Description

The MAX5522-MAX5525 are dual, 10-bit, ultra-lowpower,voltage-output, digital-to-analog converters(DACs) offering rail-to-rail buffered voltage outputs. TheDACs operate from a 1.8V to 5.5V supply and consumeless than 5µA, making the devices suitable for lowpowerand low-voltage applications. A shutdown modereduces overall current, including the reference inputcurrent, to just 0.18µA. The MAX5522-MAX5525 use a3-wire serial interface that is compatible with SPI™,QSPI™, and MICROWIRE™.Upon power-up, the MAX5522-MAX5525 outputs aredriven to zero scale, providing additional safety forapplications that drive valves or for other transducersthat need to be off during power-up. The zero-scaleoutputs enable glitch-free power-up.The MAX5522 accepts an external reference input andprovides unity-gain outputs. The MAX5523 contains aprecision internal reference and provides a bufferedexternal reference output with unity-gain DAC outputs.The MAX5524 accepts an external reference input andprovides force-sense outputs. The MAX5525 contains aprecision internal reference and provides a bufferedexternal reference output with force-sense DAC outputs.The MAX5524/MAX5525 are available in a 4mm x 4mmx 0.8mm, 12-pin, thin QFN package. The MAX5522/MAX5523 are available in an 8-pin µMAX package. Alldevices are guaranteed over the extended -40°C to+85°C temperature range.For 12-bit compatible devices, refer to the MAX5532-MAX5535 data sheet. For 8-bit compatible devices,refer to the MAX5512-MAX5515 data sheet.ApplicationsAutomatic Trimming and Calibration in Factory or FieldChemical Sensor Cell Bias for Gas MonitorsIndustrial Process Control and Remote Industrial DevicesPortable Battery-Powered Devices InstrumentationProgrammable LCD BiasProgrammable Voltage and Current SourcesRemote Data Conversion and Monitoring
