HT2348ARTZ8

HT1348, HT2348, and HT4348 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. Devices such as filters, integrators, diode amplifiers, shunt sensors, and high-impedance sensors can all benefit from this combination of features. Wide bandwidth and low distortion characteristics benefit audio and other AC applications. For most cost-sensitive applications, the C grade offers the same AC performance at a lower price point, but 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.
