MAX5318GUG+

The MAX5318GUG+ is a 18bit, high accuracy voltage output DAC in 24 pin TSSOP package. This DAC voltage output is buffered resulting in a fast settling time of 3µs and a low offset and gain drift of ±0.5ppm/°C 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. It includes user-programmable digital gain and offset correction to enable easy system calibration. At power-up, device resets its outputs to zero or midscale. The integrated low drift, low noise reference buffer amplifier makes it ease of use. It is used in automatic test equipment, gain and offset adjustment, data-acquisition systems, process control and servo loops, programmable voltage and current sources and automatic tuning and calibration.

• Supply voltage range is 2.7V to 5.5V
• Operating temperature range from -40°C to 105°C
• Ideal for ATE and high-precision instruments, INL accuracy of ±2LSB (max) over temperature
• Fast settling time of 3µs with 10Kohm, 100pF load
• Predetermined output device state in power-up and reset in system design
• Negative supply (AVSS) option allows full INL and DNL performance to 0V
• SPI interface compatible with 1.8V to 5.5V logic
• High integration reduces development time and PCB area, integrated reference buffer
• Buffered voltage output directly drives 2Kohm load rail to rail, no external amplifiers required
