See text.

Zero Adj

I_IN

Low frequency adjustment input. See text.

Input current connection for the V/F converter.

Negative power supply voltage connection, typically – 5V.

Reference capacitor connection.

V_SS

V_REFOUT

GND

Analog ground.

V_REF

Voltage reference input, typically – 5V.

Pulse Freq Out

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.

Output Common

Freq/2 Out

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.

Threshold Detect

Amplifier Out

Inputtothethresholddetector. ThispinisthefrequencyinputduringF/Voperation.

Output of the integrator amplifier.

No internal connection

V_DD

Positive power supply connection, typically +5V.
