AD820ARZ-REEL7

Analog Devices · FET Input Amplifiers · SOIC-8

AD820ARZ-REEL7 from Analog Devices, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No internal connection; offset null adjust pins are not functional in the SOIC (R) package.
2 -IN input Inverting input; FET input stage with differential input impedance 10¹³ Ω ‖ 0.5 pF, max input bias current 25 pA, max input offset current 20 pA.
3 +IN input Non-inverting input; common-mode range extends 0.2 V below -VS to 1 V below +VS; common-mode input impedance 10¹³ Ω ‖ 2.8 pF.
4 -VS power_in Negative supply rail; 0 V for single-supply operation (+3 V to +36 V total) or -1.5 V to -18 V for dual-supply; absolute maximum supply voltage ±18 V.
5 NC unconnected No internal connection.
6 VOUT output Rail-to-rail output; swings within 5 mV of -VS and 10 mV of +VS at 20 µA load; minimum output current 15 mA; drives up to 350 pF capacitive load.
7 +VS power_in Positive supply rail; +3 V to +36 V single supply or +1.5 V to +18 V dual supply; quiescent current 800 µA max; absolute maximum supply voltage ±18 V.
8 NC unconnected No internal connection; offset null adjust pins are not functional in the SOIC (R) package.
