Quad/Octal, 2-Wire Serial 8-Bit DACs

with Rail-to-Rail Outputs

_______________General Description

The MAX520/MAX521 are quad/octal, 8-bit voltage-output

digital-to-analog converters (DACs) with simple 2-wire ser-

ial interfaces that allow communication between multiple

devices. They operate from a single +5V supply and their

reference input range includes both supply rails.

The MAX521 includes rail-to-rail output buffer amplifiers for

reduced system size and component count when driving

loads. The MAX520’s unbuffered voltage outputs reduce

the device’s total supply current to 4µA and provide

increased accuracy at low output currents.

The MAX520/MAX521 feature a serial interface and internal

software protocol, allowing communication at data rates up

to 400kbps. The interface, combined with the double-

buffered input configuration, allows the DAC registers to be

updated individually or simultaneously. In addition, the

devices can be put into a low-power shutdown mode that

reduces supply current to 4µA. Power-on reset ensures the

DAC outputs are at 0V when power is initially applied.

The MAX520 is available in 16-pin DIP and wide SO pack-

ages, as well as a space-saving 20-pin SSOP. The

MAX521 comes in 20-pin DIP and 24-pin SO packages, as

well as a space-saving 24-pin SSOP.
