Install a standard 9-V alkaline
rectangular battery to J1 or a bench DC power supply that can
be connected with hook test clips to Vbatt/Vin (TP1) and GND
(TP3). The supply voltage range for the board is 6-V to 12-V DC. When using
a 9-V power supply, the input current is 33 mA to 46 mA at slow and fast slew
rates, respectively.
Turn on Power (S1), verify
the Pgood (D7) LED turns on
Probe Pulse (TP10), and
trigger the signal on an oscilloscope
Probe INP (TP7), and
monitor the signal
Adjust Low (R15) and
High (R23) to the desired low and high levels, respectively
Adjust Settling Time(R43) for the cleanest INP signal. This can require additional tuning
after connecting the device.
