DAC8541Y/250

The DAC8541Y/250 is a low-power 1-channel 16-bit voltage output Digital-to-analog Converter (DAC) with 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 power-down 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 200nA at 5V. The low power consumption of this device in normal operation makes it ideally suited for use in portable battery operated equipment applications.
