MAX5812LEUT+T Datasheet PDF - Maxim Integrated

●The MAX5812LEUT+T from Maxim Integrated Products is a 12bit low power, 2-wire, serial voltage-output digital to analogue converter (DAC) in 6 pin SOT-23 package. This device operates from a single supply and draws only 100µA at VDD = 3.6V. A low power, power down mode decreases current consumption to less than 1µA. The MAX5812 features three software-selectable power-down output impedances of 100Kohm, 1Kohm and high impedance. All logic inputs are CMOS-logic compatible and buffered with Schmitt triggers allowing direct interfacing to optocoupled and transformer-isolated interfaces. Other features include an internal precision rail to rail output buffer and a power-on reset (POR) circuit that powers up the DAC in the 100Kohm power down mode. Typically used at digital gain and offset adjustments, programmable voltage and current sources, programmable attenuation, VCO/varactor diode control, low-cost instrumentation and battery operated equipment.
