• Manufacturer Part Number: sp8127ndg
• Description: High Speed Differential Apc Amplifier
• Manufacturer: Exar Corporation

ELECTRICAL/OPTICAL SPECIFICATIONS
Unless otherwise noted: Vcc = 5V, output load: R
-20C ^Ta ^ +85
*) PSRR = 20log (ûVcc/ûVout)
**) Gain Linearity = (Gain2 – Gain 1)/Gain 1, where Gain = Vout/Pin. This test is done with current injection at the
wafer level.
