CXA1821M Description

Short technical summary and product information.

The CXA1821M is an integrated circuit developed by Sony Corporation specifically for use in compact disc players. This IC features an APC (Automatic Power Control) circuit, along with RF, focus error, and tracking error amplifiers, making it suitable for 3-spot optical pickup outputs.

 

Key features include low power consumption of 40mW at ±2.5V, compatibility with both single (+5V) and dual (±2.5V) power supply operations, and support for RF amplification at double speed. The device is compatible with pickups for LC and PD systems.

 

Constructed as a bipolar silicon monolithic IC, the CXA1821M is housed in a 20-pin SOP (Plastic) package. It operates within a temperature range of -20°C to +75°C and has an absolute maximum supply voltage of 12V. The allowable power dissipation is 600mW at 25°C.

 

This RF amplifier is ideal for applications within compact disc players, providing essential signal processing for optical pickup systems.
