TLC4501概述

高级 LinEPIC 自校准 Self-Cal 精密单路运算放大器

The and TLC4502 are the highest precision CMOS single supply rail-to-rail operational amplifiers available today. The input offset voltage is 10 uV typical and 40 uV maximum. This exceptional precision, combined with a 4.7-MHz bandwidth, 2.5-V/us 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 uV 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.

Using this technology eliminates the need for noisy and expensive chopper techniques, laser trimming, and power hungry, split supply bipolar operational amplifiers.
