ADS1100A4IDBVR

Analog To Digital Converters (ADC) Overview

The ADS1100A4IDBVR is a self-calibrating, 16-bit analog-to-digital converter (ADC) from Texas Instruments. It utilizes a sigma-delta architecture with an integrated programmable gain amplifier (PGA) and internal oscillator. The device supports I2C digital interfaces 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 specifications 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 SOT-23-6 package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated self-calibration capability eliminates the need for external calibration components.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'A4' against the manufacturer datasheet to confirm the fixed gain setting and address configuration. Ensure the ordering part number matches the required reel quantity and tape-and-reel specifications. Cross-reference the date code and RoHS compliance status with current inventory records to guarantee material consistency.

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 stages. Verify that the system interface supports the standard I2C protocol and that the supply voltage remains within the 2.7 V to 5.5 V operational window.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS1100 series of precision ADCs. Variants within the series differ primarily by their fixed PGA gain settings and I2C slave addresses. The ADS1100A4IDBVR specifically denotes a version with a defined gain configuration and address code, packaged in a small-outline transistor format suitable for surface mount assembly.

Analog To Digital Converters (ADC) Replacement Considerations

Compatible substitutes include other ADS1100 variants with different gain/address codes, such as ADS1100A0IDBVR or ADS1100A1IDBVT, provided the gain and address requirements are met. The ADS1110 series offers similar functionality but includes an internal reference and higher sampling rates.
