PGA5 Series for FDI VME Boards Programmable Amplifiers 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. 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 • 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. 25 Locust St, Haverhill, Massachusetts 01830 • Tel: 800/252-7074, 978/374-0761 • FAX: 978/521-1839 e-mail: [email protected] • Web Address: http://www.freqdev.com PGA5 Series for FDI VME Boards Programmable Amplifiers PGA5-100 PGA5-2.0 Frequency Response Frequency Response 70 40 60 30 40 Gain (dB) Gain (dB) 50 30 20 10 20 10 0 0 -10 -10 -20 10 100 1000 10000 -20 100 100000 1000 Frequency (Hz) 10000 100000 1000000 Frequency (Hz) Common Mode Rejection Ratio Common Mode Rejection Ratio 0 0 -10 -20 -30 CMRR (dB) CMRR (dB) -20 -40 -60 -80 -40 -50 -60 -70 -80 -100 -90 -120 10 100 1000 10000 -100 100 100000 1000 Frequency (Hz) 10000 100000 1000000 10000000 Frequency (Hz) Noise Noise -60 -60 RTI Noise density (dBVrms/√Hz) RTI Noise density (dBVrms/√Hz) -70 -80 -90 -100 -110 -120 -130 -140 -80 -100 -120 -140 -160 -150 -180 -160 -12 0 12 24 36 48 -12 60 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: [email protected] • Web Address: http://www.freqdev.com PGA5 Series Programmable Amplifiers For VME Boards Specification (25°C and rated power input) VME Board Analog Input Configuration Impedance Bias Current Offset Current Safe Voltage Linear Input Range CMRR VM32PA PGA5-100 VM32PA2.0 PGA5-2.0 DC coupled, differential input 1 MΩ/22pF 20 pA max. 10 pA max. ±15V 8V pk, each leg Typ. 80 dB @ 1 kHz min. 60 dB, 10 Hz to 100 kHz 10Hz to 1.0kHz DC coupled, differential input 1 MΩ/22pF 10 pA max. 10 pA max. ±10V 8V pk, each leg ≥50 dB, DC to 100 kHz ≥40dB,100kHz to 2MHz 20Hz to 1.0k Hz Single ended, DC coupled Optional <1Ω typ., 10Ω max. ±5V, Output clamped to ±9V <-100dB @ 1 kHz, <-90dB @ 20 kHz ±5 mA 2mV RTI, NTE 40 mV max. ±(5+ 100/G) µV/ºC Single ended, DC coupled NA 1Ω typ., 10Ω max. ±5V, Output clamped to ±9V <-100dB @ 1 kHz, <-90dB @ 20 kHz ±5 mA <25 mV typ.
