Features
- Uses fewer external components.
- No need for FM IFT, AM IFT, and FM detector coil
- Adjustment free for FM detector circuit
- Wide operating supply voltage range, 1.8V to 7V
This IC is available in DIP16 or SOP16 packages, pictures below.

Example circuits
Here you can find a complete project on this IC, simple FM receiver circuit with TA2003P. This project requires just few external parts and it can can be operated from a 3 volt power supply.
There are few reference circuit provided in the datasheet, I'm posting some of them.
A tested FM receiver circuit.
You can find more about the above circuit in the previous link.
Now a dual band AM and FM receiver circuit, as described by the datasheet, tuned via a ganged condenser.
Use the circuit above to check a fm transmitter circuit, like in the link.
Hi
Can/will you drop the other shoe and publish an AM only Design
Taking things to a new level I am building some Steampunk TRF Radios; Antique/Vintage Components, Variometers Variocouplers Variable Condenser/Coil Assemblies with modern electronics.
Can the CD 2003GP Chip be configured as a two RF Stage TRF Receiver
