Senseeker Engineering has announced the availability of Calcium RP0033advanced digital pixel readout IC (DPROIC) with > 120 dB dynamic range and frame rate up to 700 fps.

The 20 µm p-on-n pixel and 640 x 512 format are an industry standard that allows the Calcium RP0033 chip to be used with existing detector and optical technology. Customers can accelerate the development of advanced HDR infrared focal plane arrays (FPAs) by hybridizing available off-the-shelf detectors with the most advanced new commercial sensing on the market.

Digital pixel reading differentiates well capacity from noise level. This allows for both better sensitivity and greater borehole capacity at the same time. The Calcium RP0033 has dual gain modes with programmable good capacitance of over 40 Me- and 400 Me-, each with extremely low readout noise of 50 and 330 electrons respectively at 80 K. The chip is controlled via Senseeker’s popular SenSPI interface for easy communication and fast output. It can operate in both integrate-after-read and integrate-while-read modes and has programmable windows to monitor and track targets at thousands of frames per second.

Senseeker’s Calcium architecture can be assembled up to 4k x 4k array size. This allows the proven base design to be “electronically stitched” together in blocks of 512 x 512 rows and columns to rapidly develop an entire DPROIC family ranging from small to very large formats. Larger format Calcium DPROICs are already in the works with a 2k x 1k unit coming soon.

The Calcium RP0033 is in production now and is supported by an electronics evaluation kit also available from Senseeker.
