Product Details

Description



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 ½).
• 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.
