1 3 POWER SUPPLIES AND ANALOG GROUND
The MF8 can be operated from single or dual-polarity power
supplies For dual-supply operation the analog ground (pin
4) should be connected to system ground When single sup-
plies are used pin 4 should be biased to V
The input signal should be dc biased to mid-supply or capacitor-coupled to the input pin
FIGURE 4 Single supply operation The AGND pin must be biased to mid-supply
