The TLE2142 device is a high-performance, internally compensated operational amplifier built using the Texas
Instruments complementary bipolar Excaliburв„ў process. It is a pin-compatible upgrade to standard industry
products.
The design incorporates an input stage that simultaneously achieves low audio-band noise of 10.5 nV/в€љHz with a
10-Hz 1/f corner and symmetrical 40-V/Вµs 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-kΩ/100-pF load is useful in fast actuator/positioning drivers. Under similar test conditions,
settling time to 0.01% is 400 ns.
The device is 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 is useful for low-droop sample-and-holds and direct buffering of …
