General Description
The TDA5101A is a single chip
Package
ASK transmitter for the frequency band
315 MHz. The IC offers a high level of
integration and needs only a few exter-
nal components. The device contains a
fully integrated PLL synthesizer and a 0.5
high efficiency power amplifier to drive ^0.22±0.05
a loop antenna. A special circuit design
