INA204AIDR from Texas Instruments, in a SOIC-14. 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 | VS | power_in | Power supply input; the recommended operating supply is 2.7 V to 18 V (12 V nominal) and the absolute maximum is 18 V. |
| 2 | OUT | output | Current-shunt monitor analog output voltage, limited to GND - 0.3 V to (VS) + 0.3 V per the absolute maximum ratings. |
| 3 | CMP1 IN-/0.6-V Ref | input | Comparator 1 negative input that can be used to override the internal 0.6-V reference; comparator analog input limits are GND - 0.3 V to (VS) + 0.3 V. |
| 4 | CMP1 IN+ | input | Comparator 1 positive input; comparator analog input limits are GND - 0.3 V to (VS) + 0.3 V. |
| 5 | CMP2 IN+ | input | Comparator 2 positive input; comparator analog input limits are GND - 0.3 V to (VS) + 0.3 V. |
| 6 | CMP2 IN-/0.6V REF | input | Comparator 2 negative input that can be used to override the internal 0.6-V reference; comparator analog input limits are GND - 0.3 V to (VS) + 0.3 V. |
| 7 | GND | power_in | Ground reference for the device. |
| 8 | CMP1 RESET | input | Active-low output reset input for comparator 1 (latched comparator); reset pin limits are GND - 0.3 V to (VS) + 0.3 V. |
| 9 | CMP2 DELAY | input | Connect an optional capacitor to this pin to adjust the comparator 2 delay; the VREF and CMP2 delay pin rating is GND - 0.3 V to 10 V. |
| 10 | CMP2 OUT | output | Comparator 2 open-drain output; the comparator output pin rating is GND - 0.3 V to 18 V. |
| 11 | CMP1 OUT | output | Comparator 1 open-drain output; the comparator output pin rating is GND - 0.3 V to 18 V. |
| 12 | 1.2-V REF OUT | output | 1.2-V internal reference output; the VREF pin rating is GND - 0.3 V to 10 V. |
| 13 | VIN- | power_in | Connect to the low side of the shunt; the common-mode input range is -16 V to 80 V and the differential input range is -18 V to 18 V. |
| 14 | VIN+ | power_in | Connect to the high side of the shunt; the common-mode input range is -16 V to 80 V and the differential input range is -18 V to 18 V. |
