UHP1, UHP2, UHP3 H para. Unbalance Control

UHPS is defined as the voltage of parabola start point. UHPE is defined as the voltage of parabola end point. UHP1, UHP2,

UHP3 is defined as follows

UHP1, UHP2, UHP3 = UHPS − UHPE

Measure the unbalance of parabola waveform at pin 4 when the voltage of pin 19 is 5.7 V, 6.1 V, and 6.4 V. Pin 6 is

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

Output signal at pin 7

UHP UHPE

VUHP1 H para. Unbalance VCC. Characteristics1

When the supply voltage of pin 10, 20 is 11.5 V, the unbalance of parabola waveform at pin 7 is defined as UHP11.5 V.

VUHP1 = UHP2 − UHP11.5 V

VUHP2 H para. Unbalance VCC. Characteristics2

When the supply voltage of pin 10, 20 is 12.5 V, the unbalance of parabola waveform at pin 7 is defined as UHP12.5 V.

VUHP2 = UHP2 − UHP12.5 V

DUHP H para. Unbalance Temperature Drift

Measure temperature drift of UHP2. (−20°C to 85°C)

GHP1 H Para. Gain Control1

Measure the amplitude of parabola waveform at pin 7 and it is defined as HP−6, 1.0 V.

GHP2 H Para. Gain Control2

The amplitude of parabola waveform at pin 7 is defined as HP−6, 2.5 V.

GHP3 H Para. Gain Control3

The amplitude of parabola waveform at pin 7 is defined as HP−6, 4.0 V.

FHP1 H Para. Freq. Characteristics1

When the frequency of input signal in pin 17 is 96 kHz, the amplitude of parabola waveform at pin 7 is defined as HP96

kHz. When the frequency of input signal is 24 kHz, the amplitude of parabola waveform is defined as HP24 kHz.

FHP1 = HP96 kHz − HP24 kHz

FHP2 H Para. Freq. Characteristics2

When the frequency of input signal in pin 17 is 140 kHz, the amplitude of parabola waveform at pin 7 is defined as

HP120 kHz.

FHP2 = HP96 kHz − HP140 kHz
