Description
The CXA1600M/P is an 8-pin single-chip bipolar IC
for AM radios. This IC includes all functions from
the front-end to the power amplifier.
The CXA1600M/P doesn’t require any external
filter, making external ceramic filter attachment
unnecessary.
Features
• EIAJ output=100 mW (typ.)
(VCC=3 V, RL=8 Ω)
• Built-in electrical volume control.
• No ceramic filter required.
• Few peripheral components.
