NOTES
1Maximum ratings are limiting values to be applied individually, and beyond which
the serviceability of the device may be impaired. Functional operation under any of
these conditions is not necessarily implied. Exposure to absolute maximum rating
conditions for extended periods of time may affect device reliability.
2Applied voltage must be current-limited to specified range.
3Forcing voltage must be limited to specified range.
4Current is specified as negative when flowing into the device.
5Output High; one pin to ground; one second duration.
6Typical thermal impedances (no air flow) are as follows:
Ceramic DIP: θJA = 49°C/W; θJC = 15°C/W LCC: θJA = 69°C/W; θJC = 21°C/W
JLCC: θJA = 59°C/W; θJC = 19°C/W
To calculate junction temperature (TJ), use power dissipation (PD) and thermal
impedance: TJ = PD (θJA) + TAMBIENT = PD (θJC) = + TCASE.
7Measured with VIN = 0 V and CONVERT low (sampling mode).
8Determined by beat frequency testing for no missing codes.
9VRT VRB under all circumstances.
10Outputs terminated with 40 pF and eight 10 pull-up resistors.
11Interval from 50% point of leading edge CONVERT pulse to change in output
data.
12For full-scale step input, 8-bit accuracy attained in specified time.
13Recovers to 8-bit accuracy in specified time after –3 V input overvoltage.
14Output time skew includes high-to-low and low-to-high transitions as well as
bit-to-bit time skew differences.
15Measured at 20 MHz encode rate with analog input 1 dB below full scale.
16Measured at 35 MHz encode rate with analog input 1 dB below full scale.
17RMS signal to rms noise.
18Peak signal to rms noise.
19DC to 8 MHz noise bandwidth with 1.248 MHz slot; four sigma loading;
20 MHz encode.
20Clock frequency = 4 × NTSC = 14.32 MHz. Measured with 40-IRE
modulated ramp.
Specifications subject to change without notice.
EXPLANATION OF TEST LEVELS
Test Level I – 100% production tested.
Test Level II – 100% production tested at +25°C and
sample tested at specific temperatures.
Test Level III – Sample tested only.
Test Level IV – Parameter is guaranteed by design and
characterization testing.
Test Level V – Parameter is a typical value only.
Test Level VI – All devices are 100% production tested at
+25°C. 100% production tested at tempera-
ture extremes for military temperature de-
vices; sample tested at temperature extremes
for commercial/industrial devices.
