This active low input disables the main ground connections and should be connected both outputs. into a star ground or ground plane. The exposed pad V must be soldered to ground for good electrical contact IN2 (Pin 10): Input Voltage Supply for Buffer 2. Bypass V and rated thermal performance. IN2 with 0.1μF capacitor to ground. This pin supplies power to buffer amplifier 2. BYPASS (Pin 3): Bypass Pin. This requires a 1μF capaci- V tor for bandgap stability. IN1 (Pin 11): Input Voltage Supply for Buffer 1. Bypass VIN1 with 0.1μF capacitor to ground. This pin supplies DNC (Pin 4, 16): Do Not Connect. Keep leakage current power to buffer amplifier 1. from these pins to a minimum. VOUT1_F (Pin 12): VOUT1 Output Voltage. A 1μF to 50μF NR (Pin 5): Noise Reduction Pin. To band limit the noise output capacitor is required for stable operation. This out- of the reference, connect a capacitor between this pin and put can source up to 150mA. ground. See Applications Information section. VOUT1_S (Pin 13): VOUT1 Kelvin Sense Pin. Connect this VOUT2_S (Pin 7): VOUT2 Kelvin Sense Pin. Connect this pin sense pin directly to the load. directly to the load. VIN (Pin 14): Input Voltage Supply. Bypass VIN with 0.1μF VOUT2_F (Pin 8): VOUT2 Output Voltage. A 1μF to 50μF out- capacitor to ground. put capacitor is required for stable operation. This output NC (Pin 15): No Connect. can source up to 50mA. Rev.
