Setting the Gain
The gain of the LT1789-1 and LT1789-10 is set by the
value of resistor RG, applied across pins 1 and 8. For the
LT1789-1, the gain G will be:
G = 1+ 200k/RG
and RG can be calculated from the desired gain by
RG = 200k/(G – 1)
For the LT1789-10, the gain G will be
G =10 (1 + 200k/RG)
and RG can be calculated from the desired gain by
RG = 200k/(0.1 G – 1)
For the lowest achievable gain, RG may be set to infinity
by leaving Pins 1 and 8 open.
Input and Output Offset Voltage
The offset voltage of the LT1789-1/LT1789-10 has two
components: the output offset and the input offset. The
total offset voltage referred to the input (RTI) is found by
dividing the output offset by the programmed gain (G) and
adding it to the input offset. At high gains the input offset
voltage dominates, whereas at low gains the output offset
voltage dominates. The total offset voltage is:
