MAX5318
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.
Key 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
