RS721BPXC5 from Jiangsu RUNIC Tech, in a SC70-5. 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 | +IN | input | Positive (noninverting) input; the common-mode input range is -0.2V to 5.7V with Vs = 5.5V. |
| 2 | V- | power_in | Negative (lowest) power supply; the device operates from a 2.5V to 5.5V single supply (or ±1.25V to ±2.75V dual supply). |
| 3 | -IN | input | Negative (inverting) input; input pins are diode-clamped to the supply rails, and signals that swing more than 0.5V beyond the rails should be limited to 10mA or less. |
| 4 | OUT | output | Output; output signals that swing more than 0.5V beyond the supply rails should be current-limited to ±150mA or less. |
| 5 | V+ | power_in | Positive (highest) power supply; the absolute maximum supply voltage is 7V, and a 0.1uF capacitor should be placed closely across the supply pins. |
