VM32PA-PGA5-100

PGA5 Series for FDI VME Boards 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. Programmable Amplifiers 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 25 Locust St, Haverhill, Massachusetts 01830 • Tel: 800/252-7074, 978/374-0761 • FAX: 978/521-1839 e-mail: sales@freqdev.com • Web Address: http://www.freqdev.com PGA5 Series for FDI VME Boards PGA5-100 Frequency Response 70 40 60 Programmable Amplifiers PGA5-2.0 Frequency Response 50 30 Gain (dB) Gain (dB) 10 100 1000 10000 100000 40 20 30 20 10 10 0 0 -10 -10 -20 -20 100 1000 10000 100000 1000000 Frequency (Hz) Frequency (Hz) Common Mode Rejection Ratio 0 0 -10 -20 -20 -30 -40 -50 -60 -70 -80 -100 -90 -120 10 100 1000 10000 100000 -100 100 Common Mode Rejection Ratio CMRR (dB) -40 -60 -80 CMRR (dB) 1000 10000 100000 1000000 10000000 Frequency (Hz) Frequency (Hz) Noise -60 -70 -60 Noise RTI Noise density (dBVrms/√Hz) -80 -90 -100 -110 -120 -130 -140 -150 -160 -12 0 12 24 36 48 60 RTI Noise density (dBVrms/√Hz) -80 -100 -120 -140 -160 -180 -12 0 12 24 36 Gain (dB) Measured at 51.2 kHz Gain (dB) Measured at 51.2 kHz 2 25 Locust St, Haverhill, Massachusetts 01830 • Tel: 800/252-7074, 978/374-0761 • FAX: 978/521-1839 e-mail: sales@freqdev.com • Web Address: http://www.freqdev.com PGA5 Series Specification (25°C and rated power input) VME Board Analog Input Configuration Impedance Bias Current Offset Current Safe Voltage Linear Input Range CMRR AC Couple (Optional Fixed Freq.)
