Bare Die Product Detail: U441

N-Channel Dual Monolithic:
Monolithic Dual N-Channel JFET amplfier - High gain, wideband. U441 monolithic dual chip design reduces parasitics and gives better performance at very high frequencies while ensuring extremely tight matching.

Featuring high CMRR and low gate leakage this part is a direct replacement for Interfet, Intersil, Motorola, National / Fairchild, Philips, Vishay / Siliconix U441.

Features:

High CMRR ≥ 85dB
Low gate leakage I_GSS ≤ 1pA

Applications:

Wideband differential amplifiers
High-speed temperature compensated single-ended input amplifiers
High speed comparators
Impedance conV/√Hzerters
Vibration detectors
