GENERAL DESCRIPTION

Features

The TEA5582, a 20-pin integrated phase-locked loop

(PLL) stereo decoder, is designed primarily for low cost

stereo decoding in a low- to medium-line TV. The MUX

input (pin 1) is a low impedance current input, the gain of

the input amplifier is therefore determined by the external

resistor R1 (see Fig.5). All characteristics are measured

with R1 = 47 kΩ. The de-emphasis of (L, R) and (L-R) can

be chosen by means of external capacitors and resistors.

The supply voltage range of the device is from 7 V to 16 V.

• Wide supply voltage range

• Automatic mono/stereo switching (pilot presence

detector)

• LED driver for stereo indicator

• Smooth mono/stereo control

• Matrix and two amplifiers for left and right output signals

• A source selector to switch between the MUX signal and

an external signal

• Mute circuit for 60 dB muting of the output level

• External de-emphasis control of (L, R) and (L − R)

• 6 dB fixed attenuation of (L − R) with respect to (L + R)

prior to matrix

• All pins are protected against Electrostatic Discharge

(ESD)

SOLDERING

Introduction

There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and

surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for

surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often

used.

This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our

“IC Package Databook” (order code 9398 652 90011).

Soldering by dipping or by wave

The maximum permissible temperature of the solder is 260 °C; solder at this temperature must not be in contact with the

joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds.

The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the

specified maximum storage temperature (T_{stg max}). 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.

Repairing soldered joints

Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more

than 2 mm above it. If the temperature of the soldering iron bit is less than 300 °C it may remain in contact for up to

10 seconds. If the bit temperature is between 300 and 400 °C, contact may be up to 5 seconds.
