Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: All voltage values are with respect to ground with DGND, AGND1

and AGND2 wired together (unless otherwise noted).

Note 3: When these pin voltages are taken below ground or above VANA =

VDIG = VDD, they will be clamped by internal diodes. This product can

handle input currents of greater than 100mA below ground or above VDD

without latch-up.

Note 4: When these pin voltages are taken below ground, they will be

clamped by internal diodes. This product can handle input currents of

90mA below ground without latchup. These pins are not clamped to VDD.

Note 5: VDD = 5V, fSAMPLE = 250kHz, tr = tf = 5ns unless otherwise

specified.

Note 6: Linearity, offset and full-scale specifications apply for a VIN input

with respect to ground.

Note 7: Integral nonlinearity is defined as the deviation of a code from a

straight line passing through the actual end points of the transfer curve.

The deviation is measured from the center of the quantization band.

Note 8: Bipolar offset is the offset voltage measured from – 0.5 LSB when

the output code flickers between 0000 0000 0000 0000 and 1111 1111

1111 1111.

Note 9: Guaranteed by design, not subject to test.

Note 10: Recommended operating conditions.

Note 11: With CS low the falling R/C edge starts a conversion. If R/C

returns high at a critical point during the conversion, it can create errors.

For best results, ensure that R/C returns high within 1µs after the start of

the conversion.

Note 12: As measured with fixed resistors shown in Figure 4. Adjustable to

zero with external potentiometer.

Note 13: Full-scale error is the worst-case of –FS or +FS untrimmed

deviation from ideal first and last code transitions, divided by the transition

voltage (not divided by the full-scale range) and includes the effect of

offset error.

Note 14: All specifications in dB are referred to a full-scale ±10V input.

Note 15: Full-power bandwidth is defined as full-scale input frequency at

which a signal-to-(noise + distortion) degrades to 60dB or 10 bits of

accuracy.

Note 16: Recovers to specified performance after (2 • FS) input

overvoltage.
