This circuit make use of the bridge-tied load (BTL) principle to achieve low-voltage operation without sacrifice of output power ,The circuit operates with battery supplies from 6V down to 1.6V ,and draws low quiescent current (typically 3.2mA with 3-V supply).Closed-loop voltage gain is 32dB with connections, as shown (floating differential input ,3-Vsupply and 32-Ω load).Output is reduced to 0.14 when supply is reduced to 3V (with 32-Ω load).
