ta8262h TOSHIBA Semiconductor CORPORATION, ta8262h Datasheet - Page 3

• Manufacturer Part Number: ta8262h
• Description: Max Power 43 W Btl X 4ch Audio Power Ic
• Manufacturer: TOSHIBA Semiconductor CORPORATION

Caution and Application Method
1. Voltage gain adjustment
This IC has no NF (negative feedback) terminals. Therefore, the voltage gain can't adjusted, but it makes
the device a space and total costs saver.
Therefore, the total voltage gain is decided by expression below.
The voltage gain of Amp. 1
The voltage gain of Amp. 2A, B
The voltage gain of BLT Connection : G
