AD8801AN

Overview

The AD8801AN is an 8-channel, 8-bit Digital-to-Analog Converter (DAC) manufactured by Analog Devices Inc. It features a trim DAC architecture with power shutdown capability and operates on a single supply voltage ranging from 3 V to 5 V for both analog and digital domains. The device utilizes a 3-Wire or SPI-compatible serial interface for data input. Key electrical specifications include a settling time of 600 ns, a differential nonlinearity (DNL) of ±0.25 LSB, and an integral nonlinearity (INL) of ±0.5 LSB. It is housed in a 16-lead SOIC package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• 8-channel 8-bit resolution with external reference requirement
• 3-Wire/SPI compatible serial interface
• Power shutdown mode for energy efficiency
• ±0.25 LSB DNL and ±0.5 LSB INL accuracy

Applications

• Battery-powered instrumentation systems
• Industrial process control loops
• Programmable gain amplifiers and filters

Procurement Notes

Verify the specific suffix 'AN' against official Analog Devices documentation, as standard listings often use 'ARZ'. Confirm current lifecycle status, as similar models may be obsolete. Ensure the external reference voltage matches the required output swing. Check RoHS compliance details for the specific manufacturing batch.

Selection Notes

Select this component when multiple low-cost, moderate-speed voltage outputs are required. The 8-bit resolution limits precision applications; higher bit counts are needed for tighter tolerance requirements. The external reference design adds complexity but allows for optimized noise performance. Verify that the 600 ns settling time meets the system's update rate requirements.

Part Context

The AD8801 belongs to the AD8801 family of multi-channel DACs. It shares architectural similarities with other Analog Devices trim DACs but is distinct in its 8-channel configuration and 8-bit resolution. It serves as a cost-effective solution for applications requiring multiple analog outputs without the need for high-speed conversion.

Replacement Considerations

Check for direct pin-to-pin replacements within the AD8801 series. Consider the AD8802 for higher resolution if speed permits. Verify compatibility with existing PCB footprints and thermal management solutions when substituting.
