NOTES
1_{Input Offset Voltage measurements are performed by automated equipment approximately 0.5 seconds after application of power.}
2_{The TCVOS performance is within the specifications unnulled or when nulled with R P = 8 kW to 20 kW, optimum performance is obtained with RP = 8 kW.}
3_{Sample tested.}
Specifications subject to change without notice.
