概要
Description
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.
Pinout
- 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.
