MAX5316
16-Bit, ±1 LSB Accuracy Voltage Output
DAC with SPI Interface
General Description
Benefits and Features
The MAX5316 is a high-accuracy, 16-bit, serial SPI input,
buffered voltage output digital-to-analog converter (DAC)
in a 4mm x 5mm, 24-lead TQFN package. The device
features Q1 LSB INL (max) accuracy and a Q0.25 LSB
DNL (typ) accuracy over the temperature range of -40NC
to +105NC.
The DAC voltage output is buffered with a fast set-
tling time of 3Fs and a low offset and gain drift of
Q0.6ppm/NC of FSR (typ). The force-sense output (OUT)
maintains accuracy while driving loads with long lead
lengths. A separate AVSS supply pin is provided to per-
mit the output amplifier to go to 0V (GND) to maintain full
linearity performance near ground.
At power-up, the device resets its outputs to zero or
midscale.
The wide 2.7V to 5.5V supply voltage range and inte-
grated low-drift, low-noise reference buffer make for ease
of use. The MAX5316 features a 50MHz 3-wire SPI inter-
face. For an I²C interface, use the MAX5317.
The MAX5316 is available in a 24-lead TQFN-EP pack-
age and operates over the -40NC to +105NC temperature
range.
