Technical Specifications

While precise specifications may vary, the UPD6125AG-766 typically functions with a supply voltage ranging from 2.4V to 3.6V. It utilizes an internal oscillator to produce the carrier frequency required for IR signal modulation, usually around 455 kHz. The IC accommodates multiple key inputs and is designed to be compliant with the NEC encoding format, a widely accepted standard in IR remote control communication. The device is generally housed in a small outline package (SOP) to allow for space-saving designs.

The UPD6125AG-766 combines key functions essential for transmitting remote control signals, including scanning key inputs, encoding commands, generating the carrier frequency, and modulating the IR signal. Its low power draw is particularly advantageous for battery-operated remote controls, contributing to an extended operational lifespan. Compatibility with the NEC encoding format ensures effective communication across a diverse array of consumer electronic devices.
