LZ2325A/LZ2326AR
LZ2325A/
LZ2326AR
Dual-power-supply (5 V/12 V) Operation
1/3-type CCD Area Sensors with 320 k Pixels
DESCRIPTION
The LZ2325A/LZ2326AR are 1/3-type (6.0 mm)
solid-state image sensors that consist of PN photo-
diodes and CCDs (charge-coupled devices) driven
by dual-power-supply. With approximately 320 000
pixels (542 horizontal x 582 vertical), the sensor
provides a stable high-resolution color (LZ2325A)/
B/W (LZ2326AR) normal or mirror image.
FEATURES
• Number of effective pixels : 512 (H) x 582 (V)
• Number of optical black pixels
– Horizontal : 2 front and 28 rear
• Pixel pitch : 9.6 µm (H) x 6.3 µm (V)
• Mg, G, Cy, and Ye complementary color filters
(For LZ2325A)
• Low fixed-pattern noise and lag
• No burn-in and no image distortion
• Blooming suppression structure
• Built-in output amplifier
• Built-in pulse mix circuit
• Built-in overflow drain voltage circuit and reset
gate voltage circuit
• Variable electronic shutter (1/50 to 1/10 000 s)
• Normal or mirror image output available from
common output pin
• Compatible with PAL standard (LZ2325A)/
CCIR standard (LZ2326AR)
• Package :
16-pin shrink-pitch WDIP [Ceramic]
(WDIP016-N-0500C)
Row space : 12.70 mm

PRECAUTIONS
• The exit pupil position of lens should be more
than 25 mm (LZ2325A)/20 mm (LZ2326AR) from
the top surface of the CCD.
• Refer to "PRECAUTIONS FOR CCD AREA
SENSORS" for details.

NOTES :
• Within the recommended operating conditions of VOD,
VOFD of the internal output satisfies with ABL larger than
1 000 times exposure of the standard exposure conditions,
and VSAT larger than 550 mV.
1. TA = +60 ˚C
2. The average output voltage under uniform illumination.
The standard exposure conditions are defined as when
Vo is 150 mV.
3. The image area is divided into 10 x 10 segments under
the standard exposure conditions. Each segment's
voltage is the average output voltage of all pixels within
the segment. PRNU is defined by (Vmax – Vmin)/Vo,
where Vmax and Vmin are the maximum and minimum
values of each segment's voltage respectively.
4. The image area is divided into 10 x 10 segments. Each
segment's voltage is the average output voltage of all
pixels within the segment. VSAT is the minimum
segment's voltage under 10 times exposure of the
standard exposure conditions.
5. The average output voltage under non-exposure
conditions.
6. The image area is divided into 10 x 10 segments under
non-exposure conditions. DSNU is defined by (Vdmax –
Vdmin), where Vdmax and Vdmin are the maximum and
minimum values of each segment's voltage respectively.
7. The average output voltage when a 1000 lux light
source with a 90% reflector is imaged by a lens of F4,
f50 mm.
8. The sensor is exposed only in the central area of V/10
square with a lens at F4, where V is the vertical image
size. SMR is defined by the ratio of the output voltage
detected during the vertical blanking period to the
maximum output voltage in the V/10 square.
9. The sensor is exposed at the exposure level
corresponding to the standard conditions. AI is defined
by the ratio of the output voltage measured at the 1st
field during the non-exposure period to the standard
output voltage.
10. The sensor is exposed only in the central area of V/10
square, where V is the vertical image size. ABL is
defined by the ratio of the exposure at the standard
conditions to the exposure at a point where blooming is
observed.
