8/10/12-Bit Dual Voltage Output Digital-to-Analog Converter
with SPI Interface
Features Description •
•
•
•
•
• The MCP4902/4912/4922 devices are dual 8-bit,
10-bit, and 12-bit buffered voltage output
Digital-to-Analog Converters (DACs), respectively. The
devices operate from a single 2.7V to 5.5V supply with
SPI compatible Serial Peripheral Interface. The user
can configure the full-scale range of the device to be
VREF or 2 * VREF by setting the Gain Selection Option
bit (gain of 1 of 2). •
