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, combined with a 4.7-MHz bandwidth, 2.5-V/µs 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 µV within the first 300 ms of operation. The offset is then digitally stored in an integrated successive approximation register (SAR). Immediately
The TLC4501, TLC4501A, TLC4502 and TLC4502A are precision CMOS single‑supply rail‑to‑rail operational amplifiers with self‑calibrating circuitry that trims input offset voltage to less than 40 µV within 300 ms. They offer a 4.7 MHz gain‑bandwidth product, 2.5 V/µs slew rate, and up to 50 mA output drive, suitable for data‑acquisition, measurement equipment, industrial control, and portable digital scales.
