2.1
Overview
The TDA 5100A is a single chip ASK transmitter for the frequency band 433-
435 MHz. The IC offers a high level of integration and needs only a few external
components. The device contains a fully integrated PLL synthesizer and a high
efficiency power amplifier to drive a loop antenna. A special circuit design and
an unique power amplifier design are used to save current consumption and
therefore to save battery life. Additional features like a power down mode, a low
power detect and a divided clock output are implemented.
