GENERAL DESCRIPTION
The functionally complete, easy-to-use ADS-CCD1201 is a
12-bit, 1.2MHz Sampling A/D Converter whose performance
and production testing have been optimized for use in
electronic imaging applications, particularly those employing
charge coupled devices (CCD’s) as their photodetectors. The
ADS-CCD1201 delivers the lowest noise (400µVrms) and the
best differential nonlinearity error (±0.35LSB max.) of any
commercially available 12-bit A/D in its speed class. It can
respond to full scale input steps (from empty to full well) with
less than a single count of error, and its input is immune to
overvoltages that may occur due to blooming.
Packaged in an industry-standard, 24-pin, ceramic DDIP, the
ADS-CCD1201 requires ±15V (or ±12V) and +5V supplies and
typically consumes 1.7 (1.4) Watts. The device is 100%
production tested for all critical performance parameters and is
fully specified over both the 0 to +70°C and –55 to +125°C
operating temperature ranges.
For those applications using correlated double sampling, the
ADS-CCD1201 can be supplied without its internal sample-

Footnotes:
➀ All power supplies must be on before applying a start convert pulse. All
supplies and the clock (START CONVERT) must be present during warmup
periods. The device must be continuously converting during this time. There is
a slight degradation in performance when using ±12V supplies.
➁ Contact DATEL for availability of other input voltage ranges.
➂ A 100ns wide start convert pulse is used for all production testing.

➄ This is the time required before the A/D output data is valid after

TECHNICAL NOTES
3. When operating the ADS-CCD1201 from ±12V supplies, do not
drive external circuitry with the REFERENCE OUTPUT (pin 21).
The reference’s accuracy and drift specifications may not be
met, and loading the circuit may cause accuracy errors within
the converter.
1. Obtaining fully specified performance from the ADS-CCD1201
requires careful attention to pc-card layout and power supply
decoupling. The device’s analog and digital ground systems are
connected to each other internally. For optimal performance, tie
all ground pins (14, 19, and 23) directly to a large analog
ground plane beneath the package.
4. A passive bandpass filter is used at the input of the A/D for all
production testing.
Bypass all power supplies, as well as the REFERENCE
OUTPUT (pin 21), to ground with 4.7µF tantalum capacitors in
parallel with 0.1µF ceramic capacitors. Locate the bypass
capacitors as close to the unit as possible. If the user-installed
offset and gain adjusting circuit shown in Figure 2 is used, also
locate it as close to the ADS-CCD1201 as possible.
5. Applying a start pulse while a conversion is in progress (EOC =
logic "1") initiates a new and inaccurate conversion cycle. Data
for the interrupted and subsequent conversions will be invalid.
Table 1. Zero and Gain Adjust
2. ADS-CCD1201 achieves its specified accuracies without
external calibration. If required, the device’s small initial offset
and gain errors can be reduced to zero using the input circuit of
Figure 2. When using this circuit, or any similar offset and gaincalibration hardware, make adjustments following warmup. To
avoid interaction, always adjust offset before gain.

ADS-CCD1201
For the ADS-CCD1201, offset adjusting is normally
accomplished at the point where all output bits are 0’s and the
LSB just changes from a 0 to a 1. This digital output transition
ideally occurs when the applied analog input is +1/2LSB
(+1.2207mV).
CALIBRATION PROCEDURE
(Refer to Figures 2 and 3)
Any offset and/or gain calibration procedures should not be
implemented until devices are fully warmed up. To avoid
interaction, offset must be adjusted before gain. The ranges of
adjustment for the circuit of Figure 2 are guaranteed to
compensate for the ADS-CCD1201’s initial accuracy errors and
may not be able to compensate for additional system errors.
Gain adjusting is accomplished when all bits are 1’s and the
LSB just changes from a 1 to a 0. This transition ideally occurs
when the analog input is at +full scale minus 1 1/2 LSB’s
(+9.99634V).

2. Adjust the gain potentiometer until all output bits are 1’s and
the LSB flickers between 1 and 0.
All fixed resistors in Figure 2 should be metal-film types, and
multi-turn potentiometers should have TCR’s of 100ppm/°C or
less to minimize drift with temperature. In many applications,
the CCD will require an offset-adjust (black balance) circuit
near its output and also a gain stage, presumably with adjust
capabilities, to match the output voltage of the CCD to the
input range of the AID. If one is performing a "system I/O
calibration" (from light in to digital out), these circuits can be
used to compensate for the relatively small initial offset and
gain errors of the A/D. This would eliminate the need for the
circuit shown in Figure 2.

All DATEL sampling A/D converters are fully characterized and
specified over operating temperature (case) ranges of 0 to
+70°C and – 55 to +125°C. All room-temperature (TA = +25°C)
production testing is performed without the use of heat sinks or
forced-air cooling. Thermal impedance figures for each device
are listed in their respective specification tables.
These devices do not normally require heat sinks, however,
standard precautionary design and layout procedures should
be used to ensure devices do not overheat. The ground and
power planes beneath the package, as well as all pcb signal
runs to and from the device, should be as heavy as possible to
help conduct heat away from the package. Electricallyinsulating, thermally-conductive "pads" may be installed
underneath the package. Devices should be soldered to boards
rather than "socketed," and of course, minimal air flow over the
surface can greatly help reduce the package temperature.

In more severe ambient conditions, the package/junction
temperature of a given device can be reduced dramatically
(typically 35%) by using one of DATEL’s HS Series heat sinks.
See Ordering Information for the assigned part number. See
page 1-183 of the DATEL Data Acquisition Components
Catalog for more information on the HS Series. Request DATEL
Application Note AN-8, "Heat Sinks for DIP Data Converters,"or
contact DATEL directly, for additional information.
A/D converters are calibrated by positioning their digital
outputs exactly on the transition point between two adjacent
digital output codes. This can be accomplished by connecting
LED’s to the digital outputs and adjusting until certain LED’s
"flicker" equally between on and off. Other approaches employ
digital comparators or microcontrollers to detect when the
outputs change from one code to the next.
