ADS8885IDGSR

Analog To Digital Converters (ADC) Overview

The ADS8885IDGSR is a single-channel, 18-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a maximum sampling rate of 400 kSPS and features truly differential analog inputs. The device requires an analog supply voltage ranging from 2.7 V to 3.6 V and a digital supply voltage between 1.65 V and 3.6 V. It utilizes an external reference and communicates via an SPI interface. Key performance metrics include a signal-to-noise ratio of 100 dB and a signal-to-noise and distortion ratio of 99.9 dB. Power consumption is specified at 2.6 mW. The component is housed in a 10-lead MSOP package and supports operation within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Supports daisy-chaining for multi-channel system expansion
• Integrates an internal oscillator to reduce external component count
• Provides high-resolution data conversion with low power dissipation

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation
• Industrial process control systems
• Battery-powered measurement devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging configuration, as indicated by the 'R' designation. Ensure compatibility with moisture sensitivity level requirements during storage and handling. Confirm that the external reference voltage matches the ADC input specifications for optimal accuracy. Validate that the PCB footprint aligns with the MSOP-10 package dimensions provided in the official datasheet.

Analog To Digital Converters (ADC) Selection Notes

Select this model when an 18-bit resolution and 400 kSPS throughput are required in a compact form factor. Compare against the ADS8885IDRCR if a smaller VSON-10 package is preferred over the MSOP-10 variant. Consider the ADS8887IDGS if a lower sampling rate of 100 kSPS suffices for reduced power consumption. Ensure the application can accommodate the need for an external voltage reference rather than an integrated one.

Analog To Digital Converters (ADC) Part Context

This component belongs to the Texas Instruments microPOWER™ family of SAR ADCs. It shares architectural similarities with the ADS8881 and ADS8887 series, differing primarily in sampling speed and power characteristics. The IDGSR suffix denotes the industrial temperature range and MSOP-10 package with reel packaging. It serves as a high-precision alternative to lower-resolution devices in the ADS886x series.

Analog To Digital Converters (ADC) Replacement Considerations

ADS8885IDRCR offers identical electrical performance in a VSON-10 package. ADS8887IDGS provides similar resolution but at a reduced 100 kSPS rate. ADS8881IDGS delivers higher speed at 1 MSPS with increased power consumption.
