The AD7874ARZ is a 4-channel simultaneous sampling 12-bit Data Acquisition System contains a high speed 12-bit ADC, on-chip reference, on-chip clock and four track/hold amplifiers. This latter feature allows the four input channels to be sampled simultaneously, thus preserving the relative phase information of the four input channels which is not possible if all four channels share a single track/hold amplifier. This makes the AD7874 ideal for applications such as phased-array sonar and AC motor controllers where the relative phase information is important. The aperture delay of the four track/hold amplifiers is small and specified with minimum and maximum limits. This allows several AD7874 to sample multiple input channels simultaneously without incurring phase errors between signals connected to several devices. A reference output/reference input facility also allows several AD7874s to be driven from the same reference source.
● On-chip reference
● Tight aperture delay matching
● Fast microprocessor interface
