Fast preamplifier electronics for Hamamatsu
N-MOS Linear Image Sensors
(photodiode arrays, PDA) types S3901 to S3904
Pixel frequency up to 1 MPixel per second
For 16 bit readout
Sensor chip socket for direct insertion on PCB
Device input: sensor chip
Device output:
tec5 16 bit Front End Electronics with
sensor interface ‚Sensor_U3’ (FEE-1M /NMOS-1)
PCB dimensions: 73 mm x 37 mm
Low-speed version /Dxx available, reduced
readout noise for 100 kPixel per second readout

General
The preamplifier electronics DZA-S3901-4 1M serves
as an interfacing component between the Hamamatsu
N-MOS Linear Image Sensors of series S3901 to
S3904 and the Front End Electronics board of a tec5
operating electronics. Typically the PDA is plugged
directly into the DIL-22 socket mounted to the soldering
side of the PCB.
The electronics is designed for a readout rate of up to
1 MPixel per second. Using the product version /Dxx at
a clock rate of 100 kPixel per second results in lower
detection noise, but longer minimum integration time
and slower achievable measurement rate. Both versions are supported by corresponding versions of the
tec5 FEE-1M /NMOS-1 or FEE-1M /NMOS-D1.
The interface to the Front End Electronics complies to
the tec5 specification ‚Sensor_U3’ (MICS-14, MICS-4
and SMB socket with pin contact, video signal ‚differential’).

Description of Operation
Based on the CLK and START input signals the preamplifier board generates all signals required to read out

the sensor chip. The analog signal from the sensor
array is preamplified, integrated, and forwarded differentially for further processing (video signal).
The onboard gated signal integration is controlled by
the input signal I_RES. I_RES must be driven high for
integration of the pulse at each pixel and low to reset
the integrator.
The attached scan control electronics has to provide the
clock signals START and CLK according to the timing
specification of the PDA and to control the integration
by the signal I_RES. At the end of the readout sequence the PDA produces an EndOfScan pulse.
The video output signal is differential. Dark condition
results in a level of 0V on both outputs and full light
generates +4V at the positive and –4V at the inverted
output.
