ILA7050

TECHNICAL DATA ILA7050 LOW VOLTAGE MONO/STEREO POWER AMPLIFIER GENERAL DESCRIPTION The ILA7050 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 R) = 32 Q Vp=3V;dtat=10% D.C. output offset voltage between the outputs Noise output voltage (r.m.s. value) at f = 1 kHz; Rg = 5 kfit Stereo application Output power at R( = 32 Ω dtot = 10%; Vp = 3V dtot = 10%; Vp= 4,5V Vp ltot 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 DIL; plastic (SOT97); SOT97-1; w w w t a .D S a e h PO lAVI U 4 t e .c m o 1,6 typ. typ. max. typ. to 6,0 V 3,2 mA 140 mW 70 mV 140 mV Vno(rms) PO PO K Vno(rms) typ. typ. typ. typ. 35 mW 75 mW 40 dB 100 mV 1 www.DataSheet4U.com ILA7050 CHARACTERISTICS Vp = 3 V; f = 1 kHz; RL = 32 0., Tamb = 25 °C; unless otherwise specified PARAMETER Supply Supply voltage Total quiescent current Bri...
