Overview
CXA3541N 2-channel Read/Write Amplifier for GMR-Ind Head Hard Disk Drive Description The CXA3541N is a read/write amplifier for GMR-Ind (Giant Magneto Resistive-Inductive) heads used in hard disk drives, and is capable of supporting up to two channels.
Features • +5V and –3V power supply • Current bias voltage sense type • Low power 180mW at read • Differential read amplifier gain; ×100/135 (RMR = 50Ω) • Input noise of 0.
77nV/√ Hz (typ.
), RMR = 50Ω, IB = 5.
