AD53037JST

GENERAL DESCRIPTION

The AD5303/AD5313/AD5323 are dual 8-, 10- and 12-bit buffered voltage output DACs in a 16-lead TSSOP package tha operate from a single +2.5 V to +5.5 V supply consuming 230 µA at 3 V. Their on-chip output amplifiers allow the outputs to swing rail-to-rail with a slew rate of 0.7 V/µs. The AD5303/AD5313/AD5323 utilize a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and is compatible with standard SPI™, QSPI, MICROWIRE™ and DSP interface standards
