ELECTRICAL CHARACTERISTICS

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 small

errors. For best results ensure that R/C returns high within 3µs 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.
