AD7845SQ的中英文资料
The AD7845 is the industry's first 4-quadrant multiplying D/A converter with an on-chip amplifier. It is fabricated on the LC 2MOS process, which allows precision linear components and digital circuitry to be implemented on the same chip.
AD7845是业界第一个具有片上放大器的四象限倍增D/A转换器。它是在LC 2MOS工艺上制造的，它允许在同一芯片上实现精密线性元件和数字电路。
The 12 data inputs drive latches which are controlled by standard CS and WR signals, making microprocessor interfacing simple. For stand-alone operation, the CS and WR inputs can be tied to ground, making all latches transparent. All digital inputs are TTL and 5 V CMOS compatible.
由标准CS和WR信号控制的12个数据输入驱动锁存器，使微处理器接口简单。对于独立操作，CS和WR输入可以连接到地上，使所有锁存器透明。所有数字输入是TTL和5伏CMOS兼容。
The output amplifier can supply ±10 V into a 2k(ohm) load. It is internally compensated, and its input offset voltage is low due to laser trimming at wafer level. For normal operation, RFB is tied to VOUT, but the user may alternatively choose RA, RB or RC to scale the output voltage range.
输出放大器可以提供±10 V到2K（欧姆）负载。它是内部补偿，其输入偏移电压低，由于激光微调在晶圆级。对于正常操作，RFB绑定到VOUT，但是用户可以交替地选择RA、RB或RC来缩放输出电压范围。
