MCP48CVD12数据手册集成电路（IC）的数模转换器（DAC）规格书PDF

描述 Description

MCP48CVD12 is a dual channel, 10-bit, buffered voltage output Digital-to-Analog Converter (DAC) with volatile memory and a SPI Compatible Serial Interface. This device provides four different voltage reference options: device VDD, external VREF (Buffered or unbuffered) and internal bandgap. It offers .25 LSB Integral Non-Linearity (INL) with low power consumption and a fast settling time of 4 µs. It is suitable for consumer and industrial applications, such as set point or offset trimming, sensor calibrations, motor control applications and more.



For different resolutions and number of output channels, please check out our other parts in the MCP48CVDxx family.
