Product specification
TDA8540
FUNCTIONAL DESCRIPTION
The TDA8540 is controlled via a bidirectional I2C-bus.
3 bits of the I2C address can be selected via the address
pin, thus providing a facility for parallel connection of
7 devices.
Control options via the I2C-bus:
The input signals can be clamped at their negative peak
(top sync).
The gain factor of the outputs can be selected between
1× or 2×.
Each of the four outputs can individually be connected
to one of the four inputs.
Each output can individually be set in a high impedance
state.
Two binary output data lines can be controlled for
switching accompanying sound signals.
The SDA and SCL pins (pins 19 and 18) can be connected
to the I2C-bus or to DC switching voltage sources. Address
inputs S0 to S2 (pins 11, 7 and 5) are used to select
sub-addresses or switching to the non-I2C mode. Inputs
S0 to S2 can be connected to the supply voltage (HIGH) or
the ground (LOW). In this way no peripheral components
are required for selection.

I2C-bus control
After power-up the outputs are initialized in the high
impedance state, and D0 and D1 are at a LOW level.
Detailed description of the I2C-bus specification, with
applications, is given in brochure “The I2C-bus and how to
use it”. This brochure may be ordered using the code
9398 393 40011.
The TDA8540 is a slave receiver and the protocol is given
in Table 2.

Notes
1. S = START condition.
2. Data transmission to the TDA8540 starts with the slave address (SLV).
3. A = acknowledge bit, generated by TDA8540.
4. P = STOP condition.
