Frequently Asked Questions
What is the resolution and number of output channels of the DAC8568IAPW?
The DAC8568IAPW provides 16-bit resolution across 8 independent voltage output channels, enabling precise analog signal generation with a minimum LSB size of approximately 38µV at a 2.5V reference with 2x gain (5V full-scale output).
What interface does the DAC8568IAPW use and does it support daisy-chaining?
The DAC8568IAPW uses a 3-wire SPI-compatible serial interface operating up to 50MHz. It supports daisy-chain operation via the SDOUT pin, allowing multiple devices to be cascaded on a single SPI bus to expand the number of analog output channels without additional chip-select lines.
What supply voltage does the DAC8568IAPW require, and what package does it come in?
The DAC8568IAPW operates from a 2.7V to 5.5V single supply, making it compatible with both 3.3V and 5V systems. The device is available in a 20-pin TSSOP (PW) package, suitable for space-constrained PCB designs.
Does the DAC8568IAPW have an internal voltage reference?
Yes, the DAC8568IAPW includes an internal 2.5V voltage reference with a selectable 2x gain buffer, providing a 5V full-scale output range. An external reference can also be applied for applications requiring different output spans or higher accuracy.
What are the typical applications for the DAC8568IAPW?
Typical applications include industrial process control with multiple analog set-points, automatic test equipment requiring precision multi-channel stimulus, medical instrumentation, programmable power supplies, motor control offset adjustment, and optical transceiver bias control where simultaneous independent channel updates are needed.
