15. IC8201 (VHIBD8143MU-1Y)
High-accuracy gradation voltage generation IC with a built-in DAC
The high-accuracy gradation voltage generation IC with a built-in DAC, BD8143MUV, has a built-in 1chip integrating the setting value control by the
serial signal, high-accuracy 10bit DAC and buffer amp.
Description:
• Reduced number of parts due to 1chip
• Built-in 10bit DAC
• DAC output buffer amp (12ch)
• Amplifier input/output switching function (CTL)
• 3-wire serial interface
• Temperature protection circuit
• Power ON reset circuit
