HMC960LP4E (ANALOG DEVICES)

The HMC960LP4E is a DC to 100MHz digitally programmable 2-channel Variable Gain Amplifier with driver. It supports discrete gain steps from 0 to 40dB in precise 0.5dB 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 100R differential or 400R 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). The HMC960LP4E requires minimal external components and provides a low cost alternative to more complicated switched amplifier architectures.
