DAC7742中文资料具有内部基准电压的 16 位、单通道、并行接口数据手册TI规格书

描述 Description

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.
