Beschreibung von TLE2142
The TLE214x and TLE214xA devices are high-performance, internally compensated operational amplifiers built using Texas Instruments complementary bipolar Excalibur process. The TLE214xA is a tighter offset voltage grade of the TLE214x. Both are pin-compatible upgrades to standard industry products.
The design incorporates an input stage that simultaneously achieves low audio-band noise of 10.5nV/√ Hz with a 10Hz 1/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.
Both versions can also be used as comparators. Differential inputs of VCC± can be maintained without damage to the device. Open-loop propagation delay with TTL supply levels is typically 200ns. This gives a good indication as to output stage saturation recovery when the device is driven beyond the limits of recommended output swing.
Both the TLE214x and TLE214xA are available in a wide variety of packages, including both the industry-standard 8-pin small-outline version and chip form for high-density system applications. The C-suffix devices are characterized for operation from 0°C to 70°C, I-suffix devices from −40°C to 105°C, and M-suffix devices over the full military temperature range of −55°C to 125°C.
