The MAX5811 is a single, 10-bit voltage-output digital-to-
analog converter (DAC) with an I
interface that operates at clock rates up to 400kHz. The
device operates from a single 2.7V to 5.5V supply and
draws only 100µA at V
down mode decreases current consumption to less than
1µA. The MAX5811 features three software-selectable
power-down output impedances: 100kΩ, 1kΩ, and high
impedance. Other features include an internal precision
Rail-to-Rail
circuit that powers up the DAC in the 100kΩ power-down
mode.
The MAX5811 features a double-buffered I
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
MAX5811 minimizes digital noise feedthrough by discon-
necting the clock (SCL) signal from the rest of the device
when an address mismatch is detected.
The MAX5811 is specified over the extended temperature
range of -40°C to +85°C and is available in a space-sav-
ing 6-pin SOT23 package. Refer to the MAX5812 data
sheet for the 12-bit version.
