DUAL LOW NOISE EQUALIZER AMPLIFIER S1A2221A02
INTRODUCTION
The S1A2221A02 is a monolithic integrated circuit consisting of
a 2-channel pre-amplifier in a 8-pin plastic single in line package. The minimum operating voltage is 2.5V, Making it suitable
for low voltage application.
FEATURES
• Wide operating supply voltage: VDD = 2. 5V − 6V
• Low noise (V
= 1.0µV: Typ)
HI
• High channel separation
• Good ripple rejection ratio
• Minimum number of external parts required
