MCP4716A0T-E/CH

The MCP4716A0T-E/CH from Microchip Technology is a single-channel, 10-bit buffered voltage output Digital-to-Analog Converter (DAC) featuring nonvolatile memory and an I2C serial interface. This device supports a wide operating supply voltage range from 2.7V to 5.5V, making it suitable for various portable and low-power applications.

Key electrical specifications include a 10-bit resolution, a fast settling time of 6 µs typical, and rail-to-rail output. The DAC offers flexible voltage reference options, including VDD and an external VREF pin, with selectable output gain options of 1x or 2x when using the VREF pin. It also includes nonvolatile EEPROM memory for auto-recall of DAC register settings and device configuration, ensuring settings are retained during power loss.

Designed for efficiency, the MCP4716A0T-E/CH operates with low power consumption, drawing 210 µA typical in normal operation and only 60 nA typical in power-down mode. Power-down modes allow for output buffer disconnection and selection of VOUT pull-down resistors. The device communicates via an I2C interface supporting standard, fast, and high-speed modes.

This DAC is available in a compact 6-lead SOT-23 package, suitable for surface mounting. It operates within an extended temperature range of -40°C to +125°C, making it robust for demanding environments. Applications include set point or offset trimming, sensor calibration, low-power portable instrumentation, PC peripherals, data acquisition systems, and motor control.
