TUA 4310XS

Circuit Description

The TUA 4310X has been designed as integrated tuner with strictly symmetrical

RF-parts for use in car radios. In addition the IC provides a prestage control and an IF

post amplification.

The IC is especially suitable for use in car radios with prestage control and distributed

IF-selection.

The integrated circuit includes an 2-pin oscillator with symmetrical input, buffered output

and a double balanced mixer for frequency conversion. The RF-input stage allows

symmetrical and unsymmetrical operation. The resulting IF is amplified in a first linear

IF-driver with adjustable gain and in a second IF-driver with an adjustable temperature

coefficient. Between these drivers an additional IF-selection is recommended. The

AGC-stage integrated for prestage control can drive PIN-Diodes as well as MOSFET’s.

The IC also includes a reference voltage source with high supply voltage ripple rejection.
