Low voltage mono/stereo power amplifier

GENERAL DESCRIPTION
The TDA7050T is a low voltage audio amplifier for small radios with headphones (such as watch, pen and pocket radios) in mono (bridge-tied load) or stereo applications.
Features
Limited to battery supply application only (typ. 3 and 4 V)Operates with supply voltage down to 1,6 VNo external components requiredVery low quiescent currentFixed integrated gain of 26 dB, floating differential inputFlexibility in use − mono BTL as well as stereoSmall dimension of encapsulation (see package design example).Circuit Diagram

TDA1308 Class-AB stereo headphone driver

General description:
The TDA1308 is an integrated class-AB stereo headphone driver contained in an SO8 or  a TSSOP8 plastic package. The device is fabricated in a 1 μm Complementary Metal  Oxide Semiconductor (CMOS) process and has been primarily developed for portable digital audio applications.
Features and benefits:
Wide temperature rangeNo switch ON/OFF clicksExcellent power supply ripple rejectionLow power consumptionShort-circuit resistantHigh performanceHigh signal-to-noise ratioHigh slew rateLow distortionLarge output voltage swingCircuit diagram:
