Preliminary specification
Pre-amplifier for Hard Disk Drive (HDD)
with MR-read/inductive write heads
TDA5153
Notes
1.
Not used bits in the registers (indicated by X) are don’t care. Default data, initialized at power-up, is zero in all
registers. For V
CC
< 2.5 V, the register contents are not guaranteed.
V
th
programming uses both test mode register and compensation capacitor register. d0 in the formula above is the
LSB of the test mode register and b2 is the data bit d2 of the compensation register.
