AD7888ARUZ-REEL Datasheet

Analog to Digital Converters - ADC


The AD7888ARUZ-REEL is a high speed, low power, 12-bit ADC that operates from a single 2.7 V to 5.25 V power supply. The AD7888 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 AD7888 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 AD7888ARUZ features an on-chip 2.5 V 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 AD7888 AD7888ARUZ-REEL Features • Specified for VDD of 2.7 V to 5.25 V• Flexible Power/Throughput Rate Management• Shutdown Mode: 1 A Max• Eight Single-Ended Inputs• Serial Interface: SPI™/QSPI™/MICROWIRE™/DSP Compatible• 16-Lead Narrow SOIC and TSSOP Packages AD7888ARUZ-REEL Applications • Battery-Powered Systems (Personal Digital Assistants,Medical Instruments, Mobile Communications)• Instrumentation and Control Systems• High-Speed Modems
