TDA7808

High efficiency digital input automotive quad power amplifier, ’start

stop’ compatible

Datasheet - production data

Description

TDA7808 is a single chip quad bridge amplifier in

advanced BCD technology integrating: a full D/A

converter, digital input for direct connection to I S

(or TDM) and powerful MOSFET output stages.

The integrated D/A converter allows the

performance to reach an outstanding 115 dB S/N

ratio with more than 110 dB of dynamic range.

Moreover TDA7808 integrates an innovative high

efficiency concept, optimized also for

uncorrelated music signals. The device is

designed to be compatible to battery modulation

for class-G systems.

Features

 AEC-Q100 qualified

 24-bit digital processing

 115 dB dynamic range (A-weighted)

Thanks to this concept, the dissipated output

power under average listening conditions can be

reduced up to 50% when compared to the

conventional class AB solutions.

 SB-I (SB - improved) high efficiency operation

the highest ’non - class D’ efficiency

 High output power capability:

– 4 x 27 W 4Ω@ 14.4 V, 1 kHz, THD = 10%

TDA7808 integrates also a programmable PLL

that is able to lock at the input frequencies of

64*Fs for all the input configurations.

 Flexible mode control:

– Full I C bus driving 1.8 V/3.3 V) with four

addresses selectable (only for PowerSO36

package option)

– Independent front/rear play/ mute

– Selectable digital gains for very-low noise

line-out function

TDA7808 is able to play music down to 6 V supply

voltage - so it is compatible with the so called

'start stop' battery profile recently adopted by car

makers (thus reducing the fuel consumption and

the impact over the environment).

 Start-stop compatibility (operation down to 6 V)
