DESCRIPTION
The demo board for the TS1102 is a completely
assembled and tested circuit board that can be used
for evaluating the current-sense amplifier for all (4)
gain options; i.e., 25V/V, 50V/V, 100V/V, and 200V/V.
The board is configured with an R
SENSE
=R1=50mΩ
resistor. The board has a dedicated RS+=VBATT,
RS-=LOAD, and output voltage OUT=VOUT test
points. For additional information, refer to the TS1102
product data sheet.
All TS1102s are available in a PCB-space saving
5-lead SOT23 surface-mount package.
