The MAX5530/MAX5531 are single, 12-bit, ultra-low- power, 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 6µA, making them desirable for low-power and low-voltage applications. A shutdown mode reduces overall current, including the reference input current, to just 0.18µA. The MAX5530/MAX5531 use a 3-wire serial interface that is compatible with SPI™, QSPI™, and MICROWIRE™.
At power-up, the MAX5530/MAX5531 outputs are driven to zero scale, providing additional safety for applications that drive valves or for other transducers that must be off during power-up. The zero-scale outputs enable glitch- free power-up.
The MAX5530 accepts an external reference input. The MAX5531 contains an internal reference and provides an external reference output. Both devices have force-sense-configured output buffers.
The MAX5530/MAX5531 are available in a 4mm x 4mm x 0.8mm, 12-pin, thin QFN package and are guaranteed over the extended -40°C to +85°C temperature range.
For 10-bit compatible devices, refer to the MAX5520/MAX5521 data sheet. For 8-bit compatible devices, refer to the MAX5510/MAX5511 data sheet.
