AD7782和AD7783均为24位、低成本、低功耗Σ-Δ型ADC,适合直流和低频交流测量应用。二者均为只读ADC,无可写寄存器,这使得ADC与控制器之间的接口非常简单。由于这些器件的功耗很低,因此可以采用环路供电、电池供电或本地供电方式。双设置片内可编程增益放大器(PGA)无需外部信号调理硬件,便可处理低电平或高电平模拟输入。工作选项可通过引脚编程(非软件编程)来实现。
The AD7782 and AD7783 are 24-bit low cost, low power Sigma Delta ADCs intended for dc and low frequency ac measurement applications. They are Read-only ADCs and have no writeable registers. This leads to a very simple interface between ADC and controller. Since their power consumption is low, the devices can be loop powered, battery powered or locally powered. The two-setting on-chip PGA can accommodate either a low-level or high-level analog input with no external signal conditioning hardware. Operating options are pin-programmable, not software programmable.
