Description

MCP48CVB08 is a octal channel, 8-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 4µs. It is suitable for consumer and industrial applications, such as set point or offset trimming, sensor calibrations and motor control applications. For different resolutions and number of output channels, please check out our other parts in the MCP48CVBxx family.
