AD603ARZ-REEL7 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 | GPOS | input | Gain control positive input with 50 MΩ differential input resistance, 40 dB/V scaling factor, −1.2 V to +2.0 V common-mode range, and 50-250 nA bias current. |
| 2 | GNEG | input | Gain control negative input with 50 MΩ differential input resistance, 40 dB/V scaling factor, −1.2 V to +2.0 V common-mode range, and 50-250 nA bias current. |
| 3 | VINP | input | Signal input to attenuator with 100 Ω input resistance, 1.3 nV/√Hz input noise spectral density, 2 pF input capacitance, and ±1.4 to ±2 V peak input voltage rating. |
| 4 | COMM | power_in | Amplifier common ground reference; must be connected directly to input ground with minimum impedance to avoid reducing gain accuracy. |
| 5 | FDBK | output | Feedback network connection point; leave open for +9 dB to +51 dB gain range, short to pin 7 (VOUT) for −11 dB to +31 dB range, or connect external resistor between VOUT and FDBK for intermediate ranges. |
| 6 | VNEG | power_in | Negative power supply input with −6.3 V to −4.75 V specified operating range, ±7.5 V absolute maximum rating. |
| 7 | VOUT | output | Amplifier output with ±2.5 V peak minimum into 500 Ω load, 275 V/µs slew rate, and 50 mA maximum short-circuit current. |
| 8 | VPOS | power_in | Positive power supply input with +4.75 V to +6.3 V specified operating range, 12.5-17 mA quiescent current, ±7.5 V absolute maximum rating. |
