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
V typical and 40 V maximum. This exceptional precision,
combined with a 4.7-MHz bandwidth, 2.5-V/
s slew rate, and 50-mA 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
V
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.
