MAX5316

16-Bit, ±1 LSB Accuracy Voltage Output DAC with SPI Interface

Lowest Noise, Fast-Settling Precision 16-Bit DAC


Please check latest availability status for a specific part variant.

Description

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 ±1 LSB INL (max) accuracy and a ±0.25 LSB DNL (typ) accuracy over the temperature range of -40°C to +105°C.

The DAC voltage output is buffered with a fast settling time of 3µs and a low offset and gain drift of ±0.6ppm/°C of FSR (typ). The force-sense output (OUT) maintains accuracy while driving loads with long lead lengths. A separate AVSS supply is provided to permit 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 integrated low-drift, low-noise reference buffer make for ease of use. The MAX5316 features a 50MHz 3-wire SPI interface. For an I²C interface, use the MAX5317.

The MAX5316 is available in a 24-lead TQFN-EP package and operates over the -40°C to +105°C temperature range.
