage considerations The amplifier s output stage consists of a source-follower-connected pullup transisr and an open-drain pulldown transisr. The high-level output voltage ( OH ) is virtually independent of the I DD selection and increases with higher values of DD and reduced output loading. The low-level output voltage ( OL ) decreases with reduced output current and higher input common-mode voltage. With no load, OL is essentially equal the potential of DD /GND. supply configurations Even though the TLC25_4C series is are characterized for single-supply operation, they can be used effectively in a split-supply configuration if the input common-mode voltage ( ICR ), output swing ( OL and OH ), and supply voltage limits are not exceeded. circuit layout precautions Whenever extremely high circuit impedances are used, care must be exercised in layout, construction, board cleanliness, and supply filtering avoid hum and noise pickup as well as excessive dc leakages.
