Function Documentation

ad9739a_dac_fs_current()

float ad9739a_dac_fs_current	(	struct ad9739a_dev *	dev,
		float	fs_val
	)

Sets the full-scale output current for the DAC.

Sets the full-scale output current for the DAC.

Parameters

dev	- The device structure.
fs_val	- The desired full-scale output current. Accepted values: 8.7 to 32.7 (mA) and 0. When fs_val is set to 0 the DAC output is disabled(sleep).

Returns

Returns the actual set full-scale current or negative error code.
