CXA3092N

CXA3092N 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 CXA3092N 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 325 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 : 6.8 Vp-p (typ) 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. Self switching damping resistance (RD = 350 Ω). Function Read, Write and Write unsafe detection for HDD, power supply ON/OFF detection.
