HT8602ARZ

HT8601, HT8602, and HT8604 are single-channel, dual-channel, and quad-channel, rail-to-rail input and output, single-supply amplifiers featuring ultralow offset voltage and wide signal bandwidth. These amplifiers employ a novel patented trimming technique that achieves excellent performance without laser trimming. All devices operate from a 3 V to 5 V single supply. The combination of low offset, ultralow input bias current, and high-speed characteristics makes these amplifiers suitable for a wide range of applications. Filters, integrators, diode amplifiers, shunt sensors, and high-impedance sensors can all benefit from this combination of features. Wide bandwidth and low distortion make them ideal for audio and other AC applications. For most cost-sensitive applications, the D grade offers the same AC performance at a lower price point, with reduced DC accuracy. These amplifiers also feature rail-to-rail input and output swing capability, enabling designers to buffer CMOS ADCs, DACs, ASICs, and other wide-output-swing devices in single-supply systems.
