Preliminary Information
Absolute Maximum Ratings
Exceeding these values may cause permanent damage. Functional operation under these conditions is not implied.
Typical figures are at 25
°
C with nominal+ 5V supplies and are for design aid only: not guaranteed and not subject to production testing.
DC Electrical Characteristics
DC Electrical Characteristics are over recommended operating conditions with V
at +5.0V and V
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.
x
Supply Current and Power Consumption characteristics are over recommended operating conditions with V
DD
at 5.0V, V
EE
at -5.0V and V
BAT
at -48V.
Note that
loop current flows through both the V
BAT
and the V
DD
supply.
y
SHK output consists of a 100k
resistor in series with an op-amp with a minimum output voltage swing of ±3.25V.
z
LED outputs consists of a 2.5k
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.
