The TLE2142CDG4 is a dual low-noise high-speed high-performance internally compensated Operational Amplifier built using Texas Instruments complementary bipolar Excalibur process. The design incorporates an input stage that simultaneously achieves low audio-band noise of 10.5nV//100pF load is useful in fast actuator/positioning drivers. Under similar test conditions, settling time to 0.01% is 400ns. The device is stable with capacitive loads up to 10nF, although the 6MHz bandwidth decreases to 1.8MHz at this high loading level. As such, the TLE214x is useful for low-droop sample-and-holds and direct buffering of long cables, including 4 to 20mA current loops. The special design also exhibits an improved insensitivity to inherent integrated circuit component mismatches as is evidenced by a 500μV maximum offset voltage and 1.7μV/°C typical drift. Minimum common-mode rejection ratio and supply-voltage rejection ratio are 85 and 90dB, respectively.
