Excaliburâ ?? ¢低噪声高速精密运算放大器 Excalibur™ LOW-NOISE HIGH-SPEED PRECISION OPERATIONAL AMPLIFIERS

DESCRIPON

The TLE2141-Q1 device is a high-performance, internally compensated operational amplifier built using the Texas Instruments complementary bipolar Excalibur™ 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/√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.
