Notes: 1. CS4362-KQ parts are tested at 25 °C.
2. One-half LSB of triangular PDF dither is added to data.
3. Performance limited by 16-bit quantization noise.
4. CS4362-BQ parts are tested at the extremes of the specified temperature range and Min/Max
performance numbers are guaranteed across the specified temperature range, T_A. Typical numbers are
taken at 25 °C.
