CXA1940N規(guī)格書詳情
Description
The CXA1940N is a Read/Write Amplifier for the thin film head of hard disk drives and designed to handle up to 4-channel heads.
Features
? Operate on single +5V power supply.
? Low power consumption.
Read : 95mW
Write (IW=20mA) : 130mW+IW × 5
Power save : 5.5mW
? Write current can be varied through an external resistor. Built-in stabilizing circuit provides stable current during voltage and temperature drift.
? Drives up to 4 heads.
? Designed for two-terminal thin-film or MIG heads.
? Built-in power save function.
? Read amplifier emitter follower output featuring 290 times gain (Typ.).
? Built-in Write unsafe detection circuit.
? Built-in supply voltage monitor circuit prohibits incorrect Write during power on or abnormal voltage.
? Built-in IC protection circuit for short of head and GND.
? Differential input capacitance for Read : 14pF (Typ.).
? Write data input minimum pulse width : 10ns
? Read data output become high impedance in write mode to improve read data offset when switching from write to read mode.
? Unselected head DC voltage is GND potential.
? Self switching damping resistance (RD=310?)
Function
Read, Write and Write unsafe detection for HDD, Power supply ON/OFF detection.
