The DAC7742 is a 16-bit Digital-to-Analog Converter (DAC) that provides 16 bits of monotonic performance over the specified operating temperature range and offers a +10V, low-drift internal reference. Designed for automatic test equipment and industrial process control applications, the DAC7742 output swing can be configured in a ±10V, ±5V, or +10V range. The flexibility of the output configuration allows the DAC7742 to provide both unipolar and bipolar operation by pin strapping. The DAC7742 includes a high-speed output amplifier with a maximum settling time of 5μs to ±0.003% FSR for a 20V full-scale change and only consumes 100mW (typical) of power.
The DAC7742 features a standard 16-bit parallel interface with double buffering to allow asynchronous updates of the analog output, and data read-back to support data integrity verification prior to an update. A user-programmable reset control allows the DAC output to reset to min-scale (FFFFH) or mid-scale (7FFFH) overriding the DAC register values. The DAC7742 is available in an LQFP-48 package and three performance grades specified to operate from -40°C to +85°C.

千萬不要忽略PCB設(shè)計中線寬線距的重要性2023-07-31 22:27
想要做好PCB設(shè)計,除了整體的布線布局外,線寬線距的規(guī)則也非常重要,因為線寬線距決定著電路板的性能和穩(wěn)定性。所以本篇以RK3588為例,詳細(xì)為大家介紹一下PCB線寬線距的通用設(shè)計規(guī)則。要注意的是,布線之前須把軟件默認(rèn)設(shè)置選項設(shè)置好,并打開DRC檢測開關(guān)。布線建議打開5mil格點,等長時可根據(jù)情況設(shè)置1mil格點。PCB布線線寬01布線首先應(yīng)滿足工廠加工能力,1724瀏覽量 -
