MAX5811LEUT+T
10-Bit, Low-Power, 2-Wire Interface, Serial, Voltage-Output DAC
General DescriptionThe MAX5811 is a single, 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 100µA at VDD= 3.6V. A low-power power-
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®output buffer and a power-on reset (POR)
circuit that powers up the DAC in the 100kΩpower-down
mode.
The MAX5811 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
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.

MAX5811
10-Bit Low Power 2-Wire Interface Serial,
Voltage-Output DAC
Detailed DescriptionThe MAX5811 is a 10-bit, voltage-output DAC with an
I2C/SMBus-compatible 2-wire interface. The device
consists of a serial interface, power-down circuitry,
input and DAC registers, a 10-bit resistor string DAC,
unity-gain output buffer, and output resistor network.
The serial interface decodes the address and control
bits, routing the data to either the input or DAC register.
Data can be directly written to the DAC register imme-
diately updating the device output, or can be written to
the input register without changing the DAC output.
Both registers retain data as long as the device is pow-
ered.
DAC OperationThe MAX5811 uses a segmented resistor string DAC
architecture, which saves power in the overall system
and guarantees output monotonicity. The MAX5811’s
input coding is straight binary, with the output voltage
given by the following equation:
where N = 10 (bits), and D = the decimal value of the
input code (0 to 1023).
Output BufferThe MAX5811 analog output is buffered by a precision,
unity-gain follower that slews at about 0.5V/µs. The
buffer output swings rail-to-rail, and is capable of dri-
ving 5kΩin parallel with 200pF. The output settles to
±0.5LSB within 4µs.
Power-On ResetThe MAX5811 features an internal POR circuit that ini-
tializes the device upon power-up. The DAC registers
are set to zero scale and the device is powered-down
with the output buffer disabled and the output pulled to
GND through the 100kΩtermination resistor. Following
power-up, a wake-up command must be initiated
before any conversions are performed.
Power-Down ModesThe MAX5811 has three software-controlled low-power
power-down modes. All three modes disable the output
buffer and disconnect the DAC resistor string from VDD,
reducing supply current draw to 300nA. In power-down
mode 0, the device output is high impedance. In
power-down mode 1, the device output is internally
pulled to GND by a 1kΩtermination resistor. In power-
down mode 2, the device output is internally pulled to
GND by a 100kΩtermination resistor. Table 1shows
the power-down mode command words.
Upon wake-up, the DAC output is restored to its previ-
ous value. Data is retained in the input and DAC regis-
ters during power-down mode.
Digital Interface The MAX5811 features an I2C/SMBus-compatible 2-
wire interface consisting of a serial data line (SDA) andVD
