ADC characteristics
|
Number of channels
| 2 channels. Available the following order options:
2 voltage channels (U+U
option),
1 low-current, 1 volatage channel (I+U
option - standard),
2 low-current channels (I+I
option)
|
Type / ADC resolution
| Sigma-delta ADC AD 7710 / 24 bit
|
Effective resolution |
22-24 bits (at sampling rate of 10 Hz)
Note 1: Low-current channel utilise automatic range switching,
so the total dynamic range 107
would be:
log2(107) = true 24 bit
Note 2: Voltage channel also use the internal gain switching
to obtain maximal resolution performance.
log2(6V / 0.3mkV) = true 24 bit
