General Description
The MAX5590–MAX5595 octal, 12/10/8-bit, voltage-out-
put digital-to-analog converters (DACs) offer buffered
outputs and a 3µs maximum settling time at the 12-bit
level. The DACs operate from a +2.7V to +5.25V analog
supply and a separate +1.8V to +5.25V digital supply.
The 20MHz 3-wire serial interface is compatible with
SPI™, QSPI™, MICROWIRE™, and digital signal
processor (DSP) protocol applications. Multiple devices
can share a common serial interface in direct-access or
daisy-chained configuration. The MAX5590–MAX5595
provide two multifunction, user-programmable, digital
I/O ports. The externally selectable power-up states of
the DAC outputs are either zero scale, midscale, or full
scale. Software-selectable FAST and SLOW settling
modes decrease settling time in FAST mode, or reduce
supply current in SLOW mode.
The MAX5590/MAX5591 are 12-bit DACs, the MAX5592/
MAX5593 are 10-bit DACs, and the MAX5594/
MAX5595 are 8-bit DACs. The MAX5590/MAX5592/
MAX5594 provide unity-gain-configured output buffers,
while the MAX5591/MAX5593/MAX5595 provide force-
sense-configured output buffers. The MAX5590–
MAX5595 are specified over the extended -40°C to
+85°C temperature range, and are available in space-
saving 24-pin and 28-pin TSSOP packages.

Note 1:
For the force-sense versions, FB_ is connected to its respective OUT_. VOUT (max) = VREF / 2, unless otherwise noted.
Note 2:
Linearity guaranteed from decimal code 40 to code 4095 for the MAX5590B/MAX5591B (12-bit, B-grade), code 10 to code
1023 for the MAX5592/MAX5593 (10-bit), and code 3 to code 255 for the MAX5594/MAX5595 (8-bit).
Note 3:
Represents the functional range. The linearity is guaranteed at VREF = 2.5V (for AVDD from 2.7V to 5.25V), and VREF =
4.096V (for AVDD = 4.5V to 5.25V). See the
Typical Operating Characteristics
section for linearity at other voltages.
Note 4:
DC crosstalk is measured as follows: outputs of DACA–DACH are set to full scale and the output of DACH is measured.
While keeping DACH unchanged, the outputs of DACA–DACG are transitioned to zero scale and the
∆V
OUT of DACH is
measured.
Note 5:
Guaranteed by design.
Note 6:
The reference -3dB bandwidth is measured with a 0.1VP-P sine wave on VREF and with full-scale input code.
