LTC1605
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 3
μ
s 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.
