CXA1600M/P
8-pin Single-chip AM Radio with Built-in Power Amplifier
For the availability of this product, please contact the sales office.
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.
