TLC4502 Datasheet | Texas Instruments

description The TLC4501 and TLC4502 are the highest precision CMOS single supply rail-to-rail operational amplifiers available today. The input offset voltage is 10 µV typical and 40 µV maximum. This exceptional precision, bined with a 4.7-MHz bandwidth, 2.5-V/µs slew rate, and 50-m A output drive, is ideal for multiple applications including: data acquisition systems, measurement equipment, industrial control applications, and portable digital scales. These amplifiers feature self-calibrating circuitry which digitally trims the input offset voltage to less than 40 µV within the first 300 ms of operation. The offset is then digitally stored in an integrated successive approximation register (SAR). Immediately after the data is stored, the calibration circuitry effectively drops out of the signal path, shuts down, and the device functions as a standard operational amplifier. 3 IN+ 2 IN- Offset Control + - Calibration Circuitry 8 VDD D/A 5V Power-On Reset Control Logic SAR A/D Oscillator 1 OUT 4 GND Figure 1.
