Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | OUT A | output | Amplifier A output. Rail-to-rail CMOS output stage; short-circuit current +/-18 mA typical; open-loop output resistance 120 ohm at 1 MHz; drives up to 1 nF capacitive load. |+| 2 | -IN A | input | Amplifier A inverting input. High-impedance CMOS input (100 MOhm || 6 pF differential); input bias current typ +/-160 pA; diode-clamped to supply rails, limit external current to 10 mA if exceeding rails by >0.5 V. |+| 3 | +IN A | input | Amplifier A non-inverting input. Input common-mode range extends from V- to (V+)-1.5 V; input bias current typ +/-160 pA; diode-clamped to supply rails. |+| 4 | V- | power_in | Negative supply rail. Single-supply operation: connect to GND (0 V) with V+ from +4 V to +36 V. Dual-supply operation: -2 V to -18 V. Bypass locally with 0.1 uF close to the pin. Shared between both amplifiers A and B. |+| 5 | +IN B | input | Amplifier B non-inverting input. Input common-mode range extends from V- to (V+)-1.5 V; input bias current typ +/-160 pA; diode-clamped to supply rails. |+| 6 | -IN B | input | Amplifier B inverting input. High-impedance CMOS input (100 MOhm || 6 pF differential); input bias current typ +/-160 pA; diode-clamped to supply rails, limit external current to 10 mA if exceeding rails by >0.5 V. |+| 7 | OUT B | output | Amplifier B output. Rail-to-rail CMOS output stage; short-circuit current +/-18 mA typical; open-loop output resistance 120 ohm at 1 MHz; drives up to 1 nF capacitive load. |+| 8 | V+ | power_in | Positive supply rail. Operating range +4 V to +36 V single-supply (or +2 V to +18 V dual). Quiescent current 415 uA per amplifier typ (475 uA max) at Vs = +/-18 V. Bypass locally with 0.1 uF close to the pin. Shared between both amplifiers A and B. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `OPA2188AIDRAID`+- `OPA2188AIDRAIDR`+- `OPA2188AIDRAIDGKT`+- `OPA2188AIDRAIDGKR`++## CAD (KiCad official)++- Symbol: `OPA2188AIDR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/opa2188a.pdf) (28 pp, sha256 `18cd8026c26eeda7`, retrieved 2026-08-17, tier: manufacturer)+- **Datasheet language:** Chinese.
