INA500AIDCKR from Texas Instruments, in a SC-70-6. 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 | Non-inverting (positive) input of the difference amplifier, with the common-mode input range set by the gain and REF voltage (for INA500A with VREF = VS/2, 2*(V-) - VREF to 2*(V+) - VREF). |
| 2 | V- | power_in | Negative power supply; the device operates from 1.7 V to 5.5 V single supply (V+ - V-) or ±0.85 V to ±2.75 V dual supply, with 0.1 µF bypass recommended at each supply pin. |
| 3 | IN- | input | Negative (inverting) input of the difference amplifier, which connects to the internal precision matched resistor network. |
| 4 | OUT | output | Amplifier output, referenced to the REF pin voltage; the output swing is limited to within about 10.5 mV of V+ and 8.5 mV of V- at 10 kΩ load (INA500A, page 5), and short-circuit current is continuous-limited to ±33 mA at 5.5 V. |
| 5 | REF | input | Reference input that sets the output mid-level; it must be driven by a low-impedance source (for example a unity-gain buffer) for single-supply operation, and its input voltage range is from V- to V+ at 5.5 V. |
| 6 | V+ | power_in | Positive power supply; the device operates from 1.7 V to 5.5 V single supply (V+ - V-) or ±0.85 V to ±2.75 V dual supply, with 0.1 µF bypass recommended at each supply pin. |
