MAX5719GSD+

The MAX5719GSD+ is a serial input, unbuffered 20bit voltage output unipolar digital to analogue converter in 14 pin SO package. This DAC comes with integrated feedback resistors that allow bipolar operation when used with an external operational amplifier. The DAC provides low glitch energy, low noise, tight bipolar resistor matching and high accuracy. It features ±64.0LSB INL (max, 20bit) over temperature range of -40°C to +105°C. Integrated precision setting resistors makes DAC easy to use. It features a 50MHz, 3-wire SPI, QSPI, MICROWIRE and DSP-compatible serial interface. On power-up, the output resets to zero-scale, providing additional safety for applications which drive valves or other transducers that need to be off on power-up. The DAC output settles in 750ns and has a low offset and gain drift of ±0.1ppm/°C of FSR. It is used in gain and offset adjustment, data-acquisition systems, automatic tuning, programmable voltage and current sources, process control and servo loops.

• Supply range from 4.5V to 5.5V
• Reference input range from 4V to VDD
• ±2LSB DNL (max, 16bit)
• 0.05nV-sec glitch energy
• Output noise density is 6nv/√Hz
• Integrated ±0.025% (max) bipolar setting resistors
• Safe power-up reset-to-zero-scale DAC output (unipolar)
