ADS1100A1IDBVT

Analog To Digital Converters (ADC) Overview

The Texas Instruments ADS1100A1IDBVT is a self-calibrating, 16-bit delta-sigma analog-to-digital converter (ADC) housed in a compact SOT-23-6 surface-mount package. It features a single differential or single-ended input channel and communicates via an I2C serial interface. The device operates on a supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. Key electrical specifications include a maximum sampling rate of 128 samples per second, a power consumption of 270 µW, and an integral nonlinearity (INL) of 8.2 LSB. It functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated programmable gain amplifier (PGA) with selectable address options
• Built-in internal oscillator eliminates the need for external clock components
• Self-calibrating architecture ensures high accuracy without manual offset adjustments

Analog To Digital Converters (ADC) Applications

• Battery-powered portable instrumentation due to low power consumption
• Industrial process control systems requiring precise signal acquisition
• Medical devices needing high-resolution data conversion in small form factors

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IDBVT indicates the tape-and-reel packaging format when ordering. Confirm that the A1 grade meets the required performance specifications for your application. Ensure compatibility with the I2C bus protocol used in the target system design before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and low sampling rate are sufficient for the application. Consider the SOT-23-6 package constraints for PCB layout. Verify that the I2C interface aligns with the microcontroller capabilities. Evaluate if the integrated PGA and self-calibration features reduce the need for external precision components.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS1100 series of low-power, high-precision ADCs from Texas Instruments. The series includes variants such as the ADS1100A0 and ADS1100A2, which share similar core architectures but may differ in factory calibration grades or specific pin configurations. The ADS1100A1IDBVT represents a specific configuration optimized for general-purpose high-resolution applications.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADS1100A0IDBVT and ADS1100A2IDBVT. These parts share identical pinouts and functional blocks but may have different factory-trimmed accuracy grades. Verify that the replacement part's INL and offset drift specifications meet the original design requirements.
