ADS1100A3IDBVRG4

Analog To Digital Converters (ADC) Overview

The ADS1100A3IDBVRG4 is a 16-bit delta-sigma analog-to-digital converter (ADC) from Texas Instruments, housed in a SOT-23-6 package. It features a single differential or single-ended input channel with an integrated programmable gain amplifier (PGA). The device operates on a supply voltage ranging from 2.7 V to 5.5 V and supports I2C serial communication. Key electrical parameters include a maximum sampling rate of 128 samples per second, a power consumption of 270 µW, and an integral nonlinearity (INL) of 8.2 LSB. It functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' indicates compliance with RoHS directives and halogen-free standards as per Texas Instruments documentation. Confirm the package type matches the required PCB footprint. Ensure the operating environment stays within the specified -40°C to +85°C temperature range for reliable performance.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and low power consumption are critical for sensor interfaces. The integrated PGA reduces external component count compared to non-PGA variants. Verify that the I2C address configuration meets system requirements, as different suffixes may offer selectable addresses.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS1100 family of low-power, 16-bit ADCs. It shares architectural similarities with the ADS1100A0, A1, and A2 variants, differing primarily in PGA gain settings and I2C addressing options. The G4 suffix typically denotes environmental compliance enhancements over earlier revisions.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include other ADS1100 variants such as ADS1100A0IDBVR or ADS1100A1IDBVR, provided the PGA gain and I2C address configurations align with the design requirements. Cross-referencing the datasheet for pin compatibility and electrical specifications is essential before substitution.
