Microchip Technology, Inc. Digital to Analog Converters (DAC) MCP48FVB14-20E/ST

The MCP48FVB14-20E/ST is a quad-channel, 10-bit Digital-to-Analog Converter (DAC) designed for applications requiring precise voltage output. It operates within a voltage range of 2.7V to 5.5V, with reduced specifications available at 1.8V to 2.7V. The device features a rail-to-rail output and a fast settling time of 7.8 ¬µs, making it suitable for dynamic applications. This DAC offers multiple voltage reference options, including the device's V_{DD}, an external V_{REF} pin, or an internal bandgap reference of 1.22V. It supports output gain configurations of 1x and 2x, depending on the reference source used. The MCP48FVB14-20E/ST includes nonvolatile memory options for user-programmable settings, allowing for automatic recall of DAC register settings and device configurations upon power-up. The device features a low-power consumption mode, drawing less than 2.6 mA during normal operation and only 680 nA in power-down mode. It utilizes an SPI interface that supports high-speed communication, with write speeds up to 20 MHz and read speeds up to 10 MHz. The operating temperature range is extended from -40¬8C to +125¬8C, making it suitable for a variety of industrial applications.
