General Description
The MAX5841 is a quad, 10-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 230A at VDD = 3.6V. A power-
down mode decreases current consumption to less
than 1A. The MAX5841 features three software-selec-
table power-down output impedances: 100k
, 1k,
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
power-down mode.
The MAX5841 features a double-buffered I2C-compati-
ble serial interface that allows multiple devices to share
a single bus. All logic inputs are CMOS-logic compati-
ble and buffered with Schmitt triggers, allowing direct
interfacing to optocoupled and transformer-isolated
interfaces. The MAX5841 minimizes digital noise
feedthrough by disconnecting the clock (SCL) signal
from the rest of the device when an address mismatch
is detected.
The MAX5841 is specified over the extended tempera-
ture range of -40°C to +85°C and is available in a
miniature 10-pin MAX package. Refer to the MAX5842
data sheet for the 12-bit version.
