Description

The PGA5 Series programmable amplifiers are digitally controlled gain modules that were designed for Frequency Devices’ multi-channel VME board products to condition DC-coupled wide-band signals. They are programmed by an 8-bit serial data stream for gain selection using clock, data and strobe inputs. Other standard performance features include differential input, single ended output, 5V interface logic and low noise/distortion. Available options include AC coupled input (all models) and/or differential output (VM32PA) only. Features/Benefits: Phase match of ±1.0º for the PGA5-100 and ±2.0º for the PGA5-2.0 with Gain accuracy of ±0.1 dB provides precision performance solutions to design engineers, system integrators and OEM’s.

• Offers a low cost, versatile and convenient way to provide up to 32 channels of precision amplification in a single width B-size (6U) VME form factor. Available Amplifier Options: VM32PA-PGA5-100 -12 dB to +60 dB in 6 dB steps for frequencies to 100 kHz VM32PA2.0-PGA5-2.0-12 dB to +36 dB in 6 dB steps for frequencies to 2.0 MHz
