RS721XF from Jiangsu RUNIC Tech, in a SOT-23-5. 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 | OUT | output | Amplifier output; absolute maximum output current is ±100 mA, output short-circuit is continuous (one amplifier per package to ground), and outputs are diode-clamped to the supply rails. |
| 2 | V- | power_in | Negative (lowest) power supply; single-supply operation spans 2.5 V to 5.5 V between V+ and V-, and the absolute maximum supply voltage is 7 V. |
| 3 | +IN | input | Positive (noninverting) input; common-mode range is -0.1 V to 5.6 V at Vs = 5.5 V, and the signal input is absolute-maximum limited to (V-) - 0.5 V to (V+) + 0.5 V with ±10 mA current limit. |
| 4 | -IN | input | Negative (inverting) input; common-mode range is -0.1 V to 5.6 V at Vs = 5.5 V, and the signal input is absolute-maximum limited to (V-) - 0.5 V to (V+) + 0.5 V with ±10 mA current limit. |
| 5 | V+ | power_in | Positive (highest) power supply; single-supply operation spans 2.5 V to 5.5 V above V-, and the absolute maximum supply voltage is 7 V. |
