This pin sets bias current in the TC9400. Connect to V
Low frequency adjustment input.
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.
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.
No internal connection.
Positive power supply connection, typically +5V.
