产品详情
- 12位CMOS MDAC、内置输出放大器
- 四象限乘法
- 低功耗LC2MOS
- 保证单调性(Tmin至Tmax)
- 0.3" DIPS以及24或28引脚表面贴装封装，节省空间
- 片内应用电阻用于增益范围调整等功能
AD7845是业界首款内置片内放大器的四象限乘法数模转换器。它采用LC2MOS工艺制造，可以在同一芯片上集成精密线性元件与数字电路。
12路数据输入可驱动由标准CS与WR信号控制的锁存器，从而与微处理器实现轻松接口。独立工作时，CS与WR输入可以接地，使所有锁存器能够透明操作。所有数字输入均为TTL和5 V CMOS兼容。
输出放大器可以向2 kΩ负载提供±10 V电压。它采用内部补偿，而且在晶圆水平上进行激光调整，因此其输入失调电压较低。正常工作时，RFB连至VOUT，但用户也可以选择RA、 RB 或RC来调整输出电压范围。
