8. PARAMETER DEFINITIONS

Dynamic Range

Full-scale (RMS) signal to broadband noise ratio. The broadband noise is measured over the specified

bandwidth with the input grounded. Expressed in decibels.

Total Harmonic Distortion + Noise

The ratio of the rms value of the signal to the rms sum of all other spectral components over the specified

bandwidth (typically 10 Hz to 20 kHz), including distortion components. Expressed in decibels.

Frequency Response

A measure of the amplitude response variation from 10 Hz to 20 kHz relative to the amplitude response at

1 kHz. Units in decibels.

Interchannel Isolation

A measure of crosstalk between channels. Measured for each channel at the device’s output with a full-

scale signal applied to one channel adjacent to the channel under test, and no signal applied to all other

channels. Units in decibels.

Gain Error

The deviation from the nominal full-scale analog output for a full-scale digital input.

Gain Drift

The change in gain value with temperature. Units in ppm/°C.
