Description
12-bit Dacs With 32-channel Sample-and-hold Outputs
Manufacturer
Maxim Integrated Products, Inc.
Datasheet
The MAX5331/MAX5332/MAX5333 are 12-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 MAX5331/MAX5332/MAX5333 feature a -4.5V to
+9.2V output voltage range. Other features include a
3.2mV/step resolution, with output linearity error, typi-
cally 0.03% 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 channel’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 of data being loaded.
Each device features an output clamp and output resis-
tors for filtering. The MAX5331 features a 50Ω output
impedance and is capable of driving up to 250pF of
output capacitance. The MAX5332 features a 500Ω out-
put impedance and is capable of driving up to 10nF of
output capacitance. The MAX5333 features a 1kΩ out-
put impedance and is capable of driving up to 10nF of
output capacitance.
The MAX5331/MAX5332/MAX5333 are available in 12mm
x 12mm, 64-pin TQFP and 10mm x 10mm, 68-pin thin
QFN packages.
