FUNCTIONAL DESCRIPTION
The AM circuit incorporates a double balanced mixer, a
one pin low-voltage oscillator (up to 30 MHz) a
field-strength indicator output and is designed for
distributed selectivity.
The AM input is designed to be connected to the top of a
tuned circuit. AGC controls the IF amplification and for
large signals it lowers the input impedance.
The first AM selectivity can be an IFT as well as an IFT
combined with a ceramic filter; the second one is an IFT.
The FM circuit incorporates a tuned RF stage, a double
balanced mixer, a one-pin oscillator, a field-strength
indicator output and is designed for distributed IF ceramic
filters. The FM quadrature detector uses a ceramic
resonator.

The PLL stereo decoder incorporates a signal dependent
stereo circuit, a soft-mute circuit and a stereo indicator
LED driver.
Supply voltage behaviour
The TEA5711 incorporates internal stabilized power
supplies. The maximum supply voltage is 12 V, the
minimum voltage can go down temporarily to 1.8 V without
any loss in performance.
Due to the capacitor at pin 19 (RIPPLE) the IC gives
excellent performance, even when the actual supply
voltage at pin 25 (VP) drops below the voltage at pin 19
(RIPPLE).
Fig.5
Figures 4, 5 and 6 show that Vstab, which is dominant for
the overall IC performance, remains unaffected, even if VP
drops down to 1.8 V or less. In this typical example the
static or average VP is equal to 2.5 V. Dips in Vstab appear
only when the peak-to-peak value of the AC-component of
VP > 2 V, i.e. when the dynamic value of VP drops down to
1.5 V for a short moment.
Supply voltage behaviour; Vripple as a
function of time.

Application remarks
• Short circuiting: all pins are short-circuit proof except pin 16 (FM-RFI) with respect to the supply voltage pin.
• For an example of printed-circuit board layout: see Figs 9 and 10.
• Align VCO with aerial signal present.

SOLDERING
BY SOLDER PASTE REFLOW
Plastic dual in-line packages
Reflow soldering requires the solder paste (a suspension
of fine solder particles, flux and binding agent) to be
applied to the substrate by screen printing, stencilling or
pressure-syringe dispensing before device placement.
BY DIP OR WAVE
The maximum permissible temperature of the solder is
260 °C; this temperature must not be in contact with the
joint for more than 5 s. The total contact time of successive
solder waves must not exceed 5 s.
Several techniques exist for reflowing; for example,
thermal conduction by heated belt, infrared, and
vapour-phase reflow. Dwell times vary between 50 and
300 s according to method. Typical reflow temperatures
range from 215 to 250 °C.
The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified storage maximum. If the printed-circuit board has
been pre-heated, forced cooling may be necessary
immediately after soldering to keep the temperature within
the permissible limit.
Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 min. at 45 °C.
REPAIRING SOLDERED JOINTS (BY HAND-HELD SOLDERING
IRON OR PULSE-HEATED SOLDER TOOL)
REPAIRING SOLDERED JOINTS
Fix the component by first soldering two, diagonally
opposite, end pins. Apply the heating tool to the flat part of
the pin only. Contact time must be limited to 10 s at up to
300 °C. When using proper tools, all other pins can be
soldered in one operation within 2 to 5 s at between 270
and 320 °C. (Pulse-heated soldering is not recommended
for SO packages.)
Apply the soldering iron below the seating plane (or not
more than 2 mm above it). If its temperature is below
300 °C, it must not be in contact for more than 10 s; if
between 300 and 400 °C, for not more than 5 s.
Plastic small-outline packages
BY WAVE
For pulse-heated solder tool (resistance) soldering of VSO
packages, solder is applied to the substrate by dipping or
by an extra thick tin/lead plating before package
placement.
During placement and before soldering, the component
must be fixed with a droplet of adhesive. After curing the
adhesive, the component can be soldered. The adhesive
can be applied by screen printing, pin transfer or syringe
dispensing.
Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder bath is
10 s, if allowed to cool to less than 150 °C within 6 s.
Typical dwell time is 4 s at 250 °C.
A modified wave soldering technique is recommended
using two solder waves (dual-wave), in which a turbulent
wave with high upward pressure is followed by a smooth
laminar wave. Using a mildly-activated flux eliminates the
need for removal of corrosive residues in most
applications.
