† DC Electrical Characteristics are over recommended operating conditions with V
DD
at +5.0V and V
EE
at -5V ± 5% unless otherwise stated.
‡ Typical figures are at 25°C with nominal+ 5V supplies and are for design aid only: not guaranteed and not subject to production testing.

at 5.0V, V
EE
at -5.0V and V
BAT
at -48V.
Note that
loop current flows through both the V

y
SHK output consists of a 100kΩ resistor in series with an op-amp with a minimum output voltage swing of ±3.25V.
z
LED outputs consists of a 2.5kΩ resistor in series with SHK op-amp output.
RRC input consists of a 5kW resistor in series with the base lead of the relay driver transistor (grounded emitter).
{
The MUTE input is internally pulled up. With no input connection, the voltage level at the MUTE input is typically at 1.5V.
