Key electrical and mechanical differences between the two devices
| Parameter | AD8330ARQZ | AD8330ARQ | Why it matters |
|---|---|---|---|
| Manufacturer | Analog Devices Inc. | Analog Devices Inc. | Same manufacturer ensures consistent design, documentation, and support. |
| Function | Low noise, wideband variable gain amplifier (VGA) | Low noise, wideband variable gain amplifier (VGA) | Identical core function confirms the parts are functionally interchangeable in signal-chain designs. |
| Package / Case | 16-Lead QSOP | 16-Lead QSOP | Same package footprint allows drop-in replacement on an existing PCB layout. |
| Supply Voltage Range | 2.7 V to 6 V single supply | 2.7 V to 6 V single supply | Matching supply range ensures compatibility with the same power rail design. |
| Bandwidth | 150 MHz | 150 MHz | Equal bandwidth guarantees the same high-frequency performance in the application. |
| Gain Range | 0 dB to 50 dB | 0 dB to 50 dB | Identical gain range preserves the dynamic range and signal scaling of the circuit. |
| RoHS / Lead-Free Status | RoHS compliant, lead-free | Non-RoHS, contains lead | The "Z" suffix denotes lead-free/RoHS compliance; this affects regulatory compliance and solder process requirements. |
| Part Number Suffix Meaning | Z = RoHS-compliant lead-free version | No Z = standard leaded version | The suffix distinguishes environmental compliance and manufacturing process, which matters for procurement and assembly. |
