8.2.1.2 Detailed Design Procedure
The transfer function of the circuit in Figure 8-1 is given in Equation 1.

The load current (ILOAD) produces a voltage drop across the shunt resistor (RSHUNT). The load current is set
from 0 A to 1 A. To keep the shunt voltage below 100 mV at maximum load current, the largest shunt resistor is
defined using Equation 2.

Using Equation 2, RSHUNT is calculated to be 100 mΩ. The voltage drop produced by ILOAD and RSHUNT is
amplified by the TLV9151 to produce an output voltage of 0 V to 4.9 V. The gain needed by the TLV9151 to
produce the necessary output voltage is calculated using Equation 3.

Using Equation 3, the required gain is calculated to be 49 V/V, which is set with resistors RF and RG. Equation 4
is used to size the resistors, RF and RG, to set the gain of the TLV9151 to 49 V/V.

Choosing RF as 360 kΩ, RG is calculated to be 7.5 kΩ. RF and RG were chosen as 360 kΩ and 7.5 kΩ because
they are standard value resistors that create a 49:1 ratio. Other resistors that create a 49:1 ratio can also be
used. Figure 8-2 shows the measured transfer function of the circuit shown in Figure 8-1.
