ELECTRICAL CHARACTERISTICS
Pre–Amplifier/Expander/R x Mute/Volume Control (See Figure 4)
operational amplifier with the non–inverting input terminal
connected to the internal V B half supply reference. External
resistors and capacitors can be connected to set the gain and
frequency response. The expander analog ground is set to
(Test Conditions: V CC = 2.6 V, T A = 25 C, f in = 1.0 kHz, Set External Pre–Amplifier R’s for Gain of 1, Volume Control = (0111).)

capability will increase as the supply voltage increases. The
volume control can be adjusted through the MPU interface.
The “R x Audio In” input signal is ac coupled.
