DESCRIPTION
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.
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.
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 1
W
in power-down mode.
The DAC8531 is available in both MSOP-8 and 3x3 SON-8
(same size as QFN) packages.
