ADS1110A0IDBVR

Analog To Digital Converters (ADC) Overview

The ADS1110A0IDBVR is a precision, continuous self-calibrating analog-to-digital converter (ADC) featuring a delta-sigma architecture and a single differential input channel. It provides 16-bit resolution with no missing codes and supports data rates of 15, 30, 60, or 240 samples per second. The device integrates a 2.048V internal voltage reference, enabling a ±2.048V differential input range, and includes a programmable gain amplifier (PGA) with gains of 1, 2, 4, or 8. It operates on a single supply voltage ranging from 2.7V to 5.5V and communicates via an I2C-compatible serial interface. Packaged in a compact SOT-23-6 form factor, it is designed for low-power applications.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-precision 2.048V internal voltage reference and a programmable gain amplifier to support small signal measurements without external components.
• Features a continuous self-calibration mechanism that minimizes offset and gain errors over time and temperature variations.
• Supports multiple data rate options to balance conversion speed and power consumption, including a single-shot mode for ultra-low standby current.

Analog To Digital Converters (ADC) Applications

• Portable battery-powered instrumentation requiring high accuracy and minimal power draw
• Industrial process control systems utilizing smart transmitters
• Precision measurement nodes in distributed sensor networks

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'A0' indicates the default I2C address configuration as documented in the official datasheet. Confirm the package type matches the required PCB footprint, specifically the SOT-23-6 variant. Ensure the operating environment falls within the specified industrial temperature range of -40°C to +125°C. Check for RoHS compliance status if environmental regulations apply to the final assembly. Validate supply voltage levels against the 2.7V to 5.5V operational limits.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-resolution ADC is needed in a space-constrained design. The integrated PGA allows direct connection to low-level sensors, reducing bill-of-materials count. Compare data rates against system latency requirements, as the maximum speed is 240 SPS. Consider the I2C address constraints if multiple devices share the same bus, noting that the 'A0' suffix defines the base address. Evaluate power budgets carefully, as the device offers significant current savings in single-shot modes compared to continuous conversion.

Analog To Digital Converters (ADC) Part Context

This part belongs to the Texas Instruments ADS1110 family of delta-sigma ADCs. It shares architectural similarities with the ADS1100 but offers higher sampling rates and additional features like the internal oscillator and broader temperature range. The 'DBVR' suffix denotes the surface-mount SOT-23-6 package with tape-and-reel packaging, distinguishing it from the 'DBVT' tray version. It serves as a drop-in replacement for legacy 16-bit ADCs in compact designs.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS1110A0IDBVT is a pin-compatible alternative with identical electrical characteristics, differing only in the reel versus tray packaging format. Other ADS1110 variants with different address suffixes may require software address adjustments. Cross-family replacements like the ADS1115 offer additional channels but differ in package and interface capabilities.
