MAX5520/MAX5521
+1.8V to +5.5V, Ultra-Low-Power, 10-Bit, Voltage-Output DACs
General Description
The MAX5520/MAX5521 are single, 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 6µA, making them desirable for lowpower and low-voltage applications. A shutdown mode reduces overall current, including the reference input current, to just 0.18µA. The MAX5520/MAX5521 use a 3-wire serial interface that is compatible with SPI™, QSPI™, and MICROWIRE™.
At power-up, the MAX5520/MAX5521 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 MAX5520 accepts an external reference input. The MAX5521 contains an internal reference and provides an external reference output. Bo...
