Product Summary

The AD390TD/883B is a quad 12-bit microprocessor which contains four 12-bit high speed voltage-output digital-to-analog converters in a compact 28-pin hybrid package. The AD390TD/883Bis based on a proprietary latched 12-bit DAC chip which reduces chip count and provides high reliability. The AD390TD/883B is ideal for systems requiring digital control of many analog voltages where board space is at a premium.
