MAX-256-X-Optoelectronics
The MXA-256-X detector is a hybrid focal plane InGaAs PIN photodiode array with wavelength response ranging from 800 nm to 1700 nm. The array has 256 elements in a straight line orientation with a standard configuration of 0.5 mm in height. A buffered multiplexer provides individual CMOS amplifiers for each photodiode. Integrating amplifiers maintain zero volt bias on each InGaAs photodiode, minimizing dark current and low frequency noise, and allowing longer exposure times to increase sensitivity. A static transition register sequential scan circuit selects samples and maintains an integrated output voltage proportional to the input optical power. On-chip correlated double sampling removes integral shift and further suppresses low frequency noise. "The array is in a 28-pin dual-column line package. The assembly includes a single-stage thermoelectric cooler, bias resistors and silicon multiplexer bypass capacitors.
