DEFINITION
SYMBOL
Auxiliary Amplifier Out.
Auxiliary Amplifier non-inverting input.
Auxiliary Amplifier inverting input.
Input to Synchronous Demodulator from the LVDT/RVDT secondary.
Pulsating DC output from the Synchronous Demodulator output. This voltage should be filtered before
use.
Synchronizing input for the Synchronizing Demodulator. This input should be connected to the OSC or
OSC output. Sync is referenced to V
REF
/2.
Device return. Should be connected to system ground or to the negative supply.
No internal connection.
No internal connection.
No internal connection.
A temperature stable 18k
resistor should be connected between this pin and Pin 7.
A high impedance source of one half the potential applied to V
. The LVDT/RVDT secondary return
should be to this point. A bypass capacitor with low impedance at the oscillator frequency should also be
connected between this pin and ground.
Oscillator sine wave output that is 180
°
out of phase with the OSC signal. The LVDT/RVDT primary is
usually connected between OSC and OSC pins.
Oscillator sine wave output. The LVDT/RVDT primaries are usually connected between OSC and OSC
pins.
Usually connected to the OSC output for unity gain, a resistor between this pin and OSC, and one be-
tween this pin and ground can provide for a change in the oscillator output pin amplitudes.
Reference voltage input for the oscillator and sine converter. This voltage MUST be stable and must not
exceed +V supply voltage.
Oscillator frequency-determining capacitor. The capacitor connected between this pin and ground should
be a temperature-stable type.
Positive supply connection.
