+5V/+3V, 12-Bit, Serial, Force/Sense DACs With 10ppm/?ƃ Internal Reference

The MAX5122 MAX5123 low-power, 12-bit, voltage-out- put, digital-to-analog converters (DACs) feature an inter- nal precision bandgap reference and output Amplifier The MAX5122 operates on a single +5V supply with an internal +2.5V reference, and offers a configurable output Amplifier If necessary, the user CAN override the on-chip, <10ppm/C Voltage Reference with an external reference. The MAX5123 has the same features as the MAX5122 but operates from a single +3V supply and has an internal +1.25V precision reference. The user-accessible inverting input and output of the Amplifier allows specific gain con- figurations, remote sensing, and high output drive capa- bility for a wide range of force/sense applications. Both devices draw only 500A of supply current, which reduces to 3A in power-down mode. In addition, their power-up reset feature allows for a user-selectable initial output state of either 0V or midscale and reduces output glitches during power-up. By Maxim Integrated Products
