ADS1100A6IDBVR

Analog To Digital Converters (ADC) Overview

The ADS1100A6IDBVR is a precision, continuously self-calibrating 16-bit delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It features a fully differential input stage and an onboard programmable gain amplifier (PGA) with selectable gains of 1, 2, 4, or 8. The device operates on a single power supply ranging from 2.7V to 5.5V and utilizes an I²C-compatible serial interface for communication. It supports data rates of 8, 16, 32, or 128 samples per second. The component is housed in a compact SOT-23-6 package and is designed for applications requiring high resolution with minimal space and power consumption.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with no missing codes and integral nonlinearity of 0.0125% of FSR max
• Continuously self-calibrating system compensates for offset and gain errors without user intervention
• Onboard PGA offers gains of 1, 2, 4, or 8 to accommodate small signal measurements
• Low noise performance with typical output noise of 4 µVp-p

Analog To Digital Converters (ADC) Applications

• Portable instrumentation
• Industrial process control
• Smart transmitters
• Temperature measurement

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific I²C address variant when ordering, as the 'A6' suffix denotes a factory-set address distinct from other ADS1100 variants. Confirm that the tape and reel packaging quantity matches the required production volume. Ensure the operating temperature range of –40°C to +85°C aligns with the target application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a fixed I²C address different from the default A0 variant is required to avoid bus conflicts in multi-device systems. Consider the input impedance characteristics, which vary with the PGA setting, when designing input filtering networks. Verify that the ratiometric reference configuration using the power supply is suitable for the sensor source impedance.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS1100 family of self-calibrating ADCs. The primary distinction between variants within this family is the factory-programmed I²C slave address. The ADS1100A6IDBVR shares identical electrical specifications, pinout, and functionality with other ADS1100 models, differing only in its unique device address on the I²C bus.

Analog To Digital Converters (ADC) Replacement Considerations

Other ADS1100 variants (e.g., ADS1100A0IDBVR through ADS1100A7IDBVR) are functionally equivalent but possess different I²C addresses. Substitution requires ensuring the new address does not conflict with existing devices on the bus or updating the master controller's addressing scheme accordingly.
