DESCRIPTION
The LD3301-1, LD3301-2 are BiCMOS devices that
support a 1-channel (2-channel) GMR Preamplifier.
They are designed for use with 4-terminal magneto-
resistive recording heads, providing a low noise
GMR head amplifier, GMR bias current control, thin
film write driver, write current control, thermal
asperity detection and correction. Fast recovery mode
can be also programmed to put the chip faster in read
mode from any other existing modes. The device is
programmable for read gain, GMR resistance
measurement, and thermal asperity threshold level.
The device allows multiple channel write functions
for servo writing. Half or all of the heads can be
simultaneously selected in the servo write mode.
Features and thresholds are controlled through a
serial port interface. This product requires +3.3V or
+5V supply voltage. Available in flip-chip or TSSOP
packages.
