B.1 Power Supplies
Power is supplied to the BL4S100 boards via the Micro-Fit
BL4S100 is protected against reverse polarity by a diode at D27 as shown in Figure B-1.
The input voltage range is from 9 V to 36 V. A switching power regulator is used to provide
+5 V for the BL4S100 logic circuits. In turn, the regulated +5 V DC power supply is used
to drive regulated +1.8 V and +3.3 V power supplies.
The digital ground and the analog ground share a single split ground plane on the board,
with the analog ground connected at a single point to the digital ground by a 0 resistor
(R63). This is done to minimize digital noise in the analog circuits and to eliminate the
possibility of ground loops. External connections to analog ground are made on a screw-
terminal header at J15.
