2 CHANNEL BRIDGE DRIVER IC
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
The NJW4301 is a 2 channel bridge driver for CD, CD-ROM, MO
and others. It operates at more than 4V, and then features high
output voltage swing.
Its output circuit consists of MOS-FET. The MOS-FET type output
realizes lower consumption than bipolar type output, so that
radiation design becomes simple and total costs are reduced.
■ FEATURES
● Operating Voltage (V+=4V to 12V)
● Low Saturation Output (Vsat=±0.5VMAX. at IO=300mA)
● Supply Current (35mA MAX.)
● 2 channel BTL Output
● Mute Function
● Bi-MOS Technology
● Package Outline DIP16, SDMP30
