The AD5641, a member of the nanoDACВ® family, is a single,
14-bit, buffered, voltage-out DAC that operates from a single
2.7 V to 5.5 V supply, typically consuming 75 ВµA at 5 V. The
part comes in tiny LFCSP and SC70 packages. Its on-chip
precision output amplifier allows rail-to-rail output swing to be
achieved. The AD5641 uses a versatile 3-wire serial interface
that operates at clock rates up to 30 MHz and is compatible with
SPIВ®, QSPIв„ў, MICROWIREв„ў, and DSP interface standards. The …
