Description

IC 12BIT ADC 8CH MICROPOWER 7888

The AD7888 is a high speed, low power, 12-bit ADC that oper- ates 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-and- hold 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 con- verting full power signals up to 2.5 MHz. The AD7888 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. Alter- natively, this pin can be overdriven to provide an external refer- ence voltage for the AD7888. The voltage range for this external reference is from 1.2 V 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 a 16-lead narrow body small outline (SOIC) and a 16-lead thin shrink small outline (TSSOP) package.
