ELECTRICAL CHARACTERISTICS Note 4:
Both the LT1996C and LT1996I are guaranteed functional over the determine the valid input voltage range under various operating –40°C to 85°C temperature range. conditions.
Note 5:
The LT1996C is guaranteed to meet the specified performance
Note 8:
Offset voltage, offset voltage drift and PSRR are defined as from 0°C to 70°C and is designed, characterized and expected to meet referred to the internal op amp. You can calculate output offset as follows. specified performance from –40°C to 85°C but is not tested or QA In the case of balanced source resistance, VOS, OUT = VOS • Noise Gain + sampled at these temperatures. The LT1996I is guaranteed to meet IOS • 450k + IB • 450k • (1 – RP/RN) where RP and RN are the total specified performance from –40°C to 85°C. resistance at the op amp positive and negative terminal respectively.
Note 6:
This parameter is not 100% tested.
Note 9:
Resistors connected to the minus inputs. Resistor matching is not
Note 7:
Input voltage range is guaranteed by the CMRR test at V tested directly, but is guaranteed by the gain error test. S = ±15V. For the other voltages, this parameter is guaranteed by design and through
Note 10:
Input impedance is tested by a combination of direct correlation with the ±15V test. See the Applications Information section to measurements and correlation to the CMRR and gain error tests.
