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) ltot typ. 3,2 mA Bridge tied load application (BTL) Output power at R) = 32 Q Vp=3V;dtat=10% PO typ. 140 mW D.C. output offset voltage between the outputs lAVI max. 70 mV Noise output voltage (r.m.s. value) at f = 1 kHz; Rg = 5 kfit Vno(rms) typ. 140 mV Stereo application Output power at R( = 32 Ω dtot = 10%; Vp = 3V PO typ. 35 mW dtot = 10%; Vp= 4,5V PO typ. 75 mW Channel separation at Rs = 0 Ω ; f = 1 kHz K typ. 40 dB Noise output voltage (r.m.s. value) at f = 1 kHz; Rs = 5 kΩ Vno(rms) typ. 100 mV PACKAGE OUTLINE 8-lead DIL; plastic (SOT97); SOT97-1;
