• Manufacturer Part Number: PCM78
• Description: 16-Bit Audio ANALOG-TO-DIGITAL CONVERTER
• Manufacturer: Burr-Brown Corporation

SPECIFICATIONS
ELECTRICAL
At T
NOTES: (1) When convert command is high, converter is in a halt/reset mode. Actual conversion begins on negative edge. See detailed text on timing for convert
command description when using external clock. (2) Ratio of Noise rms/Signal rms. (3) f = input frequency; f
combination); BW = bandwidth of output (based on FFT or actual analog reconstruction using a 20kHz low-pass filter). (4) Referred to input signal level. (5) Ratio
of Distortion rms/Signal rms. (6) Ratio of Distortion rms + Noise rms/Signal rms. (7) FSR: Full-Scale Range = 6Vp-p. (8) Typically no missing Codes at 14-bit
resolution.
