OPA2313IDGKR from Texas Instruments, in a VSSOP-8. 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 A | output | Rail-to-rail output of amplifier A; swings within 5mV (typ) of either supply rail at RL=100kΩ; short-circuit current ±6mA (VS=1.8V) to ±15mA (VS=5.5V). |
| 2 | -IN A | input | Inverting input of amplifier A; input bias current ±0.2pA typ (±10pA max at 25°C); common-mode range (V−)−0.2V to (V+)+0.2V; input current must be limited to ±10mA if driven beyond supply rails. |
| 3 | +IN A | input | Non-inverting input of amplifier A; includes internal RF/EMI low-pass filter (~35MHz, −3dB); input bias current ±0.2pA typ (±10pA max at 25°C); common-mode range (V−)−0.2V to (V+)+0.2V. |
| 4 | V- | power_in | Negative power supply (ground reference); rated 1.8V to 5.5V single supply (±0.9V to ±2.75V split supply); bypass with 0.01µF ceramic capacitor to V+. |
| 5 | +IN B | input | Non-inverting input of amplifier B; includes internal RF/EMI low-pass filter (~35MHz, −3dB); input bias current ±0.2pA typ (±10pA max at 25°C); common-mode range (V−)−0.2V to (V+)+0.2V. |
| 6 | -IN B | input | Inverting input of amplifier B; input bias current ±0.2pA typ (±10pA max at 25°C); common-mode range (V−)−0.2V to (V+)+0.2V; input current must be limited to ±10mA if driven beyond supply rails. |
| 7 | OUT B | output | Rail-to-rail output of amplifier B; swings within 5mV (typ) of either supply rail at RL=100kΩ; short-circuit current ±6mA (VS=1.8V) to ±15mA (VS=5.5V). |
| 8 | V+ | power_in | Positive power supply; rated 1.8V to 5.5V; quiescent current 50µA/ch typ (60µA/ch max) at 25°C; bypass with 0.01µF ceramic capacitor to V−. |
