Frequently Asked Questions
What is the resolution and accuracy of DAC7641?
The DAC7641 provides 16-bit resolution with ±1 LSB maximum integral nonlinearity (INL) and ±0.5 LSB maximum differential nonlinearity (DNL), guaranteeing monotonic operation. This level of accuracy is suitable for precision instrumentation and ATE applications.
What interface does DAC7641 use?
The DAC7641 uses a 16-bit parallel data bus interface with write (WR) and chip select (CS) control signals. Data is loaded in a single 16-bit write cycle, enabling fast update rates suitable for waveform generation and servo control applications.
Does DAC7641 have an internal reference?
Yes, the DAC7641 includes an internal 2.5V precision reference. An external reference can also be used for higher accuracy or special voltage ranges. The internal reference provides ±5mV initial accuracy with 15ppm/°C temperature coefficient.
What output configurations does DAC7641 support?
The DAC7641 supports both unipolar (0 to VREF) and bipolar (±VREF) output configurations using external op-amp connections. The voltage output buffer provides rail-to-rail swing with 5µs settling time to 16-bit accuracy.
