(TYP.: TA = 25C, VIN = VIN = 0 V, VDD1 = VDD2 = 5 V, MIN., MAX.: refer to RECOMMENDED OPERATING CONDITIONS, unless otherwise specified) Parameter Symbol Conditions MIN. TYP. MAX. Unit Signal to Noise Ratio *8 SNR VIN = 35 Hz, 400 mVpk-pk 80 85 dB (141 mVr.m.s.) sine wave Signal to Noise and Distortion SNDR 69 79 dB Ratio *9 Effective Number of Bit *10 ENOB 13.8 bits *8 Signal to Noise Ratio (SNR) is the ratio of the AC signal power to the noise power that excludes harmonic signals and DC. SNR is defined as follows, SNR (dB) = 10 log(PS/PN) PS: Signal power (fundamental) PN: Noise power (excluding harmonic signals and DC) *9 Signal to Noise and Distortion ratio (SNDR) is the ratio of the AC signal power (fundamental) to the noise power plus distortion power. SNDR is defined as follows, SNDR (dB) = 10 log(PS/(PN PH2 PH3 ... PH5)) PS: Signal power (fundamental) PN: Noise power (excluding harmonic signals and DC) PH2, PH3 ... PH5: Second through fifth harmonics power *10 Effective Number of Bit (ENOB) is the effective resolution of ADC that is considered the noise. ENOB is defined as fol ows, ENOB (bits) = (SNR1.76)/6.02 R08DS0174EJ0100 Rev.1.00 Page 7 of 19 Mar 23, 2020
