INA240A1QPWRQ1
Texas Instruments · Current Sense Amplifiers · TSSOP-8
INA240A1QPWRQ1 from Texas Instruments, in a TSSOP-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 | NC | unconnected | Reserved pin with no internal connection; ground or leave floating. |
| 2 | IN+ | input | Analog input connected to power side of shunt resistor; accepts differential input -80V to +80V relative to IN-. |
| 3 | IN- | input | Analog input connected to load side of shunt resistor; common-mode input voltage -4V to 80V independent of supply voltage. |
| 4 | GND | power_in | Analog ground reference. |
| 5 | VS | power_in | Power supply input; operating voltage 2.7V to 5.5V; output voltage range limited to GND to VS. |
| 6 | REF2 | input | Reference voltage 2 input; connect to 0V to VS to adjust output midpoint for single or bidirectional current measurement. |
| 7 | REF1 | input | Reference voltage 1 input; connect to 0V to VS to adjust output midpoint for single or bidirectional current measurement. |
| 8 | OUT | output | Analog output voltage proportional to differential input sensed across shunt resistor with 20V/V gain. |
