General Description
The MAX5820 is a dual, 8-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
(115A at VDD = 3.6V). A power-down mode decreases
current consumption to less than 1A. The MAX5820 fea-
tures three software-selectable power-down output
impedances: 100k
Ω, 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 100k
Ω power-down mode.
The MAX5820 features a double-buffered I2C-compatible
serial interface that allows multiple devices to share a sin-
gle bus. All logic inputs are CMOS-logic compatible and
buffered with Schmitt triggers, allowing direct interfacing
to optocoupled and transformer-isolated interfaces. The
MAX5820 minimizes digital noise feedthrough by discon-
necting the clock (SCL) signal from the rest of the device
when an address mismatch is detected.
The MAX5820 is specified over the extended (-40°C to
+85°C) temperature range and is available in a small
8-pin MAX package. Refer to the MAX5822 data
sheet for the 12-bit version and to the MAX5821 data
sheet for a 10-bit version.
