Philips Semiconductors Product specification Low voltage mono/stereo power amplifier TDA7050 GENERAL DESCRIPTION
The TDA7050 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 VP 1,6 to 6,0 V Total quiescent current (at VP = 3 V) Itot typ. 3,2 mA
Bridge tied load application (BTL)
Output power at RL = 32 Ω VP = 3 V; dtot = 10% Po typ. 140 mW D.C. output offset voltage between the outputs |∆V| max. 70 mV Noise output voltage (r.m.s. value) at f = 1 kHz; RS = 5 kΩ Vno(rms) typ. 140 µV
Stereo application
Output power at RL = 32 Ω dtot = 10%; VP = 3 V Po typ. 35 mW dtot = 10%; VP = 4,5 V Po typ. 75 mW Channel separation at RS = 0 Ω; f = 1 kHz α typ. 40 dB Noise output voltage (r.m.s. value) at f = 1 kHz; RS = 5 kΩ Vno(rms) typ. 100 µV
