## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Amplifier A output. Rail-to-rail CMOS output stage, VOL-VSS/VDD-VOH within 6 mV of the rails at RL=100 kOhm; short-circuit current typ. +/-20 mA. |
| 2 | INA- | input | Amplifier A inverting input. High-impedance CMOS input, typ. 10 pA input bias current; common-mode range -0.1 V to VDD+0.1 V (rail-to-rail input). |
| 3 | INA+ | input | Amplifier A non-inverting input. High-impedance CMOS input, typ. 10 pA input bias current; common-mode range -0.1 V to VDD+0.1 V (rail-to-rail input). |
| 4 | VSS | power_in | Negative supply / ground. Typically tied to 0 V in single-supply operation. Absolute maximum VDD-to-VSS = 7 V; input voltage range VSS-0.5 V to VDD+0.5 V. |
| 5 | INB+ | input | Amplifier B non-inverting input. High-impedance CMOS input, typ. 10 pA input bias current; common-mode range -0.1 V to VDD+0.1 V (rail-to-rail input). |
| 6 | INB- | input | Amplifier B inverting input. High-impedance CMOS input, typ. 10 pA input bias current; common-mode range -0.1 V to VDD+0.1 V (rail-to-rail input). |
| 7 | OUTB | output | Amplifier B output. Rail-to-rail CMOS output stage, VOL-VSS/VDD-VOH within 6 mV of the rails at RL=100 kOhm; short-circuit current typ. +/-20 mA. |
| 8 | VDD | power_in | Positive supply, +2.5 V to +5.5 V single-supply operation (absolute max 7 V VDD-to-VSS). Typical quiescent current 40 uA per amplifier (80 uA total). Bypass with a local ceramic decoupling capacitor. |

## CAD (KiCad official)

- Symbol: `TP8542ARZ`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `tp8542arz-etched.step` / `tp8542arz-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tp8542arz.step` / `tp8542arz.glb` are the bare package body.
