MAX5820 - Serial Voltage-Output DAC

General Description

The MAX5820 is a dual, 8-bit voltage-output, digital-toanalog converter (DAC) with an I 2 C

-compatible, 2-wire interface that operates at clock rates up to 400kHz.

The device operates from a single 2.7V to 5.5V supply (115µA at VDD = 3.6V).

Key Features

  • three software-selectable power-down output impedances: 100kΩ, 1kΩ, and high impedance. Other www. DataSheet4U. com 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 MAX5820 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 o.

19-3538; Rev 0; 2/05 Dual, 8-Bit, Low-Power, 2-Wire, Serial Voltage-Output DAC General Description The MAX5820 is a dual, 8-bit voltage-output, digital-toanalog converter (DAC) with an I 2 C*-compatible, 2-wire interface that operates at clock rates up to 400kHz. The device operates from a single 2.7V to 5.5V supply (115µA at VDD = 3.6V). A power-down mode decreases current consumption to less than 1µA. The MAX5820 features three software-selectable power-down output impedances: 100kΩ, 1kΩ, and high impedance. Other www.DataSheet4U.com 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.
