• Manufacturer Part Number: VCA2613Y
• Description: Dual, VARIABLE GAIN AMPLIFIER with Low-Noise Preamp
• Manufacturer: BURR-BROWN [Burr-Brown Corporation]

TYPICAL PERFORMANCE CURVES
At T
The input to the preamp (LNP) is single-ended, and the output from the VCA is single-ended unless otherwise noted. This results in a 6dB reduction in signal
amplitude compared to differential operation.
