_______________General DescriptionThe MAX5152/MAX5153 low-power, serial, voltage-out-
put, dual 13-bit digital-to-analog converters (DACs)
consume only 500µA from a single +5V (MAX5152) or
+3V (MAX5153) supply. These devices feature Rail-to-
Rail®output swing and are available in space-saving
16-pin QSOP and DIP packages. Access to the invert-
ing input allows for specific gain configurations, remote
sensing, and high output current capability, making
these devices ideally suited for industrial process con-
trols. These devices are also well suited for digitally
programmable (4–20mA) current loops.
The 3-wire serial interface is SPI™/QSPI™ and
Microwire™ compatible. Each DAC has a double-
buffered input organized as an input register followed
by a DAC register, which allows the input and DAC reg-
isters to be updated independently or simultaneously.
Additional features include a programmable shutdown
(2µA), hardware-shutdown lockout, a separate voltage
reference for each DAC, power-on reset, and an active-
low clear input (CL) that resets all registers and DACs
to zero. The MAX5152/MAX5153 provide a programma-
ble logic output pin for added functionality, and a seri-
al-data output pin for daisy chaining.

MAX5152/MAX5153
_______________Detailed DescriptionThe MAX5152/MAX5153 dual, 13-bit, voltage-output
DACs are easily configured with a 3-wire serial inter-
face. These devices include a 16-bit data-in/data-out
shift register, and each DAC has a double-buffered
input comprised of an input register and a DAC register
(see Functional Diagram). Both DACs use an inverted
R-2R ladder network that produces a weighted voltage
proportional to the input voltage value. Each DAC has
its own reference input to facilitate independent full-
scale values. Figure 1 depicts a simplified circuit dia-
gram of one of the two DACs.
Reference InputsThe reference inputs accept both AC and DC values
with a voltage range extending from 0V to (VDD- 1.4V).
Determine the output voltage using the following equa-
tion:
VOUT= VREFx NB / 8192
where NB is the numeric value of the DAC’s binary input
code (0 to 8191) and VREFis the reference voltage.
The reference input impedance ranges from 14kΩ(1555
hex) to several giga ohms (with an input code of 0000
hex). This reference input capacitance is code depen-
dent and typically ranges from 15pF with an input code
of all zeros to 50pF with an input code of all ones.
Output AmplifierThe output amplifier’s inverting input is available to the
user, allowing force and sense capability for remote
sensing and specific gain configurations. The inverting
input can be connected to the output to provide a unity-
gain buffered output. The output amplifiers have a typi-
cal slew rate of 0.75V/µs and settle to 1/2LSB within
25µs, with a load of 10kΩin parallel to 100pF. Loads
less than 2kΩdegrade performance.

______________________________________________________________Pin Description
MAX5152/MAX5153
Power-Down ModeThe MAX5152/MAX5153 feature a software-program-
mable shutdown mode that reduces the typical supply
current to 2µA. The two DACs can be shut down inde-
pendently or simultaneously by using the appropriate
programming word. For instance, enter shutdown mode
(for both DACs) by writing an input control word of
111XXXXXXXXXXXXX (Table 1). In shutdown mode, the
reference inputs and amplifier outputs become high
impedance, and the serial interface remains active.
Data in the input registers is saved, allowing the
MAX5152/MAX5153 to recall the output state prior to
entering shutdown when returning to normal mode. Exit
shutdown by recalling the previous condition or by
updating the DAC with new information. When returning
to normal operation (exiting shutdown), wait 20µs for
output stabilization.
Serial Interface The MAX5152/MAX5153 3-wire serial interface is com-
patible with both Microwire (Figure 2) and SPI/QSPI
(Figure 3) serial-interface standards. The 16-bit serial
input word consists of an address bit, two control bits,
and 13 bits of data (MSB to LSB) as shown in Figure 4.
The address and control bits determines the response
of the MAX5152/MAX5153, as outlined in Table 1.
The MAX5152/MAX5153’s digital inputs are double
buffered, which allows any of the following: loading the
input register(s) without updating the DAC register(s),
updating the DAC register(s) from the input register(s),
or updating the input and DAC registers concurrently.
The address and control bits allow for the DACs to act
independently.
