RS721XTDE6 from Jiangsu RUNIC Tech, in a DFN-6-EP(2x2). 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; per the absolute maximum ratings, the signal output pin must stay within (V-)-0.5 V to (V+)+0.5 V, and output short-circuit current is continuous-rated. |
| 2 | V- | power_in | Negative (lowest) power supply; the supply voltage Vs = (V+) - (V-) is specified from 2.5 V to 5.5 V single-supply (absolute maximum 7 V). |
| 3 | +IN | input | Positive (noninverting) input; the signal input must stay within (V-)-0.5 V to (V+)+0.5 V, and input signals beyond 0.5 V outside the rails should be limited to 10 mA. |
| 4 | -IN | input | Negative (inverting) input; the signal input must stay within (V-)-0.5 V to (V+)+0.5 V, and input signals beyond 0.5 V outside the rails should be limited to 10 mA. |
| 5 | NC | unconnected | No internal connection; the pin can be left floating, and the datasheet notes GND is typically the recommended connection to a heat spreading plane. |
| 6 | V+ | power_in | Positive (highest) power supply; the supply voltage Vs = (V+) - (V-) is specified from 2.5 V to 5.5 V single-supply (absolute maximum 7 V). |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
