GENERAL DESCRIPTION
The ADL5335 is a digital gain amplifier (DGA) optimized for size of 0.5 dB. The ADL5335 also features a fast attack function use in wireless transmitters. A differential input and single- where the gain can rapidly increase or decrease by the ended output facilitates a balun free connection between the application of a single pulse. broadband integrated transceivers with differential outputs and The use of a thermometer-based digital step attenuator (DSA) the RF gain blocks and drivers amplifiers with single-ended inputs. ensures that gain changes are fundamentally glitch free. The The gain is programmable via a standard Analog Devices, Inc., ADL5335 is packaged in a 4 mm × 4 mm, 16-lead LFCSP. A serial peripheral interface (SPI) port from a maximum gain of fully populated evaluation board and system demonstration 12.0 dB down to a minimum gain of −8.0 dB with a gain step platform (SDP)-based control software are available.
