The AD7887AR can be configured for either dual- or single-channel operation via the on-chip control register. There is a default single-channel mode that allows the AD7887AR to be operated as a read-only ADC. In single-channel operation, there is one analog input (AIN0) and the AIN1/VREF pin assumes its VREF function. This VREF pin allows the user access to the part’s internal 2.5 V reference, or the VREF pin can be overdriven by an external reference to provide the reference voltage for the part. This external reference voltage has a range of 2.5 V to VDD. The analog input range on AIN0 is 0 to VREF.

In dual-channel operation, the AIN1/VREF pin assumes its AIN1 function, providing a second analog input channel. In this case, the reference voltage for the part is provided via the VDD pin. As a result, the input voltage range on both the AIN0 and AIN1 inputs is 0 to VDD.

CMOS construction ensures low power dissipation of typically 2 mW for normal operation and 3 μW in power-down mode. The part is available in an 8-lead, 0.15-inch-wide narrow body SOIC and an 8-lead MSOP package.
