Quad, 10-Bit, Low-Power, 2-Wire, Serial Voltage-Output DAC
General DescriptionThe 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 230µA at VDD= 3.6V. A power-
down mode decreases current consumption to less
than 1µA. The MAX5841 features three software-selec-
table power-down output impedances: 100kΩ, 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
100kΩpower-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 µMAX package. Refer to the MAX5842
data sheet for the 12-bit version.

MAX5841
Quad, 10-Bit, Low-Power, 2-Wire, Serial
Voltage-Output DAC
Detailed DescriptionThe MAX5841 is a quad, 10-bit, voltage-output DAC
with an I2C/SMBus-compatible 2-wire interface. The
device consists of a serial interface, power-down cir-
cuitry, four input and DAC registers, four 10-bit resistor
string DACs, four unity-gain output buffers, and output
resistor networks. The serial interface decodes the
address and control bits, routing the data to the proper
input or DAC register. Data can be directly written to
the DAC register, immediately updating the device out-
put, or can be written to the input register without
changing the DAC output. Both registers retain data as
long as the device is powered.
DAC OperationThe MAX5841 uses a segmented resistor string DAC
architecture, which saves power in the overall system
and guarantees output monotonicity. The MAX5841’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 MAX5841 analog outputs are buffered by preci-
sion, unity-gain followers that slew 0.5V/µs. Each buffer
output swings rail-to-rail, and is capable of driving 5kΩ
in parallel with 200pF. The output settles to ±0.5LSB
within 4µs.
Power-On ResetThe MAX5841 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 buffers disabled and the outputs pulled
to GND through the 100kΩtermination resistor.
Following power-up, a wake-up command must be initi-
ated before any conversions are performed.
Power-Down ModesThe MAX5841 has three software-controlled low-power
power-down modes. All three modes disable the output
buffers and disconnect the DAC resistor strings from
REF, reducing supply current draw to 1µA and the ref-
erence current draw to less than 1µA. 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 1 shows
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 MAX5841 features an I2C/SMBus-compatible
2-wire interface consisting of a serial data line (SDA)
and a serial clock line (SCL). The MAX5841 is SMBus
compatible within the range of VDD= 2.7V to 3.6V. SDA
and SCL facilitate bidirectional communication between
the MAX5841 and the master at rates up to 400kHz.
Figure 1 shows the 2-wire interface timing diagram. The
MAX5841 is a transmit/receive slave-only device, rely-
ing upon a master to generate a clock signal. The mas-
ter (typically a microcontroller) initiates data transfer on
the bus and generates SCL to permit that transfer.
A master device communicates to the MAX5841 by
transmitting the proper address followed by command
and/or data words. Each transmit sequence is framed-VD
