ADS8508IBDWRG4

Analog To Digital Converters (ADC) Overview

The ADS8508IBDWRG4 is a single-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 250 kSPS and supports both single-ended and differential input configurations. The device features an internal oscillator and reference, alongside an external reference option. It communicates via a standard SPI-compatible serial interface. Power supply requirements include 4.75 V to 5.25 V for both analog and digital domains. Key performance metrics include a signal-to-noise ratio of 73 dB, integral nonlinearity of +/- 0.45 LSB, and differential nonlinearity of +/- 0.45 LSB. It functions within a temperature range of -40°C to +85°C and is housed in a 20-pin SOIC package.

Analog To Digital Converters (ADC) Feature Summary

• Integrated internal oscillator eliminates the need for external clocking components.
• Supports daisy-chaining capabilities for multi-channel system expansion.
• Offers flexible reference configuration options including internal and external sources.

Analog To Digital Converters (ADC) Applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging versus tube packaging for the base model. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering part number matches the required package variant and temperature grade for your specific design implementation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit resolution with 250 kSPS speed is required. Consider the internal oscillator feature if board space for external clocks is limited. Verify that the 5V supply voltage aligns with your system's power architecture and that the SOIC-20 package fits your PCB layout constraints.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS8508 family of high-speed, low-power ADCs from Texas Instruments. It is designed for applications demanding moderate resolution with high throughput. The IBDW suffix denotes the industrial temperature range and SOIC package type, while the G4 indicates lead-free and RoHS compliant construction.

Analog To Digital Converters (ADC) Replacement Considerations

ADS8508IBDW serves as the tube-packaged equivalent. ADS8506 offers lower speed at 40 kSPS but retains similar resolution. Check datasheets for pin compatibility and electrical parameter overlaps before substituting.
