Product Overview
The VSP2582RHNR is a highly integrated, 12-bit Analog Front End (AFE) made by Texas Instruments for high-speed, high-resolution CCD and CMOS image sensor signal processing. It supports sampling speeds up to 36MSPS and integrates the full analog signal conditioning circuit on a single chip. Its internal modules include input clamp circuit, high precision CDS to suppress reset noise, digital-controlled PGA, and 12-bit SAR ADC. It also has black level calibration and built-in voltage reference to reduce peripheral components. Packaged in small heat-conductive VQFN-36, this low-power chip fits digital cameras, flatbed scanners, medical endoscopes and surveillance cameras.
Core Advantages
Superior 36MSPS Image Capturing Rate
Supports 12-bit high-speed sampling up to 36MSPS, enabling smooth high frame rate capture and fast data processing for line or area image sensors.
Integrated Correlated Double Sampling (CDS)
Onboard CDS circuit removes kTC reset noise and low-frequency interference from image sensors to improve signal-to-noise ratio of output images.
Wide-Range Digitally Programmable Gain
Built-in PGA adjustable via serial bus, allowing main controller to adjust signal gain dynamically to adapt to different lighting environments.
Ultra-Compact, Low-Power Imaging Design
Integrates multiple analog signal processing circuits into one chip, simplifies PCB layout, reduces equipment volume and lowers overall power consumption.

Frequently Asked Questions
Q1: Is your VSP2582RHNR stock 100% original?
A: All VSP2582RHNR AFE ICs we supply are brand new original TI parts. We store and ship products with standard ESD and moisture-proof packaging.
Q2: What function does the integrated CDS module realize?
A: CDS samples sensor signal twice at reset level and signal level, subtracts two values to eliminate kTC noise and extract effective pixel signal to improve image quality.
Q3: Does VSP2582RHNR need external reference voltage for 12-bit conversion?
A: No. The chip integrates stable internal voltage reference matched with its ADC, removing the need for external reference chips and simplifying peripheral circuit design.
Q4: How to get reflow data, register configuration and bulk quotation?
A: Fill out the inquiry form on this page with your engineering demands. Our technical team will send complete technical documents and wholesale price within 24 hours.
