MAXIM MAX-256-X

Description
The MXA-256-X detector is a hybrid
focal plane Indium Gallium Arsenide
PIN photodiode array with wavelength
response ranging from 800 nm to 1700
Multiplexed InGaAs PIN
Photodiode Array

nm. The array has 256 elements

configured in a linear orientation with
standard pixel height of 0.5 mm. A
buffered multiplexer provides individual
CMOS amplifiers for each photodiode.
The integrating amplifier maintains zero
volt bias across each InGaAs
photodiode, minimizing dark current
and low frequency noise and allowing
for longer exposure times with
increased sensitivity. A static shift
register scanning circuit sequentially
selects sample-and-hold integrator
output voltages which are proportional
to input optical power. On-chip
Features
correlated double sampling removes
• 256 multiplexed elements
integrator offsets and further
• High resolution (50 micron pitch)
suppresses low frequency noise. The
• Exposure times 10 micro sec. - 10 sec.
array is available in a 28 pin dual-in-line
• Wide dynamic range (14-bit)
package. Included in the assembly are
• Correlated double sampling
a single-stage thermoelectric cooler,
• 800 - 1700 nm response
silicon multiplexer, bias resistor and
bypass capacitors.
