10bit 4ch D/A converter - BU2508FV

BU2508FV and BU2507FV are LSI's that respectively have 4ch and 6ch of 10bit R-2R type DAC.They have terminal that can set the upper limit value / the lower limit value of DAC output independently, and can easily set voltage range best fit for application.Each channel has a buffer amplifier of full swing output type with high speed output response characteristic, and can greatly shorten stability wait time.Digital input is for TTL level input, and frequency of data transfer clock is for up to 10MHz.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
