ADA4571-2WHRZ-RL

Analog Devices · Position Sensor · SOIC-16

ADA4571-2WHRZ-RL from Analog Devices, in a SOIC-16. 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 VTEMP2 output Temperature output for channel 2, ratiometric to supply, 50 Ω buffered output; must be left open when not in use.
2 GND2 power_in Ground for channel 2.
3 VDD2 power_in Channel 2 supply, 3 V to 5.5 V.
4 PD2 input Active-high power-down for channel 2; outputs go high impedance when tied to VDD2, and an internal pull-down keeps the device active if left floating.
5 GC1 input Active-high gain control mode for channel 1; connect to VDD1 to enable, and a weak pull-up enables it by default if left floating.
6 VCOS1 output Analog cosine output of channel 1, ratiometric to VDD with 60 Ω series resistance and a 10 nF load capacitor to GND1.
7 GND1 power_in Ground for channel 1.
8 VSIN1 output Analog sine output of channel 1, ratiometric to VDD with 60 Ω series resistance and a 10 nF load capacitor to GND1.
9 VTEMP1 output Temperature output for channel 1, ratiometric to supply, 50 Ω buffered output; must be left open when not in use.
10 GND1 power_in Ground for channel 1.
11 VDD1 power_in Channel 1 supply, 3 V to 5.5 V.
12 PD1 input Active-high power-down for channel 1; outputs go high impedance when tied to VDD1, and an internal pull-down keeps the device active if left floating.
