Philips Semiconductors

Preliminary specification

Pre-amplifier for Hard Disk Drive (HDD)

with MR-read/inductive write heads

TDA5153

9

LIMITING VALUES

In accordance with the Absolute Maximum Rating System (IEC 134).

10 HANDLING

Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is

desirable to take normal precautions appropriate to handling MOS device.

11 THERMAL CHARACTERISTICS

Note

1. The TDA5153X is shipped in naked dies. The thermal resistance depends on the flex used.
