FGin
FG amplifier/hysteresis comparator
+
• The FG amplifier supports pattern FG and incorporates an internal reference voltage of 2.5 V.
• The FG amplifier is followed by a hysteresis comparator, which compares the FG output and delivers it to
• The FGO output dynamic range is as follows:
• The FGS has an open-collector output. Connect a pull-up resistor considering the following characteristics.
Entering a sine wave of 50 mVpp or greater results in a signal multiplied by the gain being output.
The open loop gain is 45 dB (min) (design target value).
the FGS.
The comparator has a single-side hysteresis of 200 mV for the 2.5 V reference voltage. The square wave
signal output from the FGS enters the internal counter.
The input current is 1 mA (max).
