ADS8509IDWG4

Analog To Digital Converters (ADC) Overview

The ADS8509IDWG4 is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a single-ended input and supports a sampling rate of 250 kS/s via an SPI serial interface. The device 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 (SNR) of 88 dB, differential nonlinearity (DNL) of +/- 2 LSB, and integral nonlinearity (INL) of +/- 3 LSB. It is housed in a 20-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 ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature rating. Confirm RoHS compliance status through current datasheets as specifications may be updated. Cross-reference the component marking code with the official package outline drawing to validate authenticity and physical dimensions before integration into production designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 250 kSPS throughput are required for single-ended signals. Ensure the system design accommodates the 4.75 V to 5.25 V supply requirement. Consider the 20-SOIC package dimensions for PCB layout constraints. Verify that the SPI interface timing aligns with the host microcontroller capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8509 series of high-speed, low-power ADCs from Texas Instruments. It shares architectural similarities with other members of the family but differs in pin count and package options. The IDWG4 suffix specifically denotes the industrial temperature range and the 20-lead SOIC package variant.

Analog To Digital Converters (ADC) Replacement Considerations

Check for ADS8509IDW as a potential equivalent if the G4 suffix indicates a specific manufacturing revision or environmental compliance update. Verify pin compatibility and electrical parameters against the latest datasheet before substitution.
