ADS1100A4IDBVT

Analog To Digital Converters (ADC) Overview

The ADS1100A4IDBVT 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 2.7 V to 5.5 V and supports serial I2C-compatible interfaces. Key electrical parameters include a maximum sampling rate of 128 samples per second, an integral nonlinearity (INL) of 8.2 LSB, and low power consumption of 270 µW at typical operating conditions. The component functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a self-calibrating 16-bit delta-sigma ADC architecture for high precision.
• Includes an onboard programmable gain amplifier to accommodate various signal levels.
• Utilizes a small SOT-23-6 footprint suitable for space-constrained designs.
• Supports standard I2C digital interface for simplified system integration.

Analog To Digital Converters (ADC) Applications

• Battery-powered portable instrumentation
• Industrial process control sensors
• Medical monitoring devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'A4' corresponds to the required PGA gain setting and I2C address configuration before procurement. Confirm that the SOT-23-6 thermal characteristics meet the application's heat dissipation requirements. Ensure the selected distributor provides genuine Texas Instruments components with traceable lot codes to maintain quality standards.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 16-bit resolution and low data rate are sufficient for the application. Compare against the ADS1110 series if a higher sampling rate or wider industrial temperature range (-40°C to +125°C) is required. Verify that the internal reference type matches the system design, as this variant utilizes a supply-referenced internal reference rather than an external pin.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS1100 family of low-power, high-precision ADCs. It shares architectural similarities with the ADS1110 but differs in sampling speed and temperature specifications. The part is designed for applications requiring minimal external components while maintaining accuracy in noisy environments.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS1110A4IDBVT serves as a functional alternative with increased sampling rates and extended temperature ranges. Verify compatibility regarding PGA settings and I2C addressing when substituting these models.
