Low distortion ratio : THD=0.02% (typ)
Low noise : V_no = 0.16 Vrms (typ) (V_CC = 18V, RL = 8 , Rg = 0 , BW = 20 Hz~20 kHz)
Low outside parts
Built-in standby switch function (pin 1)
Built-in muting function (pin 6)
Built-in various protection circuits: Thermal shut down, overvoltage, out to GND, out to V_CC, out to out short speaker burned
Operating supply voltage
: V_{CC (opr)} = 9 to 26 V (R_L = 8 )
: V_{CC (opr)} = 9 to 18 V (R_L = 4 )
Note 1: Install the device correctly. Otherwise, the device or system may be degraded, damaged or even destroyed.
Note 2: The protection features are intended to avoid output short-circuits or other abnormal conditions temporarily. It is not guaranteed that they will prevent the IC from being damaged. Exposure to conditions beyond the guaranteed operating ranges may not activate the protection features, resulting in an IC damage due to output short-circuits.
Note 3: If HBM ESD(condition; 100pF/1.5k) of under -1900V is applied to pin 2 or pin 4 in case that pin3 is GND, this product may break down.

The absolute maximum ratings of a semiconductor device are a set of specified parameter values, which must not be exceeded during operation, even for an instant. If any of these rating would be exceeded during operation, the device electrical characteristics may be irreparably altered and the reliability and lifetime of the device can no longer be guaranteed. Moreover, these operations with exceeded ratings may cause break down, damage and/or degradation to any other equipment. Applications using the device should be designed such that each absolute maximum rating will never be exceeded in any operating conditions. Before using, creating and/or producing designs, refer to and comply with the precautions and conditions set forth in this documents.
