... Connecting the load resistor to ground and operating from a single supply, the outputs swing completely to ground without saturating. The outputs can also drive to within 1.2V of the top rail. The EL2257 will output ±100mA and will operate with single supply voltages as low as 2.7V, making them ideal for portable, low power applications. ...

... FIGURE 8. Multiplexing with the EL2257 The ENABLE pins on the EL2257 allow for multiplexing applications. Figure 9 shows an EL2257 with both outputs tied together, driving a back terminated 75: video load. Two sinewaves of varying amplitudes and frequencies are applied to the two inputs. Logic signals are applied to each of the ENABLE pins to cycle through turning each of the amplifiers on, one at a time ...
