CXA3188N 2ch. Read/Write Amplifier for Thin Film Head of Hard Disk Drive For the availability of this product, please contact the sales office. Description The CXA3188N is a Read/Write Amplifier for the thin film head of hard disk drive and designed to handle up to 2 channel heads. Features Operate on single +5 V power supply Low power consumption Read : 90 mW Write : 115 mW + IW × 5 Idle : 8 mW Designed for two terminal thin-film or MIG heads. Read amplifier emitter follower output featuring 200 times gain(typ). Differential input capacitance for Read : 6pF (typ) Input noise : 0.47 nV / √ Hz (typ) Write current range : 10 to 20 mA Differential Head voltage swing : 9 Vp-p (typ) Differential P-ECL write data input. Built-in write unsafe detection circuit. Built-in Servo write function. Read data outputs are high impedance in write mode. Unselected head voltage is high impedance. Self switching damping resistor 380 Ω. Built-in supply voltage monitor circuit prohibits incorrect write during power on or abnormal voltage. Function Read, Write and Write unsafe detection for HDD, power supply ON/OFF detection.
