ADS1100A2IDBVR

Analog To Digital Converters (ADC) Overview

The ADS1100A2IDBVR is a 16-bit delta-sigma analog-to-digital converter (ADC) from Texas Instruments, housed in a 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 I2C serial communication. Key electrical parameters include a resolution of 16 bits, a maximum sampling rate of 128 samples per second, and an operating temperature range of -40°C to 85°C. The component includes self-calibration capabilities to maintain accuracy without external reference components.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'A2' against the official datasheet to confirm the fixed internal gain setting. Ensure the ordering part number matches the required package variant and tape-and-reel specifications. Cross-reference the manufacturer's latest documentation to confirm RoHS compliance status and lead times before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high-resolution 16-bit conversion is required within a minimal footprint. The integrated PGA reduces external component count compared to non-amplified ADCs. Verify that the I2C address configuration meets system requirements, as the A2 suffix may dictate a specific hardware address setting distinct from other variants in the series.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS1100 family of ultra-small, low-power ADCs. It shares architectural similarities with the ADS1100A0 and ADS1100A1 but differs in its fixed gain configuration. The SOT-23-6 packaging allows for space-constrained designs common in portable electronics and compact industrial sensors.

Analog To Digital Converters (ADC) Replacement Considerations

ADS1100A0IDBVR: Offers different gain settings; verify address compatibility. ADS1100A1IDBVR: Alternative gain option within the same package. ADS1110A4IDBVR: Higher sampling rate but different temperature range.
