ADA4870ACPZ

Analog Devices · Operational Amplifier · LFCSP-48(7x7)

ADA4870ACPZ from Analog Devices, in a LFCSP-48(7x7). 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 SD input Shutdown input, active low and referenced to VEE; pull SD high or low and do not leave it floating, since pulling it low reduces quiescent current to approximately 750 µA.
2 NC unconnected No connect; do not electrically connect to this pin, solder down to the PCB pads only for mechanical integrity.
3 ON input Turn on/enable input, active low and referenced to VEE; pull low after initial power-up, and floating it enables short-circuit protection with an impedance of about 20 kΩ.
4 NC unconnected No connect; do not electrically connect to this pin, solder down to the PCB pads only for mechanical integrity.
5 NC unconnected No connect; do not electrically connect to this pin, solder down to the PCB pads only for mechanical integrity.
