MCP4725A3T-E/CH

MCP4725A3T-E/CH is a low-power, high accuracy, single channel, 12-bit buffered voltage output Digital-to Analog Converter (DAC) with non-volatile memory (EEPROM). Its on-board precision output amplifier allows it to achieve rail-to-rail analogue output swing. The DAC input and configuration data can be programmed to the non-volatile memory (EEPROM) by the user using I2C interface command. The non-volatile memory feature enables the DAC device to hold the DAC input code during power-off time, and the DAC output is available immediately after power-up. This feature is very useful when the DAC device is used as a supporting device for other devices in the network. The device includes a Power-on-Reset (POR) circuit to ensure reliable power-up and an on-board charge pump for the EEPROM programming voltage. The DAC reference is driven from VDD directly. In power down mode, the output amplifier can be configured to present a known low, medium, or high resistance output load.
