DAC8531

SBAS192B – MARCH 2001 – REVISED JUNE 2003

Low-Power, Rail-to-Rail Output, 16-Bit Serial Input

DIGITAL-TO-ANALOG CONVERTER

DESCRIPTION

FEATURES

The DAC8531 is a low-power, single, 16-bit buffered voltage

output Digital-to-Analog Converter (DAC). Its on-chip preci-

sion output amplifier allows rail-to-rail output swing to be

achieved. The DAC8531 uses a versatile three-wire serial

interface that operates at clock rates up to 30MHz and is

compatible with standard SPI™, QSPI™, Microwire™, and

Digital Signal Processor (DSP) interfaces.

ꢀꢀmicroPower OPERATION: 250

µA at 5V

ꢀ POWER-ON RESET TO ZERO

ꢀ POWER SUPPLY: +2.7V to +5.5V

ENSURED MONOTONIC BY DESIGN

ꢀ

ꢀ SETTLING TIME: 10µs to ±0.003 FSR

ꢀ LOW-POWER SERIAL INTERFACE WITH

The DAC8531 requires an external reference voltage to set

the output range of the DAC. The DAC8531 incorporates a

power-on reset circuit that ensures that the DAC output

powers up at 0V and remains there until a valid write takes

place to the device. The DAC8531 contains a power-down

feature, accessed over the serial interface, that reduces the

current consumption of the device to 200nA at 5V.

ꢀ ON-CHIP OUTPUT BUFFER AMPLIFIER,

RAIL-TO-RAIL OPERATION

ꢀ SYNC INTERRUPT FACILITY

ꢀ PACKAGES: MSOP-8 and 3x3 SON-8 (same

size as QFN)

The low power consumption of this part in normal operation

makes it ideally suited to portable battery-operated equip-

ment. The power consumption is 2mW at 5V reducing to 1µW

in power-down mode.

APPLICATIONS

The DAC8531 is available in both MSOP-8 and 3x3 SON-8

(same size as QFN) packages.
