4-channel Ultra Low Power Gmr-tmr Preamplifier For Hdd ApplicationsThe L6440 is a BICMOS Silicon Germanium
monolithic integrated circuit differential
preamplifier for Ultra Low Power Hard Disk Drive
applications.
This part is specially designed to have minimum
dissipation in all the modes of operation (Sleep
<200mW, Read <60mW, Write <200mW) and
very fast Sleep to Read recovery time (S2R
<500ns).
It is designed for use with 4-terminal Giant
Magneto Resistance / Tunnel Magneto
Resistance read and Perpendicular write heads.
In read mode, the device consists of a fully
Differential Amplifier offering: current or voltage
bias, voltage-sense input, programmable input
impedance, a wide-range read gain, low-noise
and high-bandwidth. In write mode, it includes fast
current switching differential write drivers, which
support data rates up to 600 Mb/s, overshoot
amplitude and duration programmability. In all the
modes of operations Fly Height Control circuit is
available. This circuit delivers an accurate
programmable voltage or power to a resistive
element near the write head to match write
current induced heating and subsequent
expansion or protrusion of the pole tip which
effect the media spacing. By STMicroelectronics
