ADS1110A2IDBVT

Overview

The ADS1110A2IDBVT is a high-precision, 16-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It is designed for applications requiring low power consumption and high accuracy, such as sensor interfaces, portable instrumentation, and industrial control systems. The device integrates a voltage reference and a programmable gain amplifier, simplifying system design and reducing component count. The ADC operates over a wide supply voltage range and features an I2C interface for easy integration with microcontrollers and other digital systems. Its small form factor (SOT-23 package) makes it suitable for space-constrained applications. The ADS1110A2IDBVT is widely used in medical devices, environmental monitoring, and consumer electronics due to its reliability and performance.

The ADS1110A2IDBVT consists of a delta-sigma ADC core, a voltage reference, and a programmable gain amplifier (PGA). The delta-sigma architecture ensures high resolution and noise immunity, making it ideal for precision measurements. The integrated voltage reference provides stable performance across temperature variations, while the PGA allows for signal amplification up to 8x. The device operates by sampling the analog input signal, converting it to a digital value through the ADC core, and transmitting the result via the I2C interface. The conversion process is controlled by an internal oscillator, ensuring consistent timing. The ADS1110A2IDBVT also includes a power-down mode to reduce energy consumption when not in use.

B2B Procurement Guide

When procuring the ADS1110A2IDBVT, consider factors such as lead time, supplier reliability, and pricing. Verify the supplier's credentials and ensure they are authorized distributors of Texas Instruments products to avoid counterfeit components. Bulk purchases may offer cost savings, but evaluate storage conditions to prevent damage. Check for compliance with industry standards, such as RoHS and REACH, to meet environmental regulations. Request samples for testing before large-scale orders to confirm compatibility with your application. Compare prices from multiple suppliers, keeping in mind that the reference price range is approximately $3.50 to $5.00 per unit, depending on quantity and market conditions.
