PGA2311P Datasheet PDF - TI

●The PGA2311P is a high-performance Stereo Audio Volume Control designed for professional and high-end consumer audio systems. The PGA2311 uses an internal high-performance operational amplifier to yield low noise and distortion. The PGA2311 also provides the capability to drive 660R loads directly without buffering. The 3-wire serial control interface allows for connection to a wide variety of host controllers, in addition to support for daisy-chaining of multiple PGA2311 devices.

● Digitally-controlled analog volume control - Serial control interface and zero crossing detection

● Noise-free level transitions

● Low interchannel crosstalk - 130dBFS

● Power supplies - ±5V analog and +5V digital

● Low noise and distortion - 120dB Dynamic range

● +31.5 to -95.5dB with 0.5dB steps Wide gain and attenuation range

● 150°C Junction temperature

● 100pF Load capacitance stability

● 50mA Short-circuit current

●Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
