# RS722XTDE8

**Jiangsu RUNIC Tech** · Operational Amplifier · DFN-8(2x2)

RS722XTDE8 from Jiangsu RUNIC Tech, in a DFN-8(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 | OUTA | output | Output of channel A; the output swings rail to rail within the supply range of 2.5V to 5.5V. |
| 2 | -INA | input | Inverting input of channel A; input voltage is limited to (V-)-0.5V to (V+)+0.5V and input signals beyond 0.5V outside the rails should be current-limited to 10mA or less. |
| 3 | +INA | input | Noninverting input of channel A; input voltage is limited to (V-)-0.5V to (V+)+0.5V and input signals beyond 0.5V outside the rails should be current-limited to 10mA or less. |
| 4 | V- | power_in | Negative (lowest) power supply; single-supply operation is specified from 2.5V to 5.5V with an absolute maximum supply of 7V. |
| 5 | +INB | input | Noninverting input of channel B; input voltage is limited to (V-)-0.5V to (V+)+0.5V and input signals beyond 0.5V outside the rails should be current-limited to 10mA or less. |
| 6 | -INB | input | Inverting input of channel B; input voltage is limited to (V-)-0.5V to (V+)+0.5V and input signals beyond 0.5V outside the rails should be current-limited to 10mA or less. |
| 7 | OUTB | output | Output of channel B; the output swings rail to rail within the supply range of 2.5V to 5.5V. |
| 8 | V+ | power_in | Positive (highest) power supply; single-supply operation is specified from 2.5V to 5.5V with an absolute maximum supply of 7V. |
