BIPOLAR ANALOG INTEGRATED CIRCUIT uPC1238V,4PC1238H T-74-05-01

10 W AF POWER AMPLIFIER

‘The pPC1238 is an audio power amplifier designed for median Hi-Fi stereo set and TV set sound power amplifier. ‘The ¢PC1238 incorporates the thermal protection circuit to protect the damage of IC chip against load damping etc. ‘Since the package is a 6 Pin TO-220 package, it greatly simplifies construction of a power amplifier both in design and as- ‘sembly.

FEATURES

© High output power © Low equivalent input noise voltage. 8.4 W TYP. (at 8 2, Voc =#13 V) © Available for NFB tone control mode. 12.5 W TYP. {at 4 2, Voc = #13 V) © Negligible power ON/OFF noise. © Low THD. © High density components assembly due to 5 Pin 70-220 package. 0.012 % TYP. (Pout =2 W, Ry =8 2) 0.02 % TYP.
