MAX5318 Datasheet | Maxim Integrated

EVALUATION KIT AVAILABLE 18-Bit, High-Accuracy Voltage Output DAC with Digital Gain, Offset Control, and SPI Interface General Description The MAX5318 is a high-accuracy, 18-bit, serial SPI input, buffered voltage output digital-to-analog converter (DAC) in a 4.4mm x 7.8mm, 24-lead TSSOP package. The device Features Q2 LSB INL (max) accuracy and a Q1 LSB DNL (max) accuracy over the full temperature range of -40NC to +105NC. The DAC voltage output is buffered resulting in a fast settling time of 3Fs and a low offset and gain drift of Q0.5ppm/NC of FSR (typ). The force-sense output (OUT) maintains accuracy while driving loads with long lead lengths. Additionally, a separate AVSS supply, allows the output amplifier to go to 0V (GND) while maintaining full linearity performance. The MAX5318 includes user-programmable digital gain and offset correction to enable easy system calibration. 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 amplifier make for ease of use. The MAX5318 Features a 50MHz 3-wire SPI interface. The MAX5318 is available in a 24-lead TSSOP package and operates over the -40NC to +105NC temperature range.
