... Resistive String DAC Op Amp OUT © 2007 Microchip Technology Inc. MCP4725 in SOT-23-6 DESCRIPTION The MCP4725 is a low-power, high accuracy, single channel, 12-bit buffered voltage output Digital-to-Ana- log Convertor (DAC) with non-volatile memory (EEPROM). Its on-board precision output amplifier allows it to achieve rail-to-rail analog output swing. ...
