Notes: 15. Specification measured using CS3301A amplifier at corresponding gain with the CS5371A / CS5372A
modulator measuring a 430 Hz bandwidth. Amplified noise dominates for x16, x32, x64 amplifier gains.
16. Buffered outputs (BUF±) include 1/f noise not present on the precision outputs (OUT±).
17. Tested with a 31.25 Hz sine wave at -1 dB amplitude.
18. Specification measured using CS3301A amplifier at corresponding gain using the CS5371A / CS5372A
modulator measuring a 430 Hz bandwidth. Amplified noise in the harmonic bins dominates THD
measurements for x16, x32, x64 amplifier gains.
