TS4890 ST Microelectronics, Inc., TS4890 Datasheet - Page 3

• Manufacturer Part Number: TS4890
• Description: 1W Mono Audio Amplifier With Standby Active High
• Manufacturer: ST Microelectronics, Inc.

ELECTRICAL CHARACTERISTICS
V
1. Standby mode is actived when Vstdby is tied to GND
2. Dynamic measurements - 20*log(rms(Vout)/rms(Vripple)). Vripple is the surimposed sinus signal to Vcc @ f = 217Hz
