Automotive Dual Low-Noise High-Speed Precision Operational Amplifier

The TLE2142-Q1 device is a

high-performance, internally compensated operational amplifier built using the Texas

Instruments complementary bipolar Excalibur™ process. The

device is a pin-compatible upgrade to standard industry products.

The design incorporates an input stage

that simultaneously achieves low audio-band noise of 10.5nV/√

Hz with a 10Hz1/f corner and symmetrical 40V/µs slew rate

typically with loads up to 800pF. The resulting low distortion and high power

bandwidth are important in high-fidelity audio applications. A fast settling time of

430ns to 0.1% of a 10V step with a 2kΩ/100pF load is useful in fast

actuator/positioning drivers. Under similar test conditions, settling time to 0.01%

is 640ns.
