AD603ARZ-REEL7

Analog Devices · Low Noise Amplifiers (LNA) - RF · SOIC-8

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.
