ISINE = 500µA

ISINE = 500µA, EA– = VREF –20mV

ISINE = 500µA, EA– = VREF + 20mV

ISINE = 1mA, EA– = VREF – 20mV

ISINE = 500µA, EA– = VREF – 20mV,

Internal Shunt Zener Voltage

Start-Up, VCC = 14V, TJ = 25°C

Operating, TJ = 25°C

ICC = 30mA

Note 1: Limits are guaranteed by 100% testing, sampling, or correlation with worst-case test conditions.

Note 2: VCC is raised above the Startup Threshold first to activate the IC, then returned to 15V.
