The AD1147 and AD1148 are 16-bit resolution, hybrid, latched input, digital-to-analog converters designed for microprocessor compatibility. They feature two 8-bit latched input DACs that allow direct offset and gain correction via a microprocessor interface. The devices utilize precision CMOS switches and laser-trimmed thin-film resistor networks to provide high accuracy and temperature stability.
