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 Ω).
● 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.
