MAX5842
Quad, 12-Bit, Low-Power, 2-Wire, Serial Voltage-Output DAC
|
Status
Active: In Production.
Description
The MAX5842 is a quad, 12-bit voltage-output, digital-to-analog converter (DAC) with an I²C-compatible, 2-wire interface that operates at clock rates up to 400kHz. The device operates from a single 2.7V to 5.5V supply and draws only 230µA at VDD = 3.6V. A power-down mode decreases current consumption to less than 1µA. The MAX5842 features three software-selectable power-down output impedances: 100kΩ, 1kΩ, and high impedance. Other features include internal precision Rail-to-Rail output buffers and a power-on reset (POR) circuit that powers up the DAC in the 100kΩ power-down mode.
The MAX5842 features a double-buffered I²C-compatible serial interface that allows multiple devices to share a single bus. All logic inputs are CMOS-logic compatible and buffered with Schmitt triggers, allowing direct interfacing to optocoupled and transformer-isolated interfaces. The MAX5842 minimizes digital noise feedthrough by disconnecting the clock (SCL) signal from the rest of the device when an address mismatch is detected.
The MAX5842 is specified over the extended temperature range of -40°C to +85°C and is available in a miniature 10-pin µMAX® package. Refer to the MAX5841 data sheet for the 10-bit version.
