Note 2: Measured by superimposing 0.75mA ac rms on 7.5 mA dc @ 25°C. Note 3: The maximum allowable change observed over the entire temperature range will not exceed the specified mV change at any discrete temperature between the established limits. Note 4: Voltage measurements to be performed 15 seconds after application of dc current. sales@digitroncorp.com fax +1.908.245-0555 www.digitroncorp.com Rev. 20121112 |
