RF Amplifier for CD Players

CXA1821M

Description

The CXA1821M is an IC developed for compact

disc players. This IC incorporates an APC circuit and

RF, focus error, and tracking error amplifiers for 3-

spot optical pickup output. (The voltage-converted

optical pickup output is supported.)

20 pin SOP (Plastic)

Features

• Low power consumption (40mW at ±2.5V)

• APC circuit

• Both single power supply (+5V) and dual power

supply (±2.5V) operations possible.

• Compatible with pickup for LC and PD

• Supports the RF amplifier at double speed.
