RS321BPXC5 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 voltage range is -0.2 V to 5.7 V when VS = 5.5 V, and inputs that swing more than 0.5 V beyond the supply rails should be current-limited to 10 mA or less. |
| 2 | V- | power_in | Negative (lowest) power supply; VS = (V+) - (V-) must stay within 2.1 V to 5.5 V single-supply (or ±1.05 V to ±2.75 V dual-supply), and the 7 V absolute maximum must not be exceeded. |
| 3 | -IN | input | Negative (inverting) input; inputs that swing more than 0.5 V beyond the supply rails should be current-limited to 10 mA or less. |
| 4 | OUT | output | Output; outputs that swing more than 0.5 V beyond the supply rails should be current-limited to ±100 mA or less, and output short-circuit to ground is continuous for one amplifier per package. |
| 5 | V+ | power_in | Positive (highest) power supply; VS = (V+) - (V-) must stay within 2.1 V to 5.5 V single-supply (or ±1.05 V to ±2.75 V dual-supply), and the 7 V absolute maximum must not be exceeded. |
