Excalbur Low-Noise High-Speed Precision Op Amps

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 10.5 nV/Hz with a 10-Hz 1/f corner and symmetrical 40-V/??s 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 340ns to 0.1% of a 10-V step with a 2-k/100-pF load is useful in fast actuator/positioning drivers. Under similar test conditions, settling time to 0.01% is 400 ns. The devices are 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 TLE214x and TLE214xA are useful for low-droop sample-and-holds and direct buffering of long cables, including 4-mA to 20-mA current loops. The special design also exhibits an improved insensitivity to inherent integrated circuit component mismatches as is evidenced by a 500-??V maximum offset voltage and 1.7-??V/C typical drift. Minimum common-mode rejection ratio and supply-voltage rejection ratio are 85 dB and 90 dB, respectively. Device performance is relatively independent of supply voltage over the 2-V to 22-V range. Inputs CAN operate between VCC 0.3 to VCC+ 1.8 V without inducing phase reversal, although excessive input current may flow out of each input exceeding the lower common-mode input range. The all-npn output stage provides a nearly Rail-to-Rail output swing of VCC 0.1 to VCC+ 1 V under light current-loading conditions. The device CAN sustain shorts to either supply since output current is internally limited, but care must be taken to ensure that maximum package power dissipation is not exceeded. 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 200 ns. 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 0C to 70C, I-suffix devices from 40C to 105C, and M-suffix devices over the full military temperature range of 55C to 125C.
