Visão Geral
Description
The HT82V38 is a CMOS image sensor analog front-end (AFE) IC by Holtek, designed for processing signals from CCD or CIS (Contact Image Sensor) devices. It features 8-bit resolution, correlated double sampling (CDS), programmable gain amplifier (PGA), and 10-bit ADC, making it suitable for scanners, copiers, and barcode readers.
Key features include:
- CDS for noise reduction
- PGA with 0dB to 36dB gain
- Internal 10-bit ADC
- Low power consumption (~50mW)
- Single 5V supply
The HT82V38 simplifies signal conditioning and digitization, improving image quality in cost-sensitive applications. Its compact 24-pin SOP package ensures easy integration.
For detailed specs, refer to the Holtek datasheet.
