AD5621AKSZ-REEL7

2.7 V to 5.5 V, <100 μA, 8-/10-/12-Bit  nanoDAC, SPI Interface in LFCSP and SC70

数模转换器- DAC SGL 2.7-5.5V 12Bit

GENERAL DESCRIPTION  AD5621AKSZ-REEL7

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 railto-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.
