description
The TLE2141M and TLE2141AM are high-performance, internally compensated operational amplifiers built
using Texas Instruments complementary bipolar Excalibur process. The TLE2141AM is a tighter offset voltage
grade of the TLE2141M. Both are pin-compatible upgrades to standard industry products.
The design incorporates a patent-pending input stage that simultaneously achieves low audio band noise of
10.5 nV/√Hz with a 10-Hz 1/f corner and symmetrical 40-V/µs 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.
