5 DOT LED LEVEL METER DRIVER
S1A2284A01/02
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.
9−SIP
FEATURES
• High gain rectifying amplifier included (G_V = 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:
V_CC = 3.5V − 1 6V
• Minimum number of external parts required
