OPA2344EA 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 to within 1 mV of supply rails with RL ≥ 100 kΩ (AOL ≥ 96 dB); short-circuit current ±15 mA continuous. |
| 2 | -In A | input | Inverting input of amplifier A; input bias current ±0.2 pA typ / ±10 pA max; differential input impedance 10¹³ Ω ∥ 3 pF; signals more than 0.5 V beyond supply rails must be current-limited to 10 mA. |
| 3 | +In A | input | Non-inverting input of amplifier A; rail-to-rail common-mode voltage range -0.3 V to (V+)+0.3 V; CMRR 76 dB min / 92 dB typ at VS = 5.5 V outside transition region. |
| 4 | V- | power_in | Negative power supply (ground reference); single-supply operating range 2.5 V to 5.5 V; absolute maximum supply voltage V+ to V- = 7.5 V. |
| 5 | +In B | input | Non-inverting input of amplifier B; rail-to-rail common-mode voltage range -0.3 V to (V+)+0.3 V; CMRR 76 dB min / 92 dB typ at VS = 5.5 V outside transition region. |
| 6 | -In B | input | Inverting input of amplifier B; input bias current ±0.2 pA typ / ±10 pA max; differential input impedance 10¹³ Ω ∥ 3 pF; signals more than 0.5 V beyond supply rails must be current-limited to 10 mA. |
| 7 | Out B | output | Rail-to-rail output of amplifier B; swings to within 1 mV of supply rails with RL ≥ 100 kΩ (AOL ≥ 96 dB); short-circuit current ±15 mA continuous. |
| 8 | V+ | power_in | Positive power supply; specified operating range 2.7 V to 5.5 V; quiescent current 150 µA typ / 250 µA max per amplifier at VS = 5.5 V; bypass with 0.01 µF ceramic capacitor. |
