GENERAL DESCRIPTION

The AD53101 is a single, 10-bit, buffered voltage output DAC that operates from a single 2.7 V to 5.5 V supply, consuming 115 µA at 3 V. Its on-chip precision output amplifier allows rail-to-rail output swing. The AD5310 utilizes a versatile 3-wire serial interface that operates at clock rates of up to 30 MHz and is compatible with standard SPI™, QSPI™, MICROWIRE®, and DSP interface standards.
