GENERAL DESCRIPTION
The AD53201 is a single, 12-bit buffered voltage out digital-toanalog converter (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 to be achieved. The AD5320 utilizes a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and is patible with standard SPI®, QSPI™, MICROWIRE™...
