MAX5523:Dual, Ultra-Low-Power, 10-Bit, Voltage-Output DACs

The MAX5522-MAX5525 are dual, 10-bit, ultra-lowpower, voltage-output, digital-to-analog converters (DACs) offering rail-to-rail buffered voltage outputs. The DACs operate from a 1.8V to 5.5V supply and consume less than 5µA, making the devices suitable for lowpower and low-voltage applications. A shutdown mode reduces overall current, including the reference input current, to just 0.18µA. The MAX5522-MAX5525 use a 3-wire serial interface that is compatible with SPI™, QSPI™, and MICROWIRE™. Upon power-up, the MAX5522-MAX5525 outputs are driven to zero scale, providing additional safety for applications that drive valves or for other transducers that need to be off during power-up. The zero-scale outputs enable glitch-free power-up. The MAX5522 accepts an external reference input and provides unity-gain outputs. The MAX5523 contains a precision internal reference and provides a buffered external reference output with unity-gain DAC outputs. The MAX5524 accepts an external reference input and provides force-sense outputs. The MAX5525 contains a precision internal reference and provides a buffered external reference output with force-sense DAC outputs. The MAX5524/MAX5525 are available in a 4mm x 4mm x 0.8mm, 12-pin, thin QFN package. The MAX5522/MAX5523 are available in an 8-pin µMAX package. All devices 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.
