Negative battery supply (for IDT82V1671: −52 V ≤ VBH ≤ −20 V; for IDT82V1671A: −70 V ≤ VBH ≤ −52 V)
Ring sense, connected to the RING pin through an external resistor R
for details.
Battery ground. This pin should be externally connected to AGND.
Tip sense, connected to the TIP pin through an external resistor R
+3.3 V power supply.
Analog ground. This pin should be externally connected to BGND.
Output voltage of VBAT/2 (VBAT represents the selected battery voltage VBH or VBL). An external capacitor is
connected between this pin and the ground for filtering.
Reference voltage input, typical 1.5 V.
Differential AC voltage, negative.

Sense transversal AC voltage.
External capacitor connection. An external capacitor is connected between this pin and the CB pin to separate the DC
component from the sense transversal voltage.
Sense transversal DC voltage.
Sense longitudinal voltage.
External capacitor connection. An external capacitor is connected between this pin and the CA pin to separate the DC
component from the sense transversal voltage.
Mode control input 3 or temperature information output.
The logic level of the CS pin determines the direction of the M3 pin. See the description of the CS pin for details.
Mode control input 2. This is a binary logic pin, together with M1 and M3, controlling the operating mode of the RSLIC.
Mode control input 1. This is a binary logic pin, together with M2 and M3, controlling the operating mode of the RSLIC.
Chip select input. It is a ternary logic pin.
