HEADPHONE OUTPUT

TDA1308

The TDA1308 is an integrated class AB stereo headphone driver. It gets its input from two analog audio outputs (DACA_L

and DACA_R) of MSP3410D. The gain of the output is adjustable by the feedback resistor between the inputs and outputs.

Features:

Wide temperature range

No switch ON/OFF clicks

Excellent power supply ripple rejection

Low power consumption

Short-circuit resistant

High performance

- high signal-to-noise ratio

- high slew rate

- low distortion

Large output voltage swing

Pinning:

1. Output A (Voltage swing) : Min : 0.75V, Max : 4.25V

2. Inverting inputA

: Vo(clip) : Min : 1400mVrms

3. Non-inverting inputA

: 2.5V

4. Ground

5. Non-inverting input B

: 2.5V

6. Inverting input B

: Vo(clip) : Min : 1400mVrms

7. Output B (Voltage swing) : Min : 0.75V, Max : 4.25V

8. Positive supply

: 5V, Min : 3.0V, Max : 7.0V

AUDIO OUTPUT

TDA7265

The TDA7265 is a 25W+25W stereo sound amplifier with mute/stand-by facility. STPAcontrol signal coming from microcontroller

(when it is at high level) activates the mute function. IC is muted when mute port is at low level. Two stereo audio signals

coming from audio module is injected to the inputs of the IC and a power of 12Wrms (10%) is obtained. An external pop-

noise circuitry pulls AF inputs of the IC in order to eliminate pop noise when TV is turned on or off via mains supply

connection. It is possible to adjust the gain of the amplifiers by feedback external resistors.

Features:

n Wide supply voltage range (up to 50V ABS Max.)

n Split supply

n High output power: 25+25 W @ TDA = 10%, RL = 8ohm, VS = ±20V

n No pop at turn-on / off

n Mute (pop free)

n Stand-By feature (low IQ)

n Few external components

n Thermal overload protection

n Adjustable gain via an external resistor
