Micropower Operation: 250 µA at 5 V AV  
Power-On Reset to Min-Scale  
16-Bit Monotonic  
DD  
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.  
Settling Time: 10 µs to 0.003% FSR  
16-Bit Parallel Interface  
On-Chip Output Buffer Amplifier With  
Rail-to-Rail Operation  
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.  
Hardware Reset to Min-Scale or Mid-Scale
