Programmable Gain Amplifier (PGA)
3 below describes the options for E1 and E2.
The CS5462 is equipped with a PGA on the current
FREQ
channel. While the voltage channel is always set to
a 10x differential input voltage range (500 mV P-P ),
the current channel can be set to one of two differ-
ent input ranges. The maximum differential voltage
range on the current channel can be set to 10x
(500 mV P-P ) and 50x (100 mV P-P ).
The gain setting of the current channel’s PGA and
also the high pass filter option are selected by con-

must be tied to one and only one Program Select

For all applications FREQ must be connected to

rate and pulse width will decrease by a percentage
equal to the product of the percentages of full-
scale inputs across each channel. For example, if

During Startup the CS5462 will scan the IGAIN in-
put pin and determine which Program Select out-
put it is connected to and then set the PGA and
HPF’s accordingly.
In stepper motor mode the CS5462 produces alter-
nating pulses on E1 and E2. This pulse format is
designed to directly drive a stepper motor. Each
pin produces active-low pulses with frequency de-
pendent pulse widths. The figure below shows the

option.
E1 and E2 pins provide a simple interface from
which signed energy can be accumulated. E1 and
