MCP47CMD21中文资料12-Bit Single Output DAC w/MTP and I2C™数据手册Microchip规格书

描述 Description

MCP47CMD21 is a single channel, 12-bit, buffered voltage output Digital-to-Analog Converter (DAC) with MTP memory and an I²C 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 a fast settling time of 4 µs. This device has integrated MTP memory that can be written up to 32 times, for each specific register. It is suitable for consumer and industrial applications, such as set point or offset trimming, sensor calibrations, motor control applications and more.
