Microchip Technology, Inc. Digital to Analog Converters (DAC) MCP48FEB12-E/UN

The MCP48FEB12-E/UN is a 12-bit Digital-to-Analog Converter (DAC) from Quarktwin Technology Ltd. It operates within a voltage range of 2.7V to 5.5V, with reduced specifications available from 1.8V to 2.7V. This DAC features a rail-to-rail output and a fast settling time of 7.8 ¬µs, making it suitable for applications requiring quick response times. The device supports multiple voltage reference options, including the device's VDD, an external VREF pin, or an internal band gap reference of 1.22V. It offers output gain options of unity (1x) or 2x, with the latter requiring the VREF pin voltage to be limited to a maximum of VDD/2. The MCP48FEB12-E/UN includes nonvolatile memory (EEPROM) for user-programmed settings, allowing for auto recall of saved DAC register settings and device configurations. Power consumption is low, with normal operation drawing less than 180 ¬µA and power-down mode consuming approximately 650 nA. The device features an SPI interface that supports write speeds up to 20 MHz and read speeds up to 10 MHz, making it compatible with low-voltage digital devices. The MCP48FEB12-E/UN is packaged in a 10-lead MSOP and is rated for an extended temperature range of -40¬8C to +125¬8C, suitable for various industrial applications.
