Senseeker Engineering has developed a digital readout integrated circuit (DROIC) with low-noise performance fo  low-light applications such as short-wave Infrared (SWIR) and low-current detector technologies such as quantum dots-based detectors.

The Senseeker Neon RD0033 has triple-gain modes and a 10 μm pitch pixel with a capacitive transimpedance amplifier (CTIA) front-end circuit in high operating temperatures.

The Neon RD0033 has a 640 x 512 format and a frame rate of 700 fps with programmable well capacities of 22 ke-, 160 ke- and 1.1 Me- with a global shutter chip with both internal synchronous integration control modes and external asynchronous integration control and can be used for range-gating applications.

The very low read noise is 15 electrons at room temperature in high-gain and the contains both on-chip and off-chip correlated double sampling modes operates in both integrate-then-read and integrate-while-read modes.

The RD0033 also features typical Senseeker product modes such as sample-up-the-ramp, on-chip temperature monitoring and programmable multiple high-speed windows to observe and track targets at thousands of frames per second.

“The low-noise and high-sensitivity of Senseeker’s Neon family of digital readouts enables extremely high-performance infrared imaging in the next generation of SWIR cameras,” said Dr. Martin H. Ettenberg, President and CEO at Princeton Infrared Technologies. “This new level of performance will allow Princeton Infrared Technologies to continue to offer high performance SWIR cameras and imagers across the Industrial, Scientific and defence markets.”

“The Neon RD0033 CTIA DROIC is the first in a family of Senseeker chips that provides an attractive, flexible and low-noise solution for a wide range of applications,” said Kenton Veeder, President of Senseeker. “We have worked hard to ensure customers will be happy with the ease of use and high- end performance this off-the-shelf DROIC will bring to their applications.”

The Neon RD0033 is in production now and is supported by an electronics kit and a thermoelectric cooler sensor test unit that, together, enable testing and evaluation of Neon-based focal plane arrays.
