The MAX5722EUA+ is a 12bit, low power, dual, voltage output DAC with serial interface in 8 pin μMAX package. This dual buffered DAC consumes 112μA supply current, DAC outputs employ on-chip precision output amplifiers that swing Rail to Rail and the reference input accepts a voltage range from 0 to VDD. In power-down, the reference input is high impedance, further reducing system's total power consumption. The on-chip power-on reset (POR) circuit resets DAC outputs to zero and loads output with a 100Kohm resistor to ground. This provides additional safety for applications that drive valves or other transducers that need to be off on power-up. Device is used in gain and offset adjustment, power amplifier control, process control I/O boards and VCO control.
- Supply voltage range is 2.7V to 5.5V
- Operating temperature range from -40°C to 85°C
- Ultra low power consumption of 135μA at VDD = +5.5V
- 0.3μA power-down current
- Safe power-up reset to zero volts at DAC output
- Three software-selectable power-down impedances (100Kohm, 1Kohm & Hi-Z)
- Fast 20MHz, 3-wire SPI, QSPI and MICROWIRE compatible serial interface
- Schmitt-triggered logic inputs for direct interfacing to optocouplers
- Maximum INL is ±16LSB & maximum DNL is ±1LSB at monotonic
