ADS8507IDWRG4

Analog To Digital Converters (ADC) Overview

The ADS8507IDWRG4 is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a maximum sampling rate of 40 kSPS and supports both parallel and serial SPI interfaces. The device functions on a single 5V supply, accepting input voltages between 4.75V and 5.25V for both analog and digital domains. Key performance metrics include an SNR of 87 dB and a SINAD of 89.9 dB. Differential nonlinearity is specified at -2/3 LSB, while integral nonlinearity is +/- 3 LSB. It is housed in a 28-pin SOIC package and operates within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Applications

• Industrial process control systems
• Data acquisition modules
• Medical instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RG4' indicates RoHS compliance and tape-and-reel packaging when sourcing. Confirm the manufacturer is Texas Instruments and the base part number is ADS8507. Ensure the package type matches the required 28-pin SOIC footprint for PCB layout compatibility.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring 16-bit resolution at moderate speeds up to 40 kSPS. Consider the available parallel or SPI interface based on system bus constraints. Verify that the single-ended input configuration meets the signal source requirements before finalizing the design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8507 family of high-speed, low-power ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS8508 and ADS8509 but differs in sampling speed and pin count. The IDW suffix denotes the industrial temperature range and SOIC package variant.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8507IDW is a tube-packaged equivalent with identical electrical characteristics. The ADS8509 offers higher speed but uses a different 20-pin package. Verify pinout compatibility before substituting.
