CS5373A
DS703F2 11
DAC AC DIFFERENTIAL MODES 1, 2, 3 (CONT.)
Notes: 25. Specification measured using CS3301A amplifier at corresponding gain with the modulator measuring
a 400 Hz bandwidth. Amplified noise dominates for x16, x32, x64 amplifier gains.
26. Buffered outputs (BUF
±) include 1/f noise not present on the precision outputs (OUT±).
27. Specification measured using CS3301A amplifier at corresponding gain using the modulator measuring
a 400 Hz bandwidth. Amplified noise in the harmonic bins dominates THD measurements for x16, x32,
x64 amplifier gains.
