General Description

The MAX5510/MAX5511 are single, 8-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 MAX5510/MAX5511 use a

3-wire serial interface that is compatible with SPI™,

QSPI™, and MICROWIRE™.

At power-up, the MAX5510/MAX5511 outputs are dri-

ven to zero scale, providing additional safety for appli-

cations that drive valves or for other transducers that

must be off during power-up. The zero-scale outputs

enable glitch-free power-up.

The MAX5510 accepts an external reference input. The

MAX5511 contains an internal reference and provides

an external reference output. Both devices have force-

sense-configured output buffers.

The MAX5510/MAX5511 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 12-bit compatible devices, refer to the MAX5530/

MAX5531 data sheet. For 10-bit compatible devices,

refer to the MAX5520/MAX5521 data sheet.
