ADS1115IDGST

Analog To Digital Converters (ADC) Overview

The ADS1115IDGST is a 16-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a sigma-delta architecture and features four differential or two single-ended input channels via an internal multiplexer. The device supports I2C digital interfaces with programmable gain amplifier (PGA) settings. It operates on a digital power supply ranging from 2 V to 5.5 V and achieves sampling rates up to 860 S/s. Key electrical parameters include a gain error of 0.01% and integral nonlinearity (INL) of 1 LSB. The component is housed in a 10-VSSOP package and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IDGST corresponds to the 10-VSSOP package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the supplier provides valid traceability data for the Texas Instruments manufacturing origin. Cross-reference the ordering part number against current distributor catalogs to confirm availability and correct packaging type.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring high resolution in a compact surface-mount footprint. The 16-bit resolution and low noise characteristics suit precision sensor interfacing. Consider the I2C interface compatibility with the host microcontroller. Evaluate the operating temperature range requirements against the specified -40°C to +125°C limit for the intended environment.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS111x family of 16-bit ADCs, which are designed as industry-leading small-footprint solutions. The ADS1115 specifically provides four input channels, distinguishing it from lower-channel variants like the ADS1113 or ADS1114. It represents a performance upgrade over previous embedded ADC generations with faster sampling capabilities.

Analog To Digital Converters (ADC) Replacement Considerations

Compatible substitutes within the same family include ADS1114 and ADS1113, though these offer fewer input channels. Other ADS111x variants may share pinouts but differ in channel count or package options. Verify functional equivalence regarding PGA settings and I2C addressing before substitution.
