GENERAL DESCRIPTION
The AD5302/AD5312/AD5322 are dual 8-, 10-, and 12-bit buffered voltage output DACs in a 10-lead MSOP that 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 AD5302/AD5312/AD5322 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.
