The TLC4501 and TLC4502 are the highest precision CMOS single supply rail-to-rail operational amplifiers available today. The input offset voltage is 10uV typical and 100uV maximum. This exceptional precision, combined with a 4.7MHz bandwidth, 2.5V/us slew rate, and 50mA 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 100uV within the first 300ms 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.
