Description

The AD725ARZ is a low-cost general-purpose RGB to NTSC/PAL encoder that is used to convert red, green, and blue color component signals into their corresponding luminance (baseband amplitude) and chrominance (subcarrier amplitude and phase) signals in accordance with either NTSC or PAL standards. This electronic component is categorized under encoders, decoders, and converters. It features TTL logic levels, an integrated delay line, and auto-tuned filters. The AD725ARZ drives 75V reverse-terminated loads and is designed for low power consumption with the ability to power down to less than 1 mA. The product is manufactured by Analog Devices Inc.
