The MAX5773/MAX5774/MAX5775 are 32-channel, 14-
bit, voltage-output DACs. All devices accept a +3.0V
external reference input at REF. An internal offset DAC
allows all outputs to be offset up to -5V (see Table 1).
A 33MHz SPI-/QSPI-/MICROWIRE- or DSP-compatible
serial interface (see Figure 1) controls the
MAX5773/MAX5774/MAX5775. Use DSP to select the
DSP mode or the SPI/QSPI/MICROWIRE mode.
Each DAC has a double-buffered input structure to
minimize the digital-noise feedthrough from the digital
inputs to the outputs. The two buffers are organized as
32-Channel, 14-Bit, Voltage-Output
DACs with Serial Interface

Exposed Paddle. Connect to V
an input register followed by a DAC register. Input reg-
isters update the DAC registers independently or simul-
taneously with a single software or hardware command.
Each DAC channel has its own offset and gain registers
that calibrate offset and gain errors for a given channel.
The MAX5773/MAX5774/MAX5775 are divided into two
banks of 16 channels to provide real-time calibration of
channel pairs. Channel bank pairs are ordered as
(bank 0:bank 1) OUT0:OUT16, OUT1:OUT17 …
OUT14:OUT30, OUT15:OUT31.
An offset DAC allows all the outputs to be offset up to
-5V and dual ground-sensing inputs (GS1 and GS2)
allow the output voltages to be referenced to remote
SS
