14-Pin PDIP/CERDIP

14-Pin SOIC (Narrow)

Symbol

Description

I_BIAS

ZERO ADJ

I_IN

This pin sets bias current in the TC9400. Connect to V_SSthrough a 100kΩ resistor.

Low frequency adjustment input.

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

Source connection for the open drain output FETs.

COMMON

FREQ/2 OUT

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

DETECTOR

Input to the Threshold Detector. This pin is the frequency input during F/V operation.

AMPLIFIER OUT Output of the integrator amplifier.

No internal connection.

V_DD

Positive power supply connection, typically +5V.
