TLE2142ID (TEXAS INSTRUMENTS)

The TLE2142ID is a Dual Low-noise High-speed Precision Operational Amplifier built using complementary bipolar Excalibur process. The design incorporates an input stage that simultaneously achieves low audio-band noise of 10.5nV/R/100pF load is useful in fast actuator/positioning drivers. Under similar test conditions, settling time to 0.01% is 400ns. The op amp is stable with capacitive loads up to 10nF, although the 6MHz bandwidth decreases to 1.8MHz at this high loading level. As such, it 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 85dB and 90dB, respectively. Differential inputs of VCC± can be maintained without damage to the device.
