2.1. Performance Comparison Set-Up

The TS1100 and the MAX9634 evaluation boards were used to perform side-by-side load current measurements.

With on-board 50 m

 sense resistors and a 100 mA load currents, a gain of 50 current sense amplifier and 5mV

sense resistor voltage should ideally generate a 250 mV output voltage. Figures 1 and 2 show the TS1100-50

evaluation board and evaluation board circuit schematic while Figures 3 and 4 show the MAX9634 evaluation

board and evaluation board and circuit schematic, respectively. Figure 5 shows the lab bench setup used to

perform the measurements. Both set-ups were independent and separate instruments were used to perform the

measurements on each evaluation board. In addition, a separate active load was used for each evaluation board.

The only common piece of equipment used was the power supply.
