CA0023AN
Video isolation amplifier IC■ Product summary
CA0023AN is a video isolation amplifier that transmits video signals from external equipment to internal
circuit after removing external noise.
Its compact package (SON-8p) with integrated two circuits allows downsizing and cost cut of circuits.
Because a wide operating temperature range is guaranteed, the IC is optimum for video signal interfaceof vehicle equipment.

・Be sure to connect 0.1μF bypass capacitor to between power supply terminals in order to lower theimpedance of a power supply line.
・Bypass capacitor should consider pattern of Printed Circuit to be able to arrange to near the IC
・This IC cannot drive 75Ω directly. When driving 75Ω, connect a video driver IC behind this IC.
・Be sure to connect SW1 and SW2 to VIN side while measuring CMRR.
・Be sure to open the voltage of the backside die-pad, or connect the die-pad to GND. Please don’t use
the connection with GND as an electrode except in case making short-circuit with 6-pin.
