What the HT872 family does
The HT8721/HT8722/HT8724 are precision CMOS operational amplifiers available in single, dual, and quad channel configurations. These rail-to-rail input/output devices operate on a 2.7 V to 5.5 V single supply and feature an 8.2 MHz gain bandwidth product, 5.2 V/µs slew rate, and 500 µV maximum offset voltage. Engineers utilize them for audio amplification, current sensing, barcode scanners, and multi-pole filters. Their low input bias current and high speed make them ideal for buffering CMOS ADCs and DACs in portable instruments and cellular power amplifier control circuits.
