AD8335ACPZ

AD8335ACPZ is Analog Devices’ high-performance variable gain amplifier (VGA) for RF front ends. It provides programmable gain over a wide dynamic range with low noise and distortion, enabling automatic gain control and signal level management before ADCs or demodulators. The device combines an RF gain stage with an attenuator and is controlled via a serial/pin interface. It comes in a RoHS-compliant ACPZ package suitable for compact layouts. Applications include wireless receivers, radar, instrumentation, and test equipment where adjustable gain, wide bandwidth, and good linearity are needed. For exact specifications—gain range, bandwidth, noise figure, linearity, supply current, and control protocol—see the AD8335ACPZ datasheet and evaluation guides.

- Pin count: 28 pins (ACPZ package).
- Function: Analog Devices AD8335 is a wideband RF front-end: a dual-channel I/Q mixer with a programmable-gain amplifier (VGA) for downconversion and baseband demodulation in receiver chains. It provides LO inputs, I/Q inputs/outputs, and gain control.

Analog Devices, Inc. (ADI) is the manufacturer. It is a multinational American semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing (DSP) integrated circuits for a wide range of industries.

Applications of AD8335ACPZ:
- RF receivers and transceivers as a broadband VGA/IF gain stage (cellular, WLAN, microwave links).
- Automatic gain control (AGC) loops in wireless front-ends needing programmable gain and wide dynamic range.
- RF instrumentation and test equipment preamplifier/conditioning (spectrum analyzers, RF signal generators, etc.).
- Radar and satellite communication receiver front-ends.
- Defense/aerospace RF systems and avionics subsystems.
- Any system requiring wide dynamic range RF signal conditioning and programmable gain in the front-end.

AD8335ACPZ is in an 8‑lead MSOP (Micro Small Outline Package), RoHS compliant.
