DUAL PRE-POWER AMP WITH VOLUME CONTROLLER S1A0136A01
1
INTRODUCTION
The S1A0136A01 is a monolithic intergrated circuit designed
for use in low voltage and low power applications. It has functions including dual audio pre-power amplifier, electronic volume controller and DC motor speed controller in a single chip.
It is suitable for portable tape recorders headphone cassette
tape recorders or radios that are battery-operated.
FEATURES
• Low current consumption in an operating voltage range
• Operating supply voltage range: Vcc = 2.1V − 5V
• Only a few components in composing a headphone cassette
tape recorder
• Dual audio pre-power amplifier, electronic volume controller
and DC motor speed controller in a single chip
• Reduced input and output coupling capacitors because of 1/2
Vcc AMP adoption on chip as AC GND
