General Description
The MAX5621/MAX5622/MAX5623 are 16-bit digital-to-
analog converters (DACs) with 16 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 MAX5621/MAX5622/MAX5623 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 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 after data has been loaded.
Each device features an output clamp and output resis-
tors for filtering. The MAX5621 features a 50
output
impedance and is capable of driving up to 250pF of out-
put capacitance. The MAX5622 features a 500
output
impedance and is capable of driving up to 10nF of output
capacitance. The MAX5623 features a 1k
output imped-
ance and is capable of driving up to 10nF of output
capacitance.
The MAX5621/MAX5622/MAX5623 are available in 64-pin
TQFP (10mm x 10mm) and 68-pin thin QFN (10mm x
10mm) packages.
