CXA3510N

CXA3510N 4ch. Read/Write Amplifier for Thin Film Head of Hard Disk Drive For the availability of this product, please contact the sales office. Description The CXA3510N is a Read/Write Amplifier for the thin film head of hard disk drive and designed to handle up to 4 channel heads. Features Operate on single +5 V power supply Low power consumption Read : 85 mW Write : 115 mW + IW × 5 Idle : 8 mW Designed for two terminal thin-film or MIG heads Read amplifier emitter follower output featuring 360 times gain (typ). Differential input capacitance for Read : 6pF (typ) Input noise : 0.47 nV / √ Hz (typ) Write current range : 5 to 15 mA Differential Head voltage swing : 9 Vp-p (typ) IW Rise / Fall times : 3.7 ns (typ) (LH=540 nH, RH=25 Ω, IW=10 mA) Differential P-ECL write data input Built-in write unsafe detection circuit. Built-in Servo write function (2/4 ch). Built-in IC protection circuit for short of head to GND. Read data outputs are high impedance in write mode. Unselected head voltage is GND potential. Built-in supply voltage monitor circuit prohibits incorrect write during power on or abnormal voltage.
