3伏串行输入完整12位数模转换器AD8300数据表
分享资料个
The AD8300 is a complete 12-bit， voltage-output digital-toanalog converter designed to operate from a single +3 volt supply. Built using a CBCMOS process， this monolithic DAC offers the user low cost， and ease-of-use in single-supply +3 volt systems. Operation is guaranteed over the supply voltage range of +2.7 V to +5.5 V making this device ideal for battery operated applications. The 2.0475 V full-scale voltage output is laser trimmed to maintain accuracy over the operating temperature range of the device. The binary input data format provides an easy-to-use one-half-millivolt-per-bit software programmability. The voltage outputs are capable of sourcing 5 mA. A double buffered serial data interface offers high speed， threewire， DSP and microcontroller compatible inputs using data in （SDI）， clock （CLK） and load strobe （LD） pins. A chip select （CS） pin simplifies connection of multiple DAC packages by enabling the clock input when active low. Additionally， a CLR input sets the output to zero scale at power on or upon user demand. The AD8300 is specified over the extended industrial （–40°C to +85°C） temperature range. AD8300s are available in plastic DIP， and low profile 1.5 mm height SO-8 surface mount packages.
