DESCRIPTION
The DAC8541 is a low-power, single channel, 16-bit,
voltage output DAC. Its on-chip precision output
amplifier allows rail-to-rail voltage swing to be achieved
at the output. The DAC8541 utilizes a 16-bit parallel
interface and features additional powerdown function
pins as well as hardware-enabled, asynchronous DAC
updating and reset capability.
The DAC8541 requires an external reference voltage to
set the output range of the DAC. The device
incorporates a power-on-reset circuit that ensures that
the DAC output powers up at min-scale and remains
there until a valid write takes place to the device. In
addition, the DAC8541 contains a power-down feature,
accessed via two hardware pins, that when enabled
reduces the current consumption of the device to
200 nA at 5 V.
The low power consumption of this device in normal
operation makes it ideally suited for use in portable
battery operated equipment applications. The power
consumption is 1.2 mW at AVDD = 5 V reducing to 1 µW
in power-down mode.
The DAC8541 is available in a 32-lead TQFP package
with an operating temperature range of −40°C to 85°C.
