GENERAL DESCRIPTION
The AD5601/AD5611/AD5621, members of the nanoDAC® family, are single, 8-/10-/12-bit, buffered voltage output DACs that operate from a single 2.7 V to 5.5 V supply, consuming typically 75 μA at 5 V. The parts come in tiny LFCSP and SC70 packages. Their on-chip precision output amplifier allows rail to-rail output swing to be achieved. The AD5601/AD5611/ AD5621 utilize a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and is compatible with SPI, QSPI™, MICROWIRE™, and DSP interface standards.
