Detailed Description

Class specific to the AD5686R DAC.

Used for the HV DAC on the LoLX SiPM board.

Member Function Documentation

◆ EnableHV()

bool AD5686R::EnableHV ( bool on = true )

Turn HV amplifier on/off.

DAC channel 3 is used as a digital switch to turn the HV supply on/off. This is done to ensure the HV is off when the board is powered up. We can not guarantee the nanoPi itself doesn't set arbitrary pins to HIGH during the boot process.

◆ GetSetting()

uint16_t AD5686R::GetSetting	(	double	v,
		unsigned short	chan )

virtual

Calibration specific to the HV DAC.

Implements AD56x6.

◆ GetVoltage()

double AD5686R::GetVoltage	(	uint16_t	s,
		unsigned short	chan )

virtual

Calibration specific to the HV DAC.

Implements AD56x6.

◆ SetCalib()

void AD5686R::SetCalib	(	std::vector< double >	sl,
		std::vector< double >	offs )

inline

Parameters

offs	Method to change the calibration constants
