ADS1210U

Analog To Digital Converters (ADC) Overview

The ADS1210U is a precision, low-power analog-to-digital converter manufactured by Texas Instruments. It features a 24-bit resolution and supports data rates up to 16 ksps. The device operates on a single power supply ranging from 4.75 V to 5.25 V. It utilizes a sigma-delta architecture with an internal programmable gain amplifier. The component is housed in an 18-pin Small Outline Package (SOP). It includes an internal reference voltage and clock, reducing external component count. The input stage accepts differential signals, providing high common-mode rejection for accurate signal acquisition in noisy environments.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'U' corresponds to the SOP-18 package variant when sourcing. Confirm that the revision level matches the required input impedance characteristics, as historical data indicates potential variations between manufacturing lots. Ensure compatibility with the intended operating temperature range and power supply specifications before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of high resolution and moderate speed is required without external oscillators or references. Consider the input impedance variability if interfacing with high-impedance sensors; additional buffering may be necessary. Compare against higher-speed ADCs if data rates exceed 16 ksps are needed. Verify that the single-supply voltage range aligns with the system's power architecture.

Analog To Digital Converters (ADC) Part Context

The ADS1210 belongs to Texas Instruments' family of precision sigma-delta analog-to-digital converters. It is designed for applications demanding high accuracy and low noise. The 'U' suffix specifically denotes the plastic small-outline package. This part serves as a foundational component for precision measurement systems where resolution is critical over high-speed throughput.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers include ADS1211, ADS1212, and ADS1213. These variants offer similar architectures but may differ in channel count, data rate, or package options. Verify pinout compatibility and electrical specifications before substitution.
