Rail-to-rail output; can source/sink about ±30 mA (Vs=3 V) or ±50 mA (Vs=5 V) with closed-loop output impedance ~10-12 Ω at 1 MHz (Av=1). |+| 2 | -IN A | input | Inverting input of amplifier channel A. Rail-to-rail CMOS input; input bias current 0.2 pA typ, offset current 0.1 pA typ at 25 °C. |+| 3 | +IN A | input | Non-inverting input of amplifier channel A. Rail-to-rail input range (0 V to Vs); differential input voltage rating ±6 V. |+| 4 | V- | power_in | Negative supply / ground pin. For single-supply operation tie to GND; total supply voltage V+ to V- must be between 2.7 V and 5.5 V (absolute max 6 V). |+| 5 | +IN B | input | Non-inverting input of amplifier channel B. Rail-to-rail input range (0 V to Vs). |+| 6 | -IN B | input | Inverting input of amplifier channel B. Rail-to-rail CMOS input with pA-level bias current. |+| 7 | OUT B | output | Output of amplifier channel B. Rail-to-rail output capable of driving ±30 mA (3 V) / ±50 mA (5 V) loads. |+| 8 | V+ | power_in | Positive supply pin. Single-supply operating range 2.7 V to 5.5 V (absolute maximum 6 V). Supply current is ~500 µA per amplifier at Vs=3 V, ~750 µA per amplifier at Vs=5 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HTCSEMI |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `HT8722ARZARZ`+- `HT8722ARZBRZ`+- `HT8722ARZARMZ`+- `HT8722ARZBRMZ`+- `HT8722ARZARDZ`+- `HT8722ARZBRDZ`++## CAD (KiCad official)++- Symbol: `HT8722ARZ`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HTCSEMI datasheet](docs/ht8722arz-datasheet.pdf) (13 pp, sha256 `f3e26f623cb62249`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
