Additional Details

The TW9990-BATB-GR operates from a single 3.3V power supply. The adaptive contrast enhancement (ACE) feature dynamically adjusts the contrast of the image to improve visibility in both bright and dark areas. The 10-bit ADCs provide high-resolution conversion of the analog video signal, resulting in accurate color reproduction. The device is designed to meet the demanding requirements of automotive and surveillance applications. The I2C interface allows for easy configuration and control of various parameters, enabling fine-tuning of the video output.
