DUAL EQ AMP WITH ALC S1A0241A01
INTRODUCTION
9−SIP
The S1A0241A01 is a monolithic integrated clrcuit consisting of
a dual equalizer amplifier with ALC, and it is suitable for stereo
radio cassette-tape recorders.
FEATURES
• Dual equalizer amplifier with built-in ALC circuit Low
noise; V
• High open loop voltage gain: 80dB (Typ)
• Wide operating supply voltage range:
VCC = 4.5V − 14V
• Good ALC response balance between channels
• Input coupling capacitor unnecessary
• Diode or transistor for ALC unnecessary
• Minimum number of external parts required
= 1.0µV (Typ)
