ADL5202

Data Sheet Wide Dynamic Range, High Speed, Digitally Controlled VGA ADL5202 FEATURES Dual independent, digitally controlled VGAs −11.5 dB to +20 dB gain range 0.5 dB ± 0.1 dB step size 150 Ω differential input and output 7.5 dB noise figure at maximum gain OIP3 > 50 dBm at 200 MHz −3 dB upper frequency bandwidth of 700 MHz Multiple control interface options Parallel 6-bit control interface (with latch) Serial peripheral interface (SPI) (with fast attack) Gain up/down mode Wide input dynamic range Low power mode option Power-down control Single 5 V supply operation 40-lead, 6 mm × 6 mm LFCSP package APPLICATIONS Differential ADC drivers High IF sampling receivers High output power IF amplification Instrumentation GENERAL DESCRIPTION The ADL5202 is a digitally controlled, variable gain, wide bandwidth amplifier that provides precise gain control, high output IP3, and low noise figure. The excellent distortion performance and high signal bandwidth make the ADL5202 an excellent gain control device for a variety of receiver applications. The ADL5202 also incorporates a low power mode option that lowers the supply current. For wide input dynamic range applications, the ADL5202 provides a broad 31.5 dB gain range with 0.5 dB resolution. The gain is adjustable through multiple gain control interface options: parallel, serial peripheral interface, and up/down. Incorporating proprietary distortion cancellation techniques, the ADL5202 achieves a better than 50 dBm output IP3 at freque...
