INTRODUCTION
The S1A2284A01 and S1A2284A02 are monolithic integrated circuits designed for 5-dot LED level meter drivers with a built-in rectifying amplifier. It is suitable for AC/DC level meters such as VU meters or signal meters.

FEATURES
• High gain rectifying amplifier included (GV = 26dB)
• Low radiation noise when LED turns on
• Logarithmic indicator for 5-dot bar type LED (-10, -5, 0, 3, 6dB)
• Constant current output
   S1A2284A01: lo = 15mA (Typ)
   S1A2284A02: Io = 7mA (Typ)
• Wide operating supply voltage range:
   VCC = 3.5V - 1 6V
• Minimum number of external parts required
