AD8495CRMZ-R7 from Analog Devices, in a MSOP-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 | -IN | input | Negative thermocouple input; the input stage uses PNP transistors so bias current always flows out of the pin, and a 1 MΩ resistor to ground enables open-thermocouple detection. |
| 2 | REF | input | Reference pin must be driven by a low-impedance source (not a resistor divider), and its voltage must not go beyond 0.3 V of the supply rails. |
| 3 | -VS | power_in | Negative supply; operating range is 2.7 V to 36 V single supply or ±2.7 V to ±18 V dual supply. |
| 4 | NC | unconnected | No connect; this pin is not internally connected. |
| 5 | SENSE | input | Sense pin, connected to the output in measurement mode or to the setpoint voltage in setpoint mode, and its voltage must not go beyond 0.3 V of the supply rails. |
| 6 | OUT | output | Output with a range of −VS + 0.025 V to +VS − 0.1 V and a typical short-circuit current of 7 mA. |
| 7 | +VS | power_in | Positive supply; operating range is 2.7 V to 36 V single supply or ±2.7 V to ±18 V dual supply. |
| 8 | +IN | input | Positive thermocouple input with an input voltage range of −VS − 0.2 V to +VS − 1.6 V and overvoltage range of +VS − 25 V to −VS + 25 V. |
