6.1.1 Input Bias Current

Input bias current (IB) for the TLV4H290-SEP is specified as 5pA typical at TA = 25°C. The input bias current was measured at VS = 5V.

The noninverting input of channel 1 for one sample (unit 787) was found to measure –33.95nA, after exposure to 30krad(Si) under HDR.

After annealing under biased conditions (t = 3 days), this value recovered to <1nA, within the typical distribution of the spec prior to radiation.
