AD7888ARUZ-REEL

AD7888 is a high speed, low power, 12bit ADC that operates from a single 2.7V to 5.25V power supply. It is capable of a 125kSPS throughput rate. The input track-and-hold acquires a signal in 500ns and features a single-ended sampling scheme. It contains eight single-ended analogue inputs, AIN1 through AIN8. The analogue input on each of these channels is from 0 to VREF. The part is capable of converting full power signals upto 2.5MHz. It features an on-chip 2.5V reference that can be used as the reference source for the A/D converter. The REF IN/REF OUT pin allows the user access to this reference. Alternatively, this pin can be overdriven to provide an external reference voltage for the device. The voltage range for this external reference is from 1.2V to VDD. It is used in applications such as battery-powered systems (personal digital assistants, medical instruments, mobile communications), instrumentation and control systems, high-speed modems.
