Description
AI
MCP48CVB22 is a dual channel, 12-bit, buffered voltage output Digital-to-Analog Converter (DAC) with volatile memory and an SPI Compatible Serial Interface. This device provides four different voltage reference options: device VDD, external VREF (Buffered or unbuffered) and internal bandgap. It offers 1 LSB Integral Non-Linearity (INL) with low power consumption and fast settling time of 16µs. It is suitable for consumer and industrial applications, such as set point or offset trimming, sensor calibrations and motor control applications.
