Dual 4-Channel Driver with Oscillator &

LVDS

ENA pin enables the chip, while the SEL1 pin selects the

amplitude is determined by the currents flowing into I

at WEN2-WEN2B, WEN3-WEN3B, and WEN4-WEN4B. The

oscillator is enabled when OSEN is high. The amplified I

current of the selected channel is enabled when the ENA pin

is high. The total output current is the sum of the read

current, the enabled write currents, and the oscillator current

when enabled.

Usually a voltage DAC will drive a resistor that is in series

with the I

the user to optimize the current gain for each channel.

Output write current pulses are enabled when a high is

applied to the WEN2-WEN2B, WEN3-WEN3B, or WEN-

WEN4B pin. The write current will flow to the selected

output. When SEL1 is high I

enables read and oscillator current when low.

Ordering Information

NOTE: Intersil Pb-free products employ special Pb-free material

sets; molding compounds/die attach materials and 100% matte tin

plate termination finish, which is compatible with both SnPb and

Pb-free soldering operations. Intersil Pb-free products are MSL

classified at Pb-free peak reflow temperatures that meet or exceed

the Pb-free requirements of IPC/JEDEC J Std-020B.
