† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values, except differential voltages, are with respect to the midpoint between V_CC+ and V_CC.
2. Differential voltages are at IN+ with respect to IN . Excessive current will flow if input is brought below V_CC 0.3 V.
3. The output may be shorted to either supply. Temperature and/or supply voltages must be limited to ensure that the maximum dissipation rating is not exceeded.

The TLE2142 design incorporates a patent-pending input stage that simultaneously achieves low audio-band noise of 10.5 nV//Hz, with a 6-Hz 1/f corner and symmetrical 40-V/ms slew rate typically with loads up to 800 pF. The resulting low distortion and high power bandwidth are important in high-fidelity audio applications. A fast settling time of 340 ns to 0.1% of a 10-V step with a 2-kW/100-pF load is useful in fast actuator/positioning drivers. Under similar test conditions, settling time to 0.01% is 400 ns.

The devices are stable with capacitive loads up to 10 nF, although the 6-MHz bandwidth decreases to 1.8 MHz at this high loading level. As such, the TLE2142 and TLE2142A are useful for low-droop sample-and-holds and direct buffering of long cables, including 4-mA to 20-mA current loops.

The special design also exhibits an improved insensitivity to inherit integrated circuit component mismatches as is evidenced by a 750-mV maximum offset voltage and 1.7-mV/ typical drift. Minimum common-mode rejection ratio and supply voltage rejection ratio are 85 dB and 90 dB, respectively.

Device performance of TLE2142 is relatively independent of supply voltage over the ±2-V to ±22-V range. Inputs can operate between V_CC 0.3 to V_CC+ 1.8 V without inducing phase reversal, although excessive input current may flow out of each input exceeding the lower common-mode input range. The all-npn output stage provides a nearly rail-to-rail output swing of V_CC +0.1 to V_CC+ 1 V under light current-loading conditions. The TLE2142 can sustain shorts to either supply since output current is internally limited, but care must be taken to ensure that maximum package power dissipation is not exceeded.

Both versions can also be used as comparators. Differential inputs of V_CC± can be maintained without damage to the device. Open-loop propagation delay with TTL supply levels is typically 200 ns. This gives a good indication as to output stage saturation recovery when the device is driven beyond the limits of recommended output swing.

Both the TLE2142 and TLE2142A are available in a wide variety of packages, including both the industry-standard 8-pin small-outline version and chip form for high-density system applications. The C-suffix devices are characterized for operation from 0 to 70, I-suffix devices from 40 to 105, and M-suffix devices over the full military temperature range of 55 to 125.
