TDA7050T

INTEGRATED CIRCUITS DATA SHEET TDA7050T Low voltage mono/stereo power amplifier Product specification File under Integrated Circuits, IC01 July 1994 Philips Semiconductors Product specification Low voltage mono/stereo power amplifier GENERAL DESCRIPTION TDA7050T 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 V No external components required Very low quiescent current Fixed integrated gain of 26 dB, floating differential input Flexibility in use − mono BTL as well as stereo Small dimension of encapsulation (see package design example). QUICK REFERENCE DATA Supply voltage range Total quiescent current (at VP = 3 V) Bridge tied load application (BTL) Output power at RL = 32 Ω VP = 3 V; dtot = 10% D.C. output offset voltage between the outputs Noise output voltage (r.m.s. value) at f = 1 kHz; RS = 5 kΩ Stereo application Output power at RL = 32 Ω dtot = 10%; VP = 3 V dtot = 10%; VP = 4,5 V Channel separation at RS = 0 Ω; f = 1 kHz Noise output voltage (r.m.s. value) at f = 1 kHz; RS = 5 kΩ PACKAGE OUTLINE 8-lead mini-pack; plastic (SO8; SOT96A); SOT96-1; 1996 July 24.
