  • RE: PGA855: Can PGA855 drive ADC with sampling rate > 1 MSPS?

    Resolved
    Hi David, Yes, the THS7001 (100-MHz (-3dB), Slew Rate=175 V/µs) high-speed PGA we are trying to replace is an order of magnitude faster than the PGA855. The PGA855 (10-MHz, Slew Rate = 35V/ µ s) is not considered a high-speed amplifier; this is…
