The ADL5310 is a low-cost dual logarithmic amplifier that converts input current over a wide dynamic range to a linear-in-dB output voltage. It is optimized for the determination of optical power in wide-ranging optical communication system applications including control circuitry for lasers, optical switches, attenuators, and amplifiers, as well as general system monitoring. The device is equivalent to a dual AD8305 with enhanced dynamic range (120 dB). While the ADL5310 contains two independent signal channels with individually-configurable transfer function constants (slope and intercept), internal bias circuitry is shared between channels for improved power consumption and channel matching. Dual converters in a single compact LFCSP package yield space-efficient solutions for measuring gain or attenuation across optical elements. Only a single supply is required, while optional dual supply operation offers added flexibility.The ADL5310 employs an optimized translinear structure, which utilizes the accurate logarithmic relationship between a bipolar transistor's base-emitter voltage and collector current, with appropriate scaling by precision currents to compensate the inherent temperature dependence. Input and reference current pins sink current ranging from 3 nA to 3 mA (limited to ?60 dB between input and reference) into a fixed voltage defined by the VSUM potential, which is internally set to 500 mV but may be externally-grounded for dual-supply operation and additional applications requiring voltage inputs.

The ADL5324 incorporates a dynamically adjustable biasing circuit that allows for the customization of OIP3 and P1dB performance from 3.3 V to 5 V, without the need for an external bias resistor. This feature gives the designer the ability to tailor driver amplifier performance to the specific needs of the design. This feature also creates the opportunity for dynamic biasing of the driver amplifier where a variable supply is used to allow for full 5 V biasing under large signal conditions, and then reduced supply voltage when signal levels are smaller and lower power consumption is desirable. This scalability reduces the need to evaluate and inventory multiple driver amplifiers for different output power requirements, from 25 dBm to 29 dBm output power levels.The ADL5324 is also rated to operate across the wide temperature range of ?40?C to +105?C for reliable performance in designs that experience higher temperatures, such as power amplifiers. The ? W driver amplifier also covers the wide frequency range of 400 MHz to 4000 MHz, and only requiresa few external components to be tuned to a specific band within that wide range.

The 50 ? differential input system converts the applieddifferential voltage at INHI and INLO to a pair of differentialcurrents with high linearity and good common-mode rejection. The signal currents are then applied to a proprietary voltage-controlled attenuator providing precise definition of the overall gain under the control of the linear-in-dB interface.

The ADL5390 vector multiplier consists of a matched pair of broadband variable gain amplifiers whose outputs are summed. The separate gain controls for each amplifier are linear-in-magnitude. If the two input RF signals are in quadrature, the vector multiplier can be configured as a vector modulator or as a variable attenuator/phase shifter by using the gain control pins as Cartesian variables. In this case, the output amplitude can be controlled from a maximum of +5 dB to less than -30 dB, and the phase can be shifted continuously over the entire 360? range. Since the signal paths are linear, the original modulation on the inputs is preserved. If the two signals are independent, then the vector multiplier can function as a 2:1 multiplexer or can provide fading from one channel to another.The ADL5390 operates over a wide frequency range of 20 MHz to 2400 MHz.
