Description
This pin sets bias current in the TC9400. Connect to V
SS
through a 100 k
resistor.
See text.
Low frequency adjustment input. See text.
Input current connection for the V/F converter.
Negative power supply voltage connection, typically – 5V.
Reference capacitor connection.
Analog ground.
Voltage reference input, typically – 5V.
Frequency output. This open drain output will pulse LOW each time the Freq
threshold detector limit is reached. The pulse rate is proportional to input voltage.
Source connection for the open drain output FETs. See text.
This open drain output is a square wave at one half the frequency of the pulse
output (pin 8). Output transitions of this pin occur on the rising edge of pin 8.
Input to the threshold detector. This pin is the frequency input during F/V operation.
Output of the integrator amplifier.
No internal connection
Positive power supply connection, typically +5V.
