The CXA1821M is an integrated circuit developed by Sony Corporation specifically for compact disc players. This IC incorporates an APC 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 and the ability to operate with either a single power supply (+5V) or a dual power supply (±2.5V). It is compatible with pickups for LC and PD and supports RF amplification at double speed.
The device is constructed using a bipolar silicon monolithic IC structure and comes 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.
Applications for the CXA1821M are primarily in compact disc players, where its specialized amplification capabilities contribute to the optical pickup system's performance.
