The MAX5631/MAX5632/MAX5633 are 16-bit digital-to-
analog converters (DACs) with 32 sample-and-hold
(SHA) outputs for applications where a high number of
programmable voltages are required. These devices
include a clock oscillator and a sequencer that updates
the DAC with codes from an internal SRAM. No external
components are required to set offset and gain.
The MAX5631/MAX5632/MAX5633 feature a -4.5V to
+9.2V output voltage range. Other features include a
200µV/step resolution, with output linearity error, typi-
cally 0.005% of full-scale range (FSR). The 100kHz
refresh-rate updates each SHA every 320µs, resulting
in negligible output droop. Remote ground sensing
allows the outputs to be referenced to the local ground
of a separate device.
These devices are controlled through a 20MHz
SPI™/QSPI™/MICROWIRE™-compatible 3-wire serial
interface. Immediate Update Mode allows any chan-
nel’s output to be updated within 20µs. Burst Mode
allows multiple values to be loaded into memory in a
single, high-speed data burst. All channels are updated
within 330µs after data has been loaded.
Each device features an output clamp and output resis-
tors for filtering. The MAX5631 features a 50Ω output
impedance and is capable of driving up to 250pF of out-
put capacitance. The MAX5632 features a 500Ω output
impedance and is capable of driving up to 10nF of output
capacitance. The MAX5633 features a 1kΩ output imped-
ance and is capable of driving up to 10nF of output
capacitance.
The MAX5631/MAX5632/MAX5633 are available in 12mm
x 12mm, 64-pin TQFP, and 10mm x 10mm, 68-pin thin
QFN packages.
