MCP47CVB18T-20E/ST

Digital To Analog Converters Overview

The MCP47CVB18T-20E/ST is a single-channel, 10-bit buffered voltage output Digital-to-Analog Converter (DAC) from Microchip Technology. It features volatile memory and an I2C serial interface supporting Standard (100 kHz), Fast (400 kHz), and High-Speed (up to 3.4 MHz) modes. The device operates within a supply voltage range of 2.7V to 5.5V for full specifications, or 1.8V to 2.7V with reduced analog performance. Key electrical parameters include a typical settling time of 16 µs, a maximum Integral Nonlinearity (INL) of ±0.25 LSB, and a gain error of ±1% of Full Scale Range (FSR). It utilizes an R-2R resistor ladder architecture and includes Power-on/Brown-out Reset protection.
