Product Details
●The HMC960LP4E is a digitally programmable dual channel variable gain amplifier. It supports discrete gain steps from 0 to 40 dB in precise 0.5 dB steps. It features a glitch free architecture to provide exceptionally smooth gain transitions. The device has matched gain paths which provide excellent quadrature balance over a wide signal bandwidth.
●The HMC960LP4E provides an SPI programmable input impedance of 100Ω differential or 400Ω differential (default).
●Externally controlled common mode output feature enables the HMC960LP4E to provide a flexible output interface to other parts in the signal path. Gain can be controlled via either a parallel interface (GC[6:0]) or via the read/write serial port (SPI).
●Housed in a compact 4x4mm (LP4) SMT QFN package, the HMC960LP4E requires minimal external components and provides a low cost alternative to more complicated switched amplifier architectures.
