NOTES

1“Gain Tempco” is for converter using internal reference; “Temperature

Coefficient” is for bandgap reference only.

2Output propagation delay (t

PD) is measured from the 50% point of the falling

edge of the encode command to the min/max voltage levels of the digital

outputs with 10 pF maximum loads.

3RMS signal to rms noise with analog input signal 1 dB below full scale at

specified frequency.

4ENCODE = 32 MSPS.

53rd order intermodulation measured with analog input frequencies of 2.3 MHz

and 2.4 MHz at 7 dB below full scale.

6For rated performance at 40 MSPS, duty cycle of encode command should be

50%

±10%.

7Measured as the ratio of the change in offset voltage for a 5% change in +V

or –VS.

Specifications subject to change without notice.

EXPLANATION OF TEST LEVELS

Test Level

– 100% Production Tested.

II – 100% production tested at +25

°C, and sample tested at

specified temperatures. AC testing done on sample basis.

III – Sample Tested Only.

IV – Parameter is guaranteed by design and characterization

testing.

V – Parameter is a typical value only.

VI – All devices are 100% production tested at +25

°C. 100%

production tested at temperature extremes for military

temperature devices; guaranteed by design and character-

ization testing for industrial devices.

NOTES

1Absolute maximum ratings are limiting values to be applied individually, and

beyond which the serviceability of the circuit may be impaired. Functional

operability is not necessarily implied. Exposure to absolute maximum rating

conditions for an extended period of time may affect device reliability.

2Typical thermal impedances (parts soldered to board):

N Package (Plastic DIP):

JA = 42°C/W; θJC = 10°C/W.

R Package (SOIC):

JA = 47°C/W; θJC = 10°C/W.
