INA154UA from Texas Instruments, in a SOIC-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 | Ref | input | Reference terminal to which the output is referred (normally grounded); a voltage applied here is summed with the output, and its source impedance should be less than 10Ω to maintain good common-mode rejection. |
| 2 | -In | input | Inverting differential input; source impedances on pins 2 and 3 must be nearly equal for good common-mode rejection, and pins 2 and 5 must not be interchanged. |
| 3 | +In | input | Non-inverting differential input; source impedances on pins 2 and 3 must be nearly equal for good common-mode rejection, and pins 1 and 3 must not be interchanged. |
| 4 | V- | power_in | Negative power supply; the device operates from ±4V to ±18V supplies, with V+ to V- absolute maximum of 40V. |
| 5 | Sense | input | Internal resistor-network connection of the difference amplifier; the datasheet gives no further electrical limits for this pin beyond that it must not be interchanged with pin 2. |
| 6 | Output | output | Amplifier output, rated for ±60mA continuous current limit to common and stable with up to 500pF capacitive load. |
| 7 | V+ | power_in | Positive power supply; the device operates from ±4V to ±18V supplies, with V+ to V- absolute maximum of 40V. |
| 8 | NIC | unconnected | No internal connection (NC) on the package; leave unconnected. |
