Description
The TDA7570 is a switchmode Power audio amplifier with differential inputs and PWM output.
The maximum output current and voltage swing are depending by the output circuitry (Power Supply, external Power transistors and sensing resistors). The device can work as a stereo single-ended channels or a mono bridge Power amplifier.

Features
■ Output Power 2 x 70W / 1 x 250w @ THD<1%
■ PWM output
■ ±30V Supply voltage (Max)
■ Stand-by
■ Mute
■ Protections against short circuit across the load
■ Chip thermal protection
■ External temperature sensor possibility
■ Thermal warning pins
■ Adjustable clip detector pin

GENERAL DESCRIPTION
The TA0103A is a 250w continuous average (4Ω), two channel Amplifier Driver Module which uses Tripath’s proprietary Digital Power Processing (DPP™) technology. Class-T amplifiers offer both the audio fidelity of Class-AB and the Power efficiency of Class-D amplifiers.

General Description
ML2002 (COG) LCD driver can be cascaded to increase the number of segments drive, with Static driving it can form a single piece of 48 (1 ICs) or 96 (2 ICs cascaded) segments driver. With 1/2 Duty, the number of segment drive would be doubled. It targets at custom TN LCD COG Module product which requires the best quality of TN LCD technology and small to medium number of segment display. ML2002 series driver offers the best contrast, the widest viewing angle, the widest range of operating voltage and temperature when compared to the high duty cycle driver. EMI and Noise protection circuit has been added which tailor made for COG application.

Features
● A Gold Bump Chip which can reduce pin count and area.
● Simplest design with no chargepump to Supply high voltage to LCD
● Only 5 pin is needed which can reduce space.
● Low operating current
● Can disable internal clock to reduce current.
● Wide Logic & LCD Power Supply: 2.5V to 6.0V
● No need to add external voltage regulator
● Static or 1/2 Duty driving with 1/2 Bias
● Number of segments: (Static) 48, (1/2 Duty) 96
● Cascading structure to increase the number of driving segments, it’s more flexible for different application.
● Build-in LCD voltage driver, crystal oscillator, internal RC oscillator and display control circuit.
● Offer best contrast and widest viewing angle of TN LCD technology especially in static mode.
● No temperature compensationis needed for Topr = -40°C to 80°C.

Application
◆ General Purpose Clock
◆ High quality instrument
◆ Telephone, mobile phone
◆ Automotive
◆ Handheld Device like PDA, MP3, or PMP
