TS4962 ST Microelectronics, Inc., TS4962 Datasheet - Page 7

• Manufacturer Part Number: TS4962
• Manufacturer: ST Microelectronics, Inc.

Electrical Characteristics
1) All electrical values are guaranted with correlation measurements at 2.5V and 5V.
2) Standby mode is actived when Vstdby is tied to GND.
3) Dynamic measurements - 20*log(rms(Vout)/rms(Vripple)). Vripple is the surimposed sinus signal to Vcc @ f = 217Hz.
