DAC8501

SBAS212A – APRIL 2001 – REVISED FEBRUARY 2003

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

DIGITAL-TO-ANALOG CONVERTER

DESCRIPTION

FEATURES

The DAC8501 is a low-power, single, 16-bit buffered voltage

output Digital-to-Analog Converter (DAC) optimized for multi-

plying operation. Its on-chip precision output amplifier allows

rail-to-rail output swing to be achieved. The DAC8501 uses a

versatile 3-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: 250µA at 5V

ꢀ

MULTIPLYING-MODE BANDWIDTH: 350kHz

ꢀ POWER-ON RESET TO ZERO

ꢀ POWER SUPPLY: +2.7V to +5.5V

ENSURED MONOTONIC BY DESIGN

ꢀ

ꢀ SETTLING TIME: 10µs to ±0.003% FSR

The DAC8501 requires an external reference voltage to set

the output range of the DAC. The DAC8501 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 DAC8501 contains a power-down

feature, accessed over the serial interface, that reduces the

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

ꢀ LOW-POWER SERIAL INTERFACE WITH

SCHMITT-TRIGGERED INPUTS

ꢀ ON-CHIP OUTPUT BUFFER AMPLIFIER,

RAIL-TO-RAIL OPERATION

ꢀ SYNC INTERRUPT FACILITY

ꢀ MSOP-8 PACKAGE

The low-power consumption of this part in normal operation

makes it ideally suited to portable battery-operated equip-

ment. The power consumption is 1.2mW at 5V reducing to

1µW in power-down mode.

APPLICATIONS

ꢀ PROCESS CONTROL

The DAC8501 is available in an MSOP-8 package.
