1 NC Tie to Ground1 or Pin 16. 2 VCC Positive Power Supply Voltage. 3 ENBL Logic 1 enables the part, and Logic 0 disables the part. 4 VOUT Open End of Internal 10 kΩ Resistor. Tie one end of external antialiasing filter capacitor (6.8 nF) to this pin, and tie the other end to ground.1 5 CF2 Tie one end of the CFILTER (68 nF) that is in parallel with the internal gain resistor to this pin. 6 CF1 Tie the other end of the CFILTER (68 nF) that is in parallel with the internal gain resistor to this pin. 7 NC Tie to Ground.1 8 NC Tie to Ground.1 9 NC Tie to Ground.1 10 GND Ground1 or Negative Power Supply Voltage. 11 RSET Tie one end of Resistor RSET to this pin to set the excitation current and tie the other end of Resistor RSET to Pin 10. 12 NC Tie to Ground.1 13 IOUT Excitation Current Output. Tie one end of CBRIDGE (0.1 μF) to this pin and tie the other end of CBRIDGE to ground.1 14 VINN Negative Input Terminal. 15 VINP Positive Input Terminal. 16 NC Tie to Ground1 or Pin 1. 17/Pad NC Pad should be floating and not tied to any potential. 1 During dual-supply operation, ground becomes the negative power supply voltage.
