10. Offset voltage is tested with the amplifier inputs connected to the internal 800Ω termination.
11. The absolute offset after calibration specification applies to the effective offset voltage of the CS3302A
12. The CS3302A offset calibration is performed digitally with the CS5371A / 72A / 73A modulator and
7. Absolute gain accuracy tests the matching of x1 gain across multiple CS3302A devices.
8. Relative gain accuracy tests the tracking of x1,x2, x4,x16,x32,x64 gain relative to x1 gain on a single
9. Specification is for the parameter over the specified temperature range and is for the CS3302A device

measured from the digitally calibrated output codes of the CS5376A / 78.
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.
