† DC Electrical Characteristics are over recommended operating conditions with VDD at +5.0V and VEE 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 VDD at 5.0V, VEE at -5.0V and VBAT at -48V. Note that
loop current flows through both the VBAT and the VDD supply.
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.
