**Analog Devices** · Pre-ordered Chips · MSOP-8

AD8495CRMZ 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 input of the thermocouple amplifier; inputs withstand up to 25 V beyond the opposite supply rail (OVP) and 4 kV ESD, and a 1 MΩ resistor to ground enables open-thermocouple detection. |
| 2 | REF | input | Reference pin that offsets the output voltage (VOUT = TMJ × 5 mV/°C + VREF); it must be driven by a low impedance source and should not go beyond 0.3 V of the supply rails. |
| 3 | −VS | power_in | Negative supply (ground on single supply); dual supply operation is ±2.7 V to ±18 V. |
| 4 | NC | unconnected | No connect pin. |
| 5 | SENSE | input | Sense pin that connects to the output in measurement mode or to the setpoint voltage in setpoint mode, and should not go beyond 0.3 V of the supply rails. |
| 6 | OUT | output | Output at 5 mV/°C, with a range of -VS + 0.025 V to +VS - 0.1 V and 7 mA typical short-circuit current. |
| 7 | +VS | power_in | Positive supply, with single-supply operation from 2.7 V to 36 V and a maximum rating of ±18 V on the supply voltage. |
| 8 | +IN | input | Positive input of the thermocouple amplifier; inputs withstand up to 25 V beyond the opposite supply rail (OVP) and 4 kV ESD. |
