DESCRIPTION
The DAC8532 is a dual channel, 16-bit Digital-to-Analog
Converter (DAC) offering low power operation and a flexible
serial host interface. Each on-chip precision output amplifier
allows rail-to-rail output swing to be achieved over the supply
range of 2.7V to 5.5V. The device supports a standard 3-wire
serial interface capable of operating with input data clock
frequencies up to 30MHz for V
DD
= 5V.
The DAC8532 requires an external reference voltage to set
the output range of each DAC channel. Also incorporated
into the device is a power-on reset circuit which ensures that
the DAC outputs power up at zero-scale and remain there
until a valid write takes place. The DAC8532 provides a
flexible power-down feature, accessed over the serial inter-
face, that reduces the current consumption of the device to
200nA at 5V.
The low-power consumption of this device in normal opera-
tion makes it ideally suited to portable battery-operated
equipment and other low-power applications. The power
consumption is 2.5mW at 5V, reducing to 1
μ
W in power-
down mode.
The DAC8532 is available in a MSOP-8 package with a
specified operating temperature range of –40
°
C to +105
°
C.
