6. Common mode signals pass unchanged through the differential amplifier architecture and are rejected
by the CS5371A / 72A / 73A modulator CMRR.
7. Absolute gain accuracy tests the matching of x1 gain across multiple CS3301A devices.
8. Relative gain accuracy tests the tracking of x2, x4, x8, x16, x32, x64 gain relative to x1 gain on a single
CS3301A device.
9. Specification is for the parameter over the specified temperature range and is for the CS3301A device
only. It does not include the effects of external components.
10. Offset voltage is tested with the amplifier inputs connected to the internal 800 ? termination.
11. The absolute offset after calibration specification applies to the effective offset voltage of the CS3301A
output when used with the CS5371A / 72A / 73A modulator and CS5376A / 78 digital filter, and is
measured from the digitally calibrated output codes of the digital filter.
12. The CS3301A offset calibration is performed digitally with the CS5371A / 72A / 73A modulator and
CS5376A / 78 digital filter and includes the full scale signal range. Calibration offsets of greater than
± 5% of full scale will begin to subtract from system dynamic range.
