Description

The CXA1829N is a Read/Write amplifier for hard disk drive thin-film heads and is designed to handle up to 8-channel heads.

Features

? Operates on a single 5V power supply.

? Low power consumption. Read: 115 mW Write (IW = 15 mA): 160 mW + IW × 5 Power Save: 7 mW

? Write current can be varied through an external resistor. Built-in stabilizer circuit provides stable current, preventing voltage and temperature drift.

? Drives up to 8 heads.

? Supports thin film heads or 2-pin MIG heads.

? Emitter follower-type Read amplifier features 290 times gain (typ.).

? Write-unsafe detection circuit.

? Damping resistance is switched at Write (315 ?).

? Simultaneous Write function.

? Supply voltage monitor circuit prohibits error writing during power surge or abnormal voltage.

? IC protection circuit for head-to-ground short circuit protection.

? Differential input capacitance at Read: 14 pF (typ.).

? Write data input minimum pulse width: 10 ns

? Read data output in Write mode becomes a high impedance due to the improved Read data offset when Write is switched to Read.

? Non-selected head DC voltage falls to GND level.
