ADL5562 is a 3.3GHz ultralow distortion RF/IF differential amplifier with -3dB bandwidth 3.3GHz (AV = 6dB), pin-strappable gain adjust (6dB, 12dB, 15.5dB), differential or single-ended input to differential output, low noise input stage (2.1nV/√Hz RTI @ AV = 12dB), low broadband distortion (Av = 6dB), 10MHz:-91dBc HD2, -98dBc HD3, 70MHz:-102dBc HD2, -90dBc HD3, 140MHz:-104dBc HD2, -87dBc HD3, 250MHz:-80dBc HD2, -94dBc HD3, IMD3s of -94dBc @ 250MHz center, slew rate:9.8V/ns, fast settling 2ns and overdrive recovery 3ns, single-supply operation 3V to 3.6V, power-down control, fabricated using the high speed XFCB3 SiGe process
The ADL5562 is a high‑performance differential amplifier optimized for RF and IF applications. It offers low‑noise (2.1 nV/√Hz) and ultralow distortion across a 3.3 GHz bandwidth, with selectable gain of 6 dB, 12 dB or 15.5 dB via pin‑strapping.
The device operates from a single 3.3 V to 3.6 V supply, draws about 80 mA in normal mode (under 3 mA when disabled), and features a 9.8 V/ns slew rate with fast 2 ns settling. It is supplied in a 16‑lead LFCSP package suitable for temperatures from –40 °C to +85 °C.
| -3 dB Bandwidth | 3.3 GHz |
|---|---|
| Gain Options | 6 dB, 12 dB, 15.5 dB (pin‑strappable) |
| Input‑referred Noise | 2.1 nV/√Hz (typ) |
| Quiescent Current | 80 mA typical, <3 mA disabled |
| Slew Rate | 9.8 V/ns |
Typical quiescent current is about 80 mA, dropping to less than 3 mA when disabled.
The input noise density is 2.1 nV/√Hz at the typical gain setting.
Gain is set by pin‑strapping to 6 dB, 12 dB, or 15.5 dB.
