A/D, D/C Converters for Image Signal Processing MN6570F, MN6570TF, and MN6570EF Low Power 8-Bit, 3-Channel CMOS D/A Converters for Image Processing Overview The MN6570F, MN6570TF, and MN6570EF are highspeed 8-bit, 3-channel CMOS digital-to-analog converters with maximum conversion rates of 35 MSPS, 40 MSPS, and 40 MSPS, respectively. They use both a matrix cell and weighted current technology. The three channels use separate clock signals, so they may be used as totally independent D/A converters.

(5) When designing your equipment, comply with the range of absolute maximum rating and the guaranteed operating conditions (operating power supply voltage and operating environment etc.). Especially, please be careful not to exceed the range of absolute maximum rating on the transient state, such as power-on, power-off and mode-switching. Otherwise, we will not be liable for any defect which may arise later in your equipment. Even when the products are used within the guaranteed values, take into the consideration of incidence of break down and failure mode, possible to occur to semiconductor products. Measures on the systems such as redundant design, arresting the spread of fire or preventing glitch are recommended in order to prevent physical injury, fire, social damages, for example, by using the products. (6) Comply with the instructions for use in order to prevent breakdown and characteristics change due to external factors (ESD, EOS, thermal stress and mechanical stress) at the time of handling, mounting or at customer's process. When using products for which damp-proof packing is required, satisfy the conditions, such as shelf life and the elapsed time since first opening the packages.
