Product Overview
The ADS1216Y/2K is a 24-bit delta-sigma ADC designed for high-precision measurement equipment. It supports 8 differential or 8 single-ended input channels, integrates a programmable gain amplifier, 2.5V reference and excitation current sources to simplify sensor circuit design. Equipped with 4-wire SPI interface and on-chip RAM for calibration data, this industrial-grade ADC works from -40°C to 85°C, supplied in 2000pcs tape reel TQFP packaging.
Core Advantages
High Resolution & Low Distortion
24-bit lossless conversion with typical INL of ±0.0015% FS, stable sampling up to 780SPS for tiny sensor signal capture.
All-In-One Analog Frontend
Built-in 1~128x PGA, multi-channel MUX, 2.5V voltage reference and programmable IDAC current sources, greatly reducing external components.
Flexible Digital Design
Standard SPI bus supports daisy chain connection; on-chip RAM stores user calibration parameters, with 8 GPIO pins for peripheral control.
Wide Industrial Compatibility
2.7V~5.25V dual analog/digital supply, -40℃~85℃ operating temperature, fully RoHS compliant for industrial and medical equipment.

Frequently Asked Questions
Q1: Is ADS1216Y/2K 100% original TI stock?
A: All goods are brand new original TI components, complete batch quality inspection, shipped with factory anti-static tape reel packaging.
Q2: What does suffix /2K stand for?
A: /2K means 2000 pieces per standard tape reel, optimized for automated SMT production lines.
Q3: Why integrated PGA and reference are important for sensors?
A: Weak millivolt sensor signals are amplified internally, built-in reference eliminates external precision components to reduce circuit noise and PCB size.
Q4: Can analog and digital power rails use the same voltage?
A: Yes, both AVDD and DVDD support 2.7V~5.25V supply, you can use unified power rail or separate power supply for better anti-interference performance.
Q5: Can I order small samples before bulk purchase?
A: Sample orders from 1 piece are supported, we can provide short delivery samples for your prototype testing.
Q6: What is the warranty period of this ADC chip?
A: We offer 1-year quality warranty for all ADS1216Y series products against factory defects.
Q7: How fast can you ship out my order after payment?
A: In-stock items will be shipped within 1-2 working days after payment confirmation.
Q8: Is this chip compatible with RTD and strain gauge sensors?
A: Yes, the built-in IDAC excitation current sources perfectly match RTD, thermocouple and load cell signal acquisition.
Q9: What should I do if I need a large bulk quotation?
A: Submit your BOM list via the inquiry form, we will provide competitive bulk pricing within 24 hours.
