T he AD7874 is a four-channel simultaneous sampling, 12-bit  
data acquisition system. T he part contains a high speed 12-bit  
ADC, on-chip reference, on-chip clock and four track/hold am-  
plifiers. T his 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. T his makes  
the AD7874 ideal for applications such as phased-array sonar  
and ac motor controllers where the relative phase information is  
important.

1. Simultaneous Sampling of Four Input Channels.  
Four input channels, each with its own track/hold amplifier,  
allow simultaneous sampling of input signals. T rack/hold ac-  
quisition time is 2 µs, and the conversion time per channel is  
8 µs, allowing 29 kHz sample rate for all four channels.  
T he aperture delay of the four track/hold amplifiers is small and  
specified with minimum and maximum limits. T his allows sev-  
eral AD7874s 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.  
2. T ight Aperture Delay Matching.  
T he aperture delay for each channel is small and the aperture  
delay matching between the four channels is less than 4 ns.  
Additionally, the aperture delay specification has upper and  
lower limits allowing multiple AD7874s to sample more than  
four channels.  
3. Fast Microprocessor Interface.  
In addition to the traditional dc accuracy specifications such as  
linearity, full-scale and offset errors, the AD7874 is also fully  
specified for dynamic performance parameters including distor-  
tion and signal-to-noise ratio.  
T he high speed digital interface of the AD7874 allows direct  
connection to all modern 16-bit microprocessors and digital  
signal processors.  
T he AD7874 is fabricated in Analog Devices’ Linear Compat-  
ible CMOS (LC2MOS) process, a mixed technology process  
that combines precision bipolar circuits with low-power CMOS  
logic. T he part is available in a 28-pin, 0.6" wide, plastic or her-  
metic dual-in-line package (DIP), in a 28-terminal leadless ce-  
ramic chip carrier (LCCC) and in a 28-pin SOIC.
