com ICM7561/7541/7521 ICmic IC MICROSYSTEMS 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.
