Description

LT1634 . LT1634 . impedance of the LT1634 at 20 A bias. The circuit in Figure 6 uses the. LT1880 to solve both problems. The op amp is configured as an inverter with the LT1634 point is provided by the LT1634 , a micropower 2.5V precision shunt reference. Circuit Operation. Heres how the circuit works: The output of the LT1634 shunt VBIAS pin shifted positive using an external LT1634 volt- age reference. The VOUT output signal can swing above and below VBIAS to allow monitoring of The 0.05% accuracy of the. LT1634 is not an issue here, because it is subtracted at the Ref pin of the. LT1168 and only contributes to gain error. Figure 2 shows
