PIN FUNCTIONS V – S (Pin 1):
Negative Sense Input Terminal. Negative
A2 (Pin 6):
Gain Select Pin. Refer to Table 1. sense voltage input will remain functional for voltages
A4 (Pin 7):
Gain Select Pin. When Pin 7 is shorted to V up to 48V. V – EE, S is connected to an internal gain-setting the total gain is 40V/V. When both Pin 6 and Pin 7 are resistor RG1 = 5k. shorted to VEE, the total gain is 50V/V. When both Pin 6
VCC (Pin 2):
Supply Voltage Input. This power supply pin and Pin 7 are opened, the total gain is 10V/V. supplies current to both current sense amplifier and op amp.
V + S (Pin 8):
Positive Sense Input Terminal. Connecting a
FIL (Pin 3):
Filter Pin. Connects to an external capacitor supply to V + – S and a load to VS will allow the LT6100 to to roll off differential noise of the system. Pole frequency monitor the current through R + SENSE, refer to Figure 1. VS f–3dB = 1/(2πRFILC), RFIL = RE + RO = 60k. is connected to an internal gain setting resistor RG2 = 5k. +
V
VS remains functional for voltages up to 48V.
EE (Pin 4):
Negative Supply or Ground for Single Supply Operation.
VOUT (Pin 5):
Voltage Output Proportional to the Magnitude of the Current Flowing Through RSENSE: VOUT = AV • (VSENSE ± VOS) VOS is the input offset voltage. AV is the total gain of the LT6100. 6100fd For more information www.linear.com/LT6100 9
