AD8330-EVALZ Datasheet PDF - ADI

●The AD8330-EVALZ is a wideband variable gain amplifier evaluation board for applications requiring a fully differential signal path, low noise, well defined gain, and moderately low distortion from DC to 150MHz. The EVAL-AD8330EB is an easy to use accessory that enables a hands on evaluation of the AD8330 variable gain amplifier (VGA). It includes test pins for connections to all of the functional device inputs. The input SMA connector IN is terminated with a 49.9ohm resistor. For convenience the board includes an AD8131 high speed differential amplifier to convert a single ended signal source to the differential input of the AD8330. If desired, the AD8131 can be removed and the AD8330 can be driven at one of its inputs from a single ended source. The AD8330 output is observed at the SMA connectors or by using the 2 pin header adjacent to the device.

● Fully differential signal path, also used with single sided signals

● Inputs from 0.3mV to 1Vrms, rail to rail outputs

● Differential RIN is 1Kohm and ROUT (each output) is 75ohm

● Linear in dB and linear in magnitude gain modes

● Inverted gain mode of 50dB to 0dB at -30mV/dB

● Constant bandwidth of 150MHz at all gains

● Low noise of 5nV/√Hz typical at maximum gain

● Low distortion of less than or equal to 62dBc

● Low power consumption of 20mA typical at VS of 2.7V to 6V

●ESD sensitive device, take proper precaution while handling the device.
