This register selects the positive side from each channel for lead-off detection. See the Lead-Off Detection

subsection of the ECG-Specific Functions section for details. Note that the LOFF_STATP register bits are only

valid if the corresponding LOFF_SENSP bits are set to '1'.

Note that registers bits[5:4] are not available for the ADS1194. Bits[7:6] are not available for the ADS1194 and

ADS1196.

LOFF1N

This register selects the negative side from each channel for lead-off detection. See the Lead-Off Detection

subsection of the ECG-Specific Functions section for details. Note that the LOFF_STATN register bits are only

valid if the corresponding LOFF_SENSN bits are set to '1'.

Note that registers bits[5:4] are not available for the ADS1194. Bits[7:6] are not available for the ADS1194 and

ADS1196.

This register controls the direction of the current used for lead-off derivation. See the Lead-Off Detection

subsection of the ECG-Specific Functions section for details.

IN8P_OFF

IN7P_OFF

IN6P_OFF

IN5P_OFF

IN4P_OFF

IN3P_OFF

IN2P_OFF

IN1P_OFF

This register stores the status of whether the positive electrode on each channel is on or off. See the Lead-Off

Detection subsection of the ECG-Specific Functions section for details.

'0' is lead-on (default) and '1' is lead-off. Ignore the LOFF_STATP values if the corresponding LOFF_SENSP bits

are not set to '1'. When the LOFF_SENSEP bits are '0', the LOFF_STATP bits should be ignored.

LOFF_STATN (Read-Only Register)

Address = 13h

BIT 7

BIT 6

BIT 5

BIT 4

BIT 0

IN8N_OFF

IN7N_OFF

IN6N_OFF

IN5N_OFF

IN4N_OFF

IN3N_OFF

IN2N_OFF

IN1N_OFF

This register stores the status of whether the negative electrode on each channel is on or off. See the Lead-Off

Detection subsection of the ECG-Specific Functions section for details. Ignore the LOFF_STATN values if the

corresponding LOFF_SENSN bits are not set to '1'.

'0' is lead-on (default) and '1' is lead-off. When the LOFF_SENSEN bits are '0', the LOFF_STATP bits should be

ignored.
