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 | CC | passive | Coupling Capacitor connection for indirect DC coupling to Pin 2 (VIN). Also provides an alternative low-impedance input access to an internal 8 kΩ V-to-I resistor. |+| 2 | VIN | input | High-impedance (10^12 Ω) FET RMS signal input. Accepts RMS levels up to 200 mV (up to ~1 V with ±5 V supplies); peak transient input ±0.9 V at ±2.8/-3.2 V supplies, ±2.7 V at ±5 V. |+| 3 | POWER DOWN | input | Enable/disable control. When grounded or pulled low, the AD737 is enabled; when pulled high, the part enters power-saving standby mode (~25 µA typical supply current). |+| 4 | -VS | power_in | Negative power supply. Operating range -2.5 V to -16.5 V (dual-supply operation, ±2.5 V to ±16.5 V total). |+| 5 | CAV | passive | Averaging Capacitor connection. External CAV sets the RMS averaging time constant; typical value 33 µF (100 µF for improved crest-factor performance). |+| 6 | OUTPUT | output | DC output with negative-going polarity (output is negative with respect to COM). Output resistance typically 8 kΩ. |+| 7 | +VS | power_in | Positive power supply. Operating range +2.5 V to +16.5 V (dual-supply operation, ±2.5 V to ±16.5 V total). Typical supply current ~160 µA. |+| 8 | COM | passive | Common (analog ground reference). Output voltage is measured with respect to this pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Analog Devices |+| Package | SOIC-8 |+| Category | Data Acquisition |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `AD737JRZ-R7`+- `AD737JRZ-RL`+- `AD737JRZ-R7KRZ`+- `AD737JRZ-R7KRZ-RL`+- `AD737JRZ-R7KR`+- `AD737JRZ-R7JN`+- `AD737JRZ-R7KN`+- `AD737JRZ-R7JNZ`+- `AD737JRZ-R7KNZ`++## CAD (KiCad official)++- Symbol: `AD737JRZ-R7`+- 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:** [Analog Devices datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588907273464778753) (24 pp, sha256 `477ad2bfa8ea79a9`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
