It may be used in a wide array of professional and consumer audio equipment. The PGA2310 is fabricated in a mixed-signal BiCMOS process, as to take advantage of the superior analog characteristics for which it offers. The heart of the PGA2310 is a resistor network, an analog switch array, and a high-performance bipolar op amp stage. The switches are used to select taps in the resistor network that, in turn, determine the gain of the amplifier stage. Switch selections are programmed using a serial control port. The serial port allows connection to a wide variety of host controllers. Figure 1 shows a functional block diagram of the PGA2310. POWER-UP STATE On power up, all internal flip-flops are reset. The gain byte value for both the left and right channels are set to 00HEX, or mute condition. The gain will remain at this setting until the host controller programs new settings for each channel via the serial control port. ANALOG INPUTS AND OUTPUTS The PGA2310 includes two independent channels, referred to as the left and right channels. Each channel has a corresponding input and output pin. The input and output pins are unbalanced, or referenced to analog ground (either AGNDR or AGNDL). The inputs are named VINR (pin 9) and VINL (pin 16), while the outputs are named VOUTR (pin 11) and VOUTL (pin 14). The input and output pins may swing within 1.5V of the analog power supplies, VA+ (pin 12) and VA− (pin 13). Given VA+ = +15V and VA− = −15V, the maximum input or output voltage range is 27VPP. It is important to drive the PGA2310 with a low source impedance. If a source impedance of greater than 600 Ω is used, the distortion performance of the PGA2310 will begin to degrade.
