ADS8507IDW

Analog To Digital Converters (ADC) Overview

The ADS8507IDW 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 accepts single-ended inputs and functions within an analog and digital supply voltage range of 4.75 V to 5.25 V. Key performance metrics include a signal-to-noise ratio of 87 dB and a signal-to-noise and distortion ratio of 89.9 dB. Differential nonlinearity is specified at -2/3 LSB, while integral nonlinearity is +/- 3 LSB. The component is housed in a 28-pin SOIC package and operates across a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IDW' confirms the SOIC-28 package and industrial temperature grade (-40°C to +85°C). Ensure compatibility with 5V logic levels for the parallel or SPI interface. Confirm RoHS compliance status through the manufacturer's current documentation before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 40 kSPS speed are required for single-ended signals. Consider the ADS8507IDW over higher-speed variants if power consumption and cost are primary constraints. Verify that the 28-pin SOIC footprint fits the PCB layout requirements compared to other package options in the series.

Analog To Digital Converters (ADC) Part Context

The ADS8507IDW belongs to the ADS8507 family of high-performance SAR ADCs from Texas Instruments. This series is designed for applications requiring precise analog-to-digital conversion with moderate throughput. The IDW suffix specifically denotes the wide-body SOIC package variant suitable for surface-mount assembly.

Analog To Digital Converters (ADC) Replacement Considerations

Check for ADS8507IDWR as a reel-based alternative within the same family. Verify pinout and electrical specifications against similar 16-bit SAR ADCs from other manufacturers if sourcing constraints exist.
