Audio Switch
TEA6422D
The TEA6422 switches 6 stereo audio inputs on 3 stereo
outputs.
All the switching possibilities are changed through the I2C
BUS.
D023
Headphone AMP
TDA1308T
The TDA1308; TDA1308A is an integrated class AB stereo
headphone driver contained in an SO8, DIP8 or a TSSOP8
plastic package. The device is fabricated in a 1 mmCMOS
process and has been primarily developed for portable digital
audio applications.
The difference between the TDA1308 and the TDA1308A is
that the TDA1308A can be used at low supply voltages.
Analogue Part (Voltage Regulation)
D031
Audio DAC
UDA1334ATS
The UDA1334ATS is a single chip 2 channel digital-to-analog
converter employing bit stream conversion techniques,
including an on-board PLL. The extremely low power
consumption and low voltage requirements make the device
eminently suitable for use in low-voltage low-power portable
digital audio equipment which incorporates a playback function.
D032
Voltage Regulator
LD1117DT33
The LD1117 is a LOW DROP Voltage Regulator able to provide
up to 800mA of Output Current, available even in adjustable
version (Vref=1.25V). Concerning fixed versions, are offered
the following Output Voltages: 1.2V,1.8V,2.5V,2.85V, 3.0V 3.3V
and 5.0V.
D090
DC/DC converter
LT1940EFE
The LT®1940 is a dual current mode PWM step-down DC/DC
converter with internal 2A power switches. Both converters are
synchronized to a single 1.1MHz oscillator and run with
opposite phases, reducing input ripple current. The output
voltages are set with external resistor dividers, and each
regulator has independent shutdown and soft-start
circuits. Each regulator generates a power-good signal when
its output is in regulation, easing power supply sequencing and
interfacing with micro controllers and DSPs.

DC/DC converter
LT1940EFE
D096
step down regulator
L5973D
The L5973D is a step down monolithic power switching
regulator with a minimum switch current limit of 2.5A so it is
able to deliver more than 2A DC current to the load depending
on the application conditions.The output voltage can be set
from 1.235V to 35V.
D0910
Voltage regulator
LD1117DT50
The LD1117 is a LOW DROP Voltage Regulator able to provide
up to 800mA of Output Current, available even in adjustable
version (Vref=1.25V). Concerning fixed versions, are offered
the following Output Voltages: 1.2V,1.8V,2.5V,2.85V, 3.0V 3.3V
and 5.0V.
