LM94022QBIMGX from Texas Instruments, in a SC-70-5. 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 | GS0 | input | Gain Select 0 is one of two logic inputs that select the output slope (GS1 and GS0 together select −5.5, −8.2, −10.9 or −13.6 mV/°C per Table 1), and it can be tied directly to VDD or GND without pullup or pulldown resistors; absolute maximum voltage on GS0 is −0.3 V to 6 V. |
| 2 | GND | power_in | Ground is the power supply ground pin for the device. |
| 3 | OUT | output | Analog output that provides a voltage inversely proportional to temperature; output pin voltage is limited to −0.3 V to (VDD + 0.5) V and output current to ±7 mA (absolute maximum ratings). |
| 4 | VDD | power_in | Positive supply voltage, recommended operating range 1.5 V to 5.5 V (absolute maximum 6 V). |
| 5 | GS1 | input | Gain Select 1 is one of two logic inputs that select the output slope together with GS0 (Table 1), and it can be tied directly to VDD or GND without pullup or pulldown resistors; absolute maximum voltage on GS1 is −0.3 V to 6 V. |
