FEATURES
12 channels design for Single-stripe (SAL and GMR) Read / Thin-film Write heads.
Design target 350 Mbps, for d=0 (16 / 17) rate code.
Differential Hybrid sense Reader architecture.
MR element biased by direct programmable constant Power or constant Current.
Voltage driven Writer architecture.
MR read / inductive write heads biased at ground level.
Short rise and fall time with near rail to rail voltage swing.
Dual power supplies : +5.0 V and -5.0 V.
On-chip AC couplings eliminate MR head DC and DC offset voltage.
Programmable 3-wire Serial Port Interface for programming (3.3 V and 5 V TTL / CMOS compatible).
Extensive programmability of Write current wave overshoot.
Programmable voltage / current mode write data input.
Programmable voltage / current mode read data output.
Programmable Read gain.
Programmable Reader input impedance.
Thermal asperity detection with programmable threshold.
Thermal asperity compression with extensive programmability.
High spurious-noise rejections.
Internal Dummy Head available for MR heads protection during switchings.
FAST mode available for short Write to Read mode transient.
Sleep, Standby, Active, Servo Track Write, and Test modes available.
Support servo writing.
Write / Read Fault detection with fault code read back register and Fault masking capability.
Low power-supplies fault protections.
Short Write to Read Recovery, including DC settling.
On-chip digitizing of Temperature and MR element Resistance value.
Vendor ID and chip revision register.
Illegal Multiple Device Selected detection.
2 pads CS0 and CS1, hard wired, for separate activation for multiple pre-amplifiers operation.
Requires one external resistor.
