AD620ANZ

Analog Devices · Instrumentation Amplifiers · DIP-8

AD620ANZ from Analog Devices, in a DIP-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	RG	passive	One of two gain-set pins; the gain is G = 1 + 49.4 kΩ/RG, RG should have a TC below 10 ppm/°C, and the pins are left unconnected for G = 1.
2	-IN	input	Inverting input with 400 Ω series thin-film resistance that withstands overloads of up to ±15 V or ±60 mA for several hours, and must stay within the input voltage range (−VS + 1.9 V to +VS − 1.4 V for ±5 V to ±18 V supplies).
3	+IN	input	Non-inverting input with 400 Ω series thin-film resistance that withstands overloads of up to ±15 V or ±60 mA for several hours, and must stay within the input voltage range (−VS + 1.9 V to +VS − 1.4 V for ±5 V to ±18 V supplies).
4	-VS	power_in	Negative supply pin; the operating supply range is ±2.3 V to ±18 V.
5	REF	input	Reference terminal that defines the zero-output voltage, with an allowable range of ±2 V within the supply voltages, and should be tied to a low-impedance point for good CMR.
6	OUTPUT	output	Single-ended output referred to the REF pin potential, with a swing of about −VS + 1.2 V to +VS − 1.4 V at RL = 10 kΩ for ±5 V to ±18 V supplies and a short-circuit current of ±18 mA.
7	+VS	power_in	Positive supply pin; the operating supply range is ±2.3 V to ±18 V.
8	RG	passive	Second gain-set pin; the gain resistor is connected between pins 1 and 8, and the device has a 1.3 mA max quiescent current.
