AD737JRZ-R7 from Analog Devices, in a SOIC-8. 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. |
