ADS8881IDGSR

Analog To Digital Converters (ADC) Overview

The ADS8881IDGSR is a single-channel, 18-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It operates with a maximum sampling rate of 1 MSPS and features a true differential input architecture. The device utilizes an SPI-compatible serial interface for data transfer. Power consumption is specified at 5.5 mW under typical operating conditions. It supports an analog supply voltage range of 2.7 V to 3.6 V and a digital I/O supply range of 1.65 V to 3.6 V. The component requires an external voltage reference within the 2.5 V to 5 V range. It is housed in a 10-lead MSOP package and functions across an industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Daisy-chainable architecture allows multiple devices to be connected on a single serial bus for expanded system capability.
• Integrated internal oscillator eliminates the need for external clock sources, simplifying board design.
• Small physical footprint provided by the compact MSOP-10 package suitable for space-constrained applications.

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation requiring high resolution and low power consumption
• Industrial process control systems utilizing differential signal inputs
• Data acquisition modules in battery-operated equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IDGSR against the official datasheet to confirm the reel packaging variant. Ensure the ordering part number matches the required temperature grade and package type. Cross-reference the manufacturer's latest documentation for any updates regarding moisture sensitivity levels or recommended soldering profiles before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 18-bit resolution and 1 MSPS throughput are required in a single-channel configuration. Compare power dissipation metrics against similar SAR ADCs if battery life is critical. Confirm that the external reference voltage range aligns with the available system supplies. Evaluate the daisy-chain feature if multiple converters are needed in the final design.

Analog To Digital Converters (ADC) Part Context

The ADS8881IDGSR belongs to the microPOWER™ family of SAR ADCs from Texas Instruments. This series emphasizes low power consumption while maintaining high precision. The IDGSR suffix denotes the tape-and-reel packaging format, distinct from the tube-packaged IDGS variant. It shares architectural similarities with other members like the ADS8885 and ADS8887, differing primarily in sampling speed and power specifications.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8881CDGSR serves as a commercial-grade alternative with a limited temperature range of 0°C to 70°C. For lower-speed applications, the ADS8885IDGSR offers 400 kSPS performance with reduced power consumption. The ADS8887IDGSR provides 100 kSPS operation with even lower power usage. All these parts share the same MSOP-10 package and pinout compatibility.
