ADS1100A2IDBVT

Analog To Digital Converters (ADC) Overview

The ADS1100A2IDBVT is a 16-bit delta-sigma analog-to-digital converter (ADC) from Texas Instruments, housed in a compact 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 2.7V to 5.5V and supports serial I2C communication interfaces. Key electrical parameters include a resolution of 16 bits, a maximum sampling rate of 128 samples per second (SPS), and an operating temperature range from -40°C to +85°C. The component includes self-calibration capabilities and offers optional address selection for multi-device systems.

• Medical equipment such as pulse oximeters and blood pressure monitors
• Weight scales and force measurement platforms

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'A2' indicates the fixed internal gain setting when ordering. Confirm the 'DBVT' suffix corresponds to the SOT-23-6 tape-and-reel packaging format. Ensure compatibility with the target I2C bus voltage levels within the 2.7V to 5.5V operational range. Check for RoHS compliance status if required by regional regulations.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a fixed gain configuration is sufficient for the application signal range. Compare against other ADS1100 variants with different gain settings if higher sensitivity is needed. Consider the 128 SPS maximum data rate against system bandwidth requirements. Verify that the I2C address options meet the addressing constraints of the host microcontroller.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS1100 series of precision ADCs designed for low-cost, high-resolution applications. It shares architectural similarities with the ADS1101 but differs in feature sets such as PGA availability. The series targets applications replacing traditional bridge sensors where size and power efficiency are critical constraints.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include other ADS1100 variants with different gain codes (e.g., ADS1100A0, ADS1100A1) if gain adjustments are permissible. Cross-reference with ADS1101 models if additional features like internal reference or different pinouts are acceptable.
