The ADL5336 is a pair of cascadable IF VGAs with programmable RMS detectors. It features continuous gain control range, low noise figure, and linear-in-dB gain control. The product is suitable for applications such as point-to-multipoint radios, instrumentation, and medical devices.
The ADL5336 is a dual variable‑gain amplifier (VGA) designed for cascaded IF applications up to 1 GHz. Each VGA provides 24 dB of gain control, which can be programmed for a total of 48 dB, and includes an independent square‑law detector for automatic gain control. The device is supplied from a single 5 V rail and is intended for point‑to‑multipoint radios, instrumentation, and medical equipment.
Key features include programmable gain via SPI, a power‑down mode, differential inputs and outputs, and a typical supply current of 80 mA. The handbook provides detailed specifications, pin configuration, timing diagrams, absolute maximum ratings, and typical performance curves to aid designers in integrating the ADL5336 into their systems.
