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.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
