  A hard x-ray, high-speed, high dynamic range scientific x-ray imager is
described. The imager is based on the mixed-mode pixel array detector (MM-PAD)
readout chip coupled to a 750 micron thick cadmium telluride (CdTe) sensor. The
full imager is a 2 x 3 tiled array of MM-PAD sensor/readout chip hybrids. CdTe
improves detection for high energy x-rays as compared to silicon sensors,
enabling efficient x-ray imaging to extend to >100 keV. The detector is capable
of 1 kHz imaging and in-pixel circuitry has been designed to allow for well
depths of greater than 4 x 10^{6} 80 keV x-rays. A charge integrating front-end
allows for quantitative measurement of high flux x-ray images beyond the
capabilities of photon counting detectors. Detector performance is summarized
and experimental measurements are presented.
