P3017
The P3017 is an audio power amplifier designed for portable systems with low power consumption. When a 5V power supply is applied to the P3017, it delivers 2W RMS power into 3-W loads. When 0.7 W RMS power is delivered into 8-W load, P3017 has less than 0.5% THD+N in the specified operation frequency range.
The supply current only consumes as low as 6mA during normal operation and 150uA when in the shutdown mode. The embedded-pop circuit also eliminates pop noise and frees up board space.
Gain is controlled by two digital terminals, Gain0 & Gain1, for 4 steps gain setting (6dB, 10dB, 15.6dB, 21.6dB).
P3312
The P3312 is an audio power amplifier designed for portable system with low power consumption. When 5V power supply is applied on P3212, it delivers 2.1W RMS power into 3-W loads. When 1 W RMS power is delivered into 8-W load, P3212 has less than 0.5% THD+N in specified operation frequency range. The supply current only consumes as low as 10mA during normal operation and 150uA when in the shutdown mode. The embedded-pop circuit also eliminates pop noise and frees up board space. The HP/ terminal can control MUX input regardless whether the device is used in single-ended (SE) or bridge-tied load (BTL) mode. The operation mode of the device is decided by the SE/BTL terminal. In BTL mode, Gain is controlled by two digital terminals, Gain0 and Gain1, for 4 steps Gain setting ( 6dB , 10dB , 15.6dB , 21.6dB ). In SE mode, the Gain setting is always 4.1 dB.
