ADS1100A4IDBVRG4

Analog To Digital Converters (ADC) Overview

The ADS1100A4IDBVRG4 is a self-calibrating, 16-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a sigma-delta architecture and features an integrated programmable gain amplifier (PGA). The device supports I2C digital interfaces and accepts differential or single-ended inputs. It operates on analog and digital supply voltages ranging from 2.7 V to 5.5 V. Key electrical specifications include a sampling rate of 128 S/s, a maximum integral nonlinearity (INL) of 8.2 LSB, and a typical power consumption of 270 µW. The component is housed in a compact SOT-23-6 surface-mount package and functions within a commercial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the G4 suffix indicates lead-free compliance and RoHS conformity as per Texas Instruments standards. Confirm the specific tape-and-reel quantity matches project requirements. Ensure the I2C address configuration aligns with system bus constraints. Validate that the operating voltage range covers the target application's supply variations.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high resolution and low power are critical. The internal oscillator simplifies design compared to external clock variants. Consider the PGA settings for signal conditioning needs. Verify interface compatibility with the host microcontroller's I2C controller.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS1100 family of precision ADCs. It shares architectural similarities with the ADS1110 but differs in sampling rates and reference types. The DBVR package variant is optimized for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS1100A4IDBVT is a pin-compatible alternative available in cut-tape packaging. The ADS1110 series offers higher sampling rates but uses an internal reference instead of supply-based referencing.
