ACNT-H87A-500E

AVAGO(Broadcom) · Isolation Amplifiers · SO-8

ACNT-H87A-500E from AVAGO(Broadcom), in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD1 power_in Supply voltage for input side (4.5V to 5.5V), relative to GND1; requires a 0.1-µF bypass capacitor between pins 1 and 4.
2 VIN power_in Voltage input with 0 to 2V nominal range (2.46V full scale) referenced to GND1 and 1-GΩ input impedance.
3 SHDN input Active-high shutdown pin that reduces IDD1 to 15 µA typical when driven to VDD1.
4 GND1 power_in Input side ground.
5 GND2 power_in Output side ground.
6 VOUT- output Negative output of the differential output pair, with 1.23V common-mode voltage and 30 mA typical short-circuit current.
7 VOUT+ output Positive output of the differential output pair, with 1.23V common-mode voltage and 30 mA typical short-circuit current.
8 VDD2 power_in Supply voltage for output side (3V to 5.5V), referenced to GND2; requires a 0.1-µF bypass capacitor between pins 5 and 8.
