MAX5304CUA
10-Bit Voltage-Output DAC in 8-Pin レMAX
General DescriptionThe MAX5304 combines a low-power, voltage-output,
10-bit digital-to-analog converter (DAC) and a precision
output amplifier in an 8-pin µMAX package. It operates
from a single +5V supply, drawing less than 280µA of
supply current.
The output amplifier’s inverting input is available to the
user, allowing specific gain configurations, remote
sensing, and high output-current capability. This makes
the MAX5304 ideal for a wide range of applications,
including industrial process control. Other features
include a software shutdown and power-on reset.
The serial interface is SPI™/QSPI™/MICROWIRE™
compatible. The DAC has a double-buffered input,
organized as an input register followed by a DAC regis-
ter. A 16-bit serial word loads data into the input regis-
ter. The DAC register can be updated independently or
simultaneously with the input register. All logic inputs
are TTL/CMOS-logic compatible and buffered with
Schmitt triggers to allow direct interfacing to optocou-
plers.

MAX5304
10-Bit Voltage-Output DAC
in 8-Pin µMAX
_______________Detailed DescriptionThe MAX5304 contains a voltage-output digital-to-ana-
log converter (DAC) that is easily addressed using a
simple 3-wire serial interface. Each IC includes a 16-bit
shift register, and has a double-buffered input com-
posed of an input register and a DAC register (see the
Functional Diagram). In addition to the voltage output,
the amplifier’s negative input is available to the user.
The DAC is an inverted R-2R ladder network that con-
verts a digital input (10 data bits plus 3 sub-bits) into an
equivalent analog output voltage in proportion to the
applied reference voltage. Figure 1 shows a simplified
circuit diagram of the DAC.
Reference InputsThe reference input accepts positive DC and AC sig-
nals. The voltage at the reference input sets the full-
scale output voltage for the DAC. The reference input
voltage range is 0V to (VDD- 1.4V). The output voltage
(VOUT) is represented by a digitally programmable volt-
age source, as expressed in the following equation:
VOUT= (VREF
·NB / 1024) Gain
where NB is the numeric value of the DAC’s binary
input code (0 to 1023), VREFis the reference voltage,
and Gain is the externally set voltage gain.
The impedance at the reference input is code depen-
dent, ranging from a low value of 18kΩwhen the DAC
has an input code of 1550 hex, to a high value exceed-
ing several gigohms (leakage currents) with an input
code of 0000 hex. Because the input impedance at the
reference pin is code dependent, load regulation of the
reference source is important.
In shutdown mode, the MAX5304’s REF input enters a
high-impedance state with a typical input leakage cur-
rent of 0.001µA.
The reference input capacitance is also code depen-
dent and typically ranges from 15pF (with an input
code of all 0s) to 50pF (at full scale).
The MAX873 +2.5V reference is recommended for use
with the MAX5304.
Output AmplifierThe MAX5304’s DAC output is internally buffered by a
precision amplifier with a typical slew rate of 0.6V/µs.
Access to the output amplifier’s inverting input provides
the user greater flexibility in output gain setting/signal
conditioning (see the Applications Informationsection).
With a full-scale transition at the MAX5304 output, the
typical settling time to ±1/2LSB is 10µs when loaded
with 5kΩin parallel with 100pF (loads less than 2kΩ
degrade performance).
The amplifier’s output dynamic responses and settling
performances are shown in the Typical Operating
Characteristics.
Shutdown ModeThe MAX5304 features a software-programmable shut-
down that reduces supply current to a typical value of
4µA. Writing 111X XXXX XXXX XXXX as the input-con-
trol word puts the device in shutdown mode (Table 1).
