ADS8507IDWG4

Analog To Digital Converters (ADC) Overview

The ADS8507IDWG4 is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 40 kSPS and supports both parallel and SPI digital interfaces. The device functions on dual power supplies ranging from 4.75 V to 5.25 V for both analog and digital domains. Key performance metrics include an SNR of 87 dB, SINAD of 89.9 dB, DNL of -2/3 LSB, and INL of +/- 3 LSB. It features an internal oscillator, daisy-chain capability, and selectable external or internal reference inputs. The component 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

• Supports flexible data output via parallel or serial SPI interface modes
• Integrates an internal oscillator and daisy-chain functionality for system expansion
• Allows configuration between external and internal voltage reference sources

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution signal acquisition
• Medical instrumentation utilizing precise analog front-end digitization
• Data acquisition modules in test and measurement equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix G4 against current manufacturer documentation to confirm RoHS compliance status and lead time availability. Confirm that the SOIC-28 package dimensions match the target PCB footprint requirements. Ensure the selected variant aligns with the required operating temperature range and interface protocol specifications for the intended design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution at 40 kSPS is required with flexible interface options. Compare against the ADS8509 if higher speed up to 250 kSPS is needed, noting the pinout differences. Consider the ADS8506 if 12-bit resolution suffices for lower cost applications. Verify power supply constraints match the 5V nominal requirement.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS850x family of high-speed, low-power ADCs from Texas Instruments. The family includes variants like the ADS8505, ADS8506, and ADS8509, which share similar SAR architectures but differ in resolution, speed, and interface configurations. The IDWG4 suffix indicates a specific tape-and-reel or tube packaging option compliant with environmental standards.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8507IDW is the non-G4 version of this component. For higher speed needs, the ADS8509 series offers 250 kSPS performance. The ADS8506 provides a 12-bit alternative. Verify pin compatibility and software driver adjustments when substituting.
