TIMING CHARACTERISTICS (Note 5)
The l denotes specifications that apply over the full operating temperature
Note 7:
Integral nonlinearity is defined as the deviation of a code from a range. straight line passing through the actual endpoints of the transfer curve.
Note 1:
Absolute Maximum Ratings are those values beyond which the life The deviation is measured from the center of the quantization band. of a device may be impaired.
Note 8:
Typical RMS noise at the code transitions. See Figure 17 for
Note 2:
All voltage values are with respect to ground with DGND, OGND histogram. and AGND wired together unless otherwise noted.
Note 9:
Bipolar offset is the offset voltage measured from –0.5LSB when
Note 3:
When these pin voltages are taken below V the output code flickers between 0000 0000 0000 0000 and 1111 1111 SS or above VDD, they will be clamped by internal diodes. This product can handle input currents 1111 1111. greater than 100mA below VSS or above VDD without latchup.
Note 10:
Signal-to-Noise Ratio (SNR) is measured at 5kHz and distortion
Note 4:
When these pin voltages are taken below V is measured at 100kHz. These results are used to calculate Signal-to-Nosie SS, they will be clamped by internal diodes. This product can handle input currents greater than Plus Distortion (SINAD). 100mA below VSS without latchup. These pins are not clamped to VDD.
Note 11:
Guaranteed by design, not subject to test.
Note 5:
VDD = 5V, VSS = –5V, fSMPL = 333kHz, and tr = tf = 5ns unless
Note 12:
Recommended operating conditions. otherwise specified.
Note 13:
The falling CONVST edge starts a conversion. If CONVST returns
Note 6:
Linearity, offset and full-scale specification apply for a single- high at a critical point during the conversion it can create small errors. For ended A + – IN input with AIN grounded. best performance ensure that CONVST returns high either within 250ns after conversion start or after BUSY rises.
