BA6302AF中文资料罗姆数据手册PDF规格书

The BA6302A/AF and BA6303/F are FG-system servo control ICs suitable for controlling the speed of VCR motors. They contain a hysteresis FG amplifier section, an S / H system F / V conversion section, an error amplifier section, and an inverter section. Motor speed can be set with a high degree of freedom by an external CR. The start-up circuit allows quick and precise motor starting. Motor speed can be controlled precisely at different levels by installing an FG program counter between the FG amplifier output and the F / V conversion input.

Features

1) S / H system F / V converter allows speed setting with a stable external CR.

2) High hysteresis FG amplifier with high noise resistance.

3) Start-up circuit allows quick and precise motor starting.

4) Motor speed can be controlled at different levels by installing an FG program counter.

5) Low current dissipation. (VCC=9V, IQ=2.3mA Typ.)

6) Stable operation with either 5, 9, or 12V supply voltage.

7) Two versatile inverters are built in.

Applications

Speed control of various motors including capstan motors, drum head motors, and reel motors
