FEATURES
GENERAL DESCRIPTION
• Requires very few external components
• No switch-on/switch-off clicks
The TDA2615 is a dual power amplifier in a 9-lead plastic
single-in-line (SIL9MPF) medium power package. It has
been especially designed for mains fed applications, such
as stereo radio and stereo TV.
• Input mute during switch-on and switch-off
• Low offset voltage between output and ground
• Excellent gain balance of both amplifiers
• Hi-fi in accordance with “IEC 268” and “DIN 45500”
• Short-circuit proof and thermal protected
• Mute possibility.

FUNCTIONAL DESCRIPTION
The TDA2615 is a hi-fi stereo amplifier designed for mains
fed applications, such as stereo radio and stereo TV. The
circuit is optimally designed for symmetrical power
supplies, but is also well-suited to asymmetrical power
supply systems.

An output power of 2 × 6 W (THD = 0.5%) can be
delivered into an 8 Ω load with a symmetrical power supply
of ±12 V. The gain is internally fixed at 30 dB, thus offering
a low gain spread and a very good gain balance between
the two amplifiers (0.2 dB).

A special feature is the input mute circuit. This circuit
disconnects the non-inverting inputs when the supply
voltage drops below ±6 V, while the amplifier still retains its
DC operating adjustment. The circuit features suppression
of unwanted signals at the inputs, during switch-on and
switch-off.
The mute circuit can also be activated via pin 2. When a
current of 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 measures 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.

1. For asymmetrical power supplies (with the load short-circuited), the maximum unloaded supply voltage is limited to
VP = 28 V and with an internal supply resistance of RS ≥ 4 Ω, the maximum unloaded supply voltage is limited to 32 V
(with the load short-circuited). For symmetrical power supplies the circuit is short-circuit-proof up to VP = 21 V.

Notes
1. VP = ±12 V; RL = 8 Ω; Tamb = 25 °C; fi = 1 kHz; symmetrical power supply IMUTE = < 30 µA (see Fig.4).
2. The power bandwidth is measured at a maximum output power (POmax) of −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 fi = 100 Hz to 20 kHz. The ripple voltage (200 mV) is applied in phase
to the positive and the negative supply rails. With asymmetrical power supplies, the ripple rejection is measured at
fi = 1 kHz.
5. ±VP = 4 V; RL = 8 Ω; Tamb = 25 °C; fi = 1 kHz; symmetrical power supply (see Fig.4).
6. VP = 24 V; RL = 8 Ω; Tamb = 25 °C; fi = 1 kHz; asymmetrical power supply IMUTE < 30 µA (see Fig.5).
7. The internal network at pin 2 is a resistor divider 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.
