UVP1, UVP2, UVP3 V Para. Unbalance Control

UVPS is defined as the voltage of parabola start point. UVPE is defined as the voltage of parabola end point. UVP1, UVP2,

UVP3 is defined as follows

UVP1, UVP2, UVP3 = UVPS − UVPE

Measure the unbalance of parabola waveform at pin 4 when the voltage of pin 3 is 2.8 V, 3.5 V, and 4.2 V. Pin 5 is

controlled so that the amplitude of parabola is 3 VP-P constant.

VUVP1 V Unbalance VCC. Characteristics1

When the supply voltage of pin 10, 20 is 11.5 V, the unbalance of parabola waveform at pin 4 is defined as UVP11.5 V.

VUHP1 = UVP2 − UVP11.5 V

VUVP2 V Unbalance VCC. Characteristics2

When the supply voltage of pin 10, 20 is 12.5 V, the unbalance of parabola waveform at pin 4 is defined as UVP 12.5 V.

VUVP2 = UVP2 − UVP12.5 V

DUVP V Unbalance Temperature Drift

Measure temperature drift of UVP2 (−20°C to 85°C)

GVP1, GVP2, GVP3 V Parabola Amplitude

Measure the amplitude of parabola waveform at pin 4 when the voltage of pin 5 is 1 V, 2 V, and 3 V.

FVP1 V Para. Freq. Characteristics1

When the frequency of input signal in pin 2 is 70 Hz, the amplitude of parabola waveform at pin 4 is defined as VP70 Hz.

When the frequency of input signal is 50 Hz, the amplitude of parabola waveform is defined as VP50 Hz.

FVP1 = VP70 Hz − VP50 Hz

FVP2 V Para. Freq. Characteristics2

When the frequency of input signal in pin 2 is 185 Hz, the amplitude of parabola waveform at pin 4 is defined as VP185

Hz.

FVP2 = VP70 Hz − VP185 Hz

VVP1 V Para. VCC. Characteristics1

When the voltage of pin 10, 20 is 12.0 V, the amplitude of parabola waveform is defined as VP12.0 V. When the voltage

is 11.5 V, the amplitude of parabola waveform is defined as VP11.5 V.

VVP1 = VP12.0 V − VP11.5 V

VVP2 V Para. VCC. Characteristics2

When the voltage of pin 10, 20 is 12.5 V, the amplitude of parabola waveform is defined as VP12.5 V.

VVP2 = VP12.0 V − VP12.5 V
