DESCRIPTION
The MB4138 is a 6-channel read/write amplifier IC for magneto-resistive (MR) and inductive thin film composite
heads used in hard disk drives.
I
FEATURES
Drives six MR and thin film composite heads.
The bias current for the MR head can be set in the range of 5 to 12 mA (DC).
The read signal from the MR head is directly connected to the internal differential amplifier.
High gain (
×
150), low noise (0.51 nV/
Hz
) read amplifier
Read amplifier output buffer type: open collector.
Voltage output function pin for MR heads (VHR)
VHR pin ground fault protection function
Read output voltage stabilization at mode switching
Psuedo-ECL level differential input for write data
The write current can be set in the range from 10 to 40 mA (DC).
Internal write-unsafe detect circuit. Detects write head faults.
(For HDD MR and thin film composite heads, 6 channels)
