The AD7887 is a high speed, low power, 12-bit analog-to-digital converter (ADC) that operates from a single 2.7 V to 5.25 V power supply. The AD7887 is capable of 125 kSPS throughput rate. The input track-and-hold acquires a signal in 500 ns and features a single-ended sampling scheme. The output coding for the AD7887 is straight binary, and the part is capable of converting full power signals of up to 2.5 MHz. The AD7887 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 AD7887 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.
