The AD5302 are dual 8-bit buffered voltage output DACs in a 10-lead mSOIC package that operate from a single +2.5 V to +5.5 V supply consuming 230 mA at 3 V. Their on-chip output amplifiers allow the outputs to swing rail-to-rail with a slew rate of 0.7 V/ms. The AD5302 utilize a versatile 3-wire serial interface which operates at clock rates up to 30 MHz and is compatible with standard SPI^™, QSPI^™, MICROWIRE^™ and DSP interface standards.
