The AD7888BRZ is a high speed, low power 12-bit Analog-to-digital Converter (ADC) that operates from a single 2.7 to 5.25V power supply. The converter is capable of a 125kSPS throughput rate. The input track-and-hold acquires a signal in 500ns and features a 1-ended sampling scheme. The converter 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 2.5MHz. 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 converter. The voltage range for this external reference is from 1.2V to VDD. CMOS construction ensures low power dissipation of typically 2mW for normal operation and 3µW in power-down mode.
