perature coefficient corrects for the negative temperature co-

efficient of the LM1295. The resistor should be located near

the LM1295. The recommended value is 10 k

Ω.

Rvert (Pin 22): Vertical Resistor. The other end of the Verti-

cal Resistor connects to this pin.

− V Drive (Pin 23): − Vertical Drive. This is the

negative-going vertical ramp output current of the differential

pair. The ramp current waveform is superimposed on a direct

current of approximately 315 µA. The waveform amplitude is

determined by the Vertical Height (pin 2) control voltage and

the Vertical Dynamic Height (pin 6) control voltage. The cur-

rent can be converted into voltage by a resistor (typically 10

k

Ω) to ground or by a differential amplifier using the differen-

tial currents as inputs. The voltage compliance of the output

is typically 6V.

+ V Drive (Pin 24): + Vertical Drive. This is the same as − V

Drive except it is the positive-going output current of the dif-

ferential pair.
