12/10/8-Bit Low Power Single DAC With Serial Interface and Voltage Output
FEATURES 12/10/8-Bit Single DAC in 08 Lead MSOP Package Ultra-Low Power Consumption Guaranteed Monotonic Wide Voltage Output Swing Buffer Three-wire SPI/QSP and Microwire Interface Compatible Three Software-Selectable Power-Down Output Impedances (1 K Ohm, 100 K Ohm and Hi-Z) Schmitt-Triggered Inputs for Direct Interfacing to Opto-couplers APPLICATION Battery-Powered Applications Industrial Process Control Digital Gain and Offset Adjustment BLOCK DIAGRAM
OVERVIEW The ICM7561, ICM7541 and ICM7521 are 12-Bit, 10-Bit and 8-Bit Voltage Output, Low Power, Single DACs respectively, with guaranteed monotonic behavior. These DACs are available in 8 Lead MSOP package. They have three Software-Selectable Power-Down Output Impedances (1 K Ohm, 100 K Ohm and Hi-Z) as additional safety feature for applications that drive transducers or valves. The operating supply range is 2.7V to 5.5V. The input interface is an easy to use three-wire SPI, QSPI and Microwire compatible interface. The DAC has SchmittTriggered Inputs for Direct Interfacing to Opto-couplers easily.
