Overview
The ADL5240ACPZ-R7, produced by Analog Devices Inc., is a high-performance, digitally controlled variable gain amplifier (VGA) designed for operation in the frequency range of 100 MHz to 4000 MHz. This component integrates a high-gain, internally matched amplifier with a 6-bit digital step attenuator (DSA), offering a gain control range of 31.5 dB in 0.5 dB steps with ±0.25 dB step accuracy. The ADL5240 is packaged in a thermally efficient, 5 mm × 5 mm, 32-lead LFCSP and is fully specified for operation from −40°C to +85°C, making it suitable for a variety of RF and IF applications.
