PIN FUNCTIONS GND (Pins 1, 2, 6, Exposed Pad Pin 17):
These pins are
OD (Pin 9):
Output Disable. 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
