13.1.1.Description
The LM317T is an adjustable 3 terminal positive voltage regulator capable of supplying in excess of 1.5
amps over an output range of 1.25 to 37 volts. This voltage regulator is exceptionally easy to use and
requires only two external resistors to set the output voltage. Further, it employs internal current limiting,
thermal shutdown and safe area compensation, making it essentially blow–out proof. The LM317
serves a wide variety of applications including local, on card regulation. This device can also be used to
make a programmable output regulator, or by connecting a fixed resistor between the adjustment and
output, the LM317 can be used as a precision current regulator.

The TDA1308 is an integrated class AB stereo headphone driver contained in an SO8 or a DIP8 plastic
package. The device is fabricated in a 1 mm CMOS process and has been primarily developed for
portable digital audio applications. It gets its input from two analog audio outputs (DACA_L and
DACA_R) of MSP 34x0G. The gain of the output is adjustable by the feedback resistor between the
inputs and outputs.

13.3.MSP34X0G (MSP3410G)
13.3.1.Description
The MSP 34x0G family of single-chip Multi standard Sound Processors covers the sound processing of
all analog TV-Standards worldwide, as well as the NICAM digital sound standards. The full TV sound
processing, starting with analog sound IF signal-in, down to processed analog AF-out, is performed on
a single chip. Figure shows a simplified functional block diagram of the MSP 34x0G.

C interaction is
necessary (Automatic Sound Selection).
This new generation of TV sound processing ICs now includes versions for processing the multi
channel television sound (MTS) signal conforming to the standard recommended by the Broadcast
Television Systems Committee (BTSC). The DBX noise reduction, or alternatively, MICRONAS Noise
Reduction (MNR) is performed alignment free. Other processed standards are the Japanese FM-FM
multiplex standard (EIA-J) and the FM Stereo Radio standard. Current ICs have to perform adjustment
procedures in order to achieve good stereo separation for BTSC and EIA-J. The MSP 34x0G has
optimum stereo performance without any adjustments.
All MSP 34x0G versions are pin and software downward compatible to the MSP34x0D. The
MSP34x0G further simplifies controlling software. Standard selection requires a single I
