ADS1100A1IDBVR

Analog To Digital Converters (ADC) Overview

The ADS1100A1IDBVR is a self-calibrating, 16-bit analog-to-digital converter (ADC) from Texas Instruments. It utilizes a delta-sigma architecture with an integrated programmable gain amplifier (PGA) and internal oscillator. The device supports I2C serial interface communication and accepts differential or single-ended inputs. It operates on a supply voltage range of 2.7 V to 5.5 V for both analog and digital domains. 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. The component is housed in a compact SOT-23-6 surface-mount package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'A1' against the manufacturer's datasheet to confirm the exact gain setting and factory trim values. Ensure the ordering part number matches the required package variant and temperature grade. Cross-reference the manufacturer's official documentation for any recent product change notices that may affect pin compatibility or electrical specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high-resolution 16-bit conversion is required at low data rates. The integrated PGA reduces the need for external amplification circuitry. Verify that the system's I2C bus speed is compatible with the device's clock requirements. Consider the power budget, as the device consumes 270 µW during operation, which is suitable for energy-efficient applications.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS1100 series of precision ADCs. The series offers various gain configurations denoted by the suffix letter. The ADS1100A1IDBVR specifically provides a fixed gain configuration optimized for certain input ranges. It shares the same core architecture and interface protocol with other members of the family, differing primarily in gain settings and factory calibration offsets.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS1100A0IDBVR and ADS1100A2IDBVR are functionally similar parts within the same series. Verify if the gain difference between these variants meets the application requirements before substitution. Other ADS1100 series members may offer different sampling rates or gain options but maintain pin compatibility.
