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