TEA5591A

GENERAL DESCRIPTION

The TEA5591A is a 24-pin integrated radio circuit, derived from the TEA5591 and is designed for use in AM/FM portable

radios and clock radios. The TEA5591A differs from the TEA5591 in that it has:

• Separate IF input pins for AM and FM

• A split-up AM-IF stage (for distributed selectivity)

• An LED driver indicator

The main advantage of the TEA5591A is its ability to operate over a wide range of supply voltages (1.8 to 15 V) without

any loss of performance.

The AM circuit incorporates:

• A double balance mixer

• A ‘one-pin’ oscillator with amplitude control operating in the 0.6 to 30 MHz frequency range

• A split-up IF amplifier

• A detector

• An AGC circuit which controls the IF amplifier and mixer.

The FM circuit incorporates:

• An RF input amplifier

• A double balanced mixer

• A ‘one-pin’ oscillator

• Two IF amplifiers (for distributed selectivity)

• A quadrature demodulator for a ceramic filter

• Internal AFC

Features

• LED AM/FM indicator

• A DC AM/FM switch facility

• Three separate stabilizers to enable operation over a wide range of supply voltages (1.8 to 15 V)

• All pins (except pin 10) are ESD protected

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.
