CXA3668N Datasheet | Sony Semiconductor Solutions

.. 24 pin SSOP (Plastic) Reception Analog Signal Processor IC for Infrared Space Digital Audio munication Description The CXA3668N is an IC that performs reception side analog signal processing for optical munication in bination with an infrared photodiode within a Digital Infrared Audio Transmission (DIAT) system. This IC incorporates a low noise trans-conductance amplifier (I/V amplifier) that converts the optical current from the photodiode into a voltage and amplifies it, an AGC amplifier, a low-pass filter, bandpass filters, and an output amplifier. The band-pass filters are used to separate the desired signal and the interfering signal. This chip has the two types of Full (3 to 6MHz) and Half (3 to 4.5MHz) band-pass filters, and these can be switched according to the application. - Full: Full-band width (3 to 6MHz) - Half: Half-band width (3 to 4.5MHz) Features - Wide dynamic range - On-chip I/V amplifier - On-chip output filter - Filter band switching pin - Surface mounting package (24-pin SSOP) Applications - Infrared headphones - Infrared speakers Structure Bi-CMOS IC...
