FUNCTIONAL DESCRIPTION
The TDA2614 is a hi-fi power amplifier designed for mains
fed applications, such as radio and TV. The circuit is
optimally designed for asymmetrical power supplies, but is
also well-suited to symmetrical power supply systems.

An output power of 6 W (THD = 0.5%) can be delivered
into an 8 Ω load with a supply of 24 V. The gain is internally
fixed at 30 dB, thus offering a low gain spread.

A special feature is the input mute circuit. This circuit
disconnects the non-inverting input when the supply
voltage drops below 10 V, while the amplifier still retains its
DC operating adjustment. The circuit features suppression
of unwanted signals at the input, during switch-on and
switch-off.

The mute circuit can also be activated via pin 2. When a
current at 300 µA is present at pin 2, the circuit is in the
mute condition.
The device is provided with two thermal protection circuits.
One circuit measures the average temperature of the
crystal and the other measure the momentary temperature
of the power transistors. These control circuits attack at
temperatures in excess of 150 °C, so a crystal operating
temperature of max. 150 °C can be used without extra
distortion.

Notes to the characteristics
1. VP = 24 V; RL = 8 Ω; Tamb = 25 °C; f = 1 kHz; asymmetrical power supply IMUTE < 30 µA. See Fig.5
2. The power bandwidth is measured at an output power of PO max − 3 dB.
3. The noise output voltage (RMS value) is measured at RS = 2 kΩ, unweighted (20 Hz to 20 kHz).
4. The ripple rejection is measured at RS = 0 and f = 100 Hz to 20 kHz, at a ripple voltage of 200 mV. With symmetrical
power supplies, the ripple (200 mV) is applied in phase to the positive and the negative supply rails.
With asymmetrical power supplies, the ripple rejection is measured at f = 1 kHz.
5. VP = 8 V; RL = 8 Ω; Tamb = 25 °C; f = 1 kHz; asymmetrical power supply. See Fig.5
6. ±VP = 12 V; RL = 8 Ω; Tamb = 25 °C; f = 1 kHz; symmetrical power supply IMUTE < 30 µA. See Fig.4
7. The internal network at pin 2 is a resistor devider of typical 4 kΩ and 5 kΩ to the positive supply rail. At the connection
of the 4 kΩ and 5 kΩ resistor a zener diode of typical 6.6 V is also connected to the positive supply rail. The spread
of the zener voltage is 6.1 to 7.1 V.

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 (Tstg 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.
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.
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.
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.
