| General Description

The ZJA3202 and ZJA3203 are rail-to-rail input and output, single-supply amplifiers featuring very low offset voltage, wide signal bandwidth, and low input voltage and current noise. The parts use a proprietary trimming technique that achieves superior precision without chopping glitches. The ZJA3202 and ZJA3203 are fully specified to operate from 2.7 V to 5 V single supply.

The combination of 5 MHz bandwidth, low offset, low noise, and low input bias current makes these amplifiers useful in a wide variety of applications. Filters, integrators, photodiode amplifiers, and high impedance sensors all benefit from the combination of these features. AC applications benefit from the wide bandwidth and low distortion.

Applications for the parts include portable and low power instrumentation, audio amplification for portable devicesand multi-pole filters. The ability to operate rail-to-rail both atthe input and at the output enables designers to buffer ADCs, DACs, ASICs, and other wide output swing devices in single-supply systems.

ZJA3202-1 and ZJA3203 are available in 5-lead SOT23 package. ZJA3202-2 is available in 8-lead narrow SOIC and 8-lead MSOP packages. ZJA3202-4 is available in 14-lead SOIC and 14-lead TSSOP packages. All of them are specified over the -40 °C to +125 °C extended industrial temperature range.
