Product Summary
The AD7888ARU is a high speed, low power, 12-bit ADC that operates from a single 2.7 V to 5.25 V power supply. The AD7888ARU is capable of a 125 kSPS throughput rate. The input track-andhold acquires a signal in 500 ns and features a single-ended sampling scheme. The AD7888ARU contains eight single-ended analog inputs, AIN1 through AIN8. The analog input on each of these channels is from 0 to VREF. The part is capable of converting full power signals up to 2.5 MHz. The applications of the AD7888ARU include Battery-Powered Systems (Personal Digital Assistants, Medical Instruments, Mobile Communications), Instrumentation and Control Systems, High-Speed Modems.
