PERFORMANCE SPECIFICATIONS
Notes: 12. Dynamic Range defined as 20 log [(RMS full scale) / (RMS idle noise)] where idle noise is measured
with the amplifier input terminated. Dynamic Range is dominated by high-frequency quantization noise
at the 1/4 ms rate and amplifier noise at high gain.
13. Tested with a 31.25 Hz sine wave at 1 ms sampling rate and -1 dB amplitude.
