MAX5530 Datasheet, PDF (1/19 Pages) Maxim Integrated Products – ULTRA-LOW POWER, 12-BIT, VOLTAGE-OUTPUT DACS

19-3063; Rev 0; 1/04
Ultra-Low-Power, 12-Bit,
Voltage-Output DACs
General Description
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 con-
sume 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.
