Specifications
Comparator Level OUT Pin Voltage at Ta = 25°C, V
Ordering number: EN683D
AC level meters such as VU meters.
DC level meters such as signal meters.
Display
Nine red or green LEDs display the input level in the shape
of a bar.
Input amplifier
Wide application is available owing to built-in DC amplifier
whose gain is variable with external resistors.
Comparator level
Setting is made by steps of 3 dB as follows.
–18 dB, –15 dB, –12 dB, –9 dB, –6 dB, –3 dB, 0 dB,
+3 dB, +6 dB
Supply voltage
The recommended supply voltage range is so wide as 5.5 V
to 16 V.
(If pin Vref 2 is used, 7 V to 16 V.)
Reference voltage
Constant voltage output is available with external transistor
owing to pin Vref 2 = 5 V.
Comparator level
SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other
parameters) listed in products specifications of any and all SANYO products described or contained
herein.
Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.
