Typ. Max. ADC LINE_IN Input Voltage Range from IOB[7:0] VINL (Note 1) VSS-0.3 - V33_ADC+0.3 V ADC Microphone Input Voltage Range VINM VSS-0.3 - V33_ADC+0.3 V Resolution of ADC RESO - - 12 bits Signal-to-Noise Plus Distortion of ADC from Line in SINAD (Note 3) - 50 - dB Effective Number of Bit ENOB (Note 4) 7.0 8.0 - bits Integral Non-Linearity of ADC INL - ±5.0 - LSB (Note 2) Differential Non-Linearity of ADC DNL (Note 6) - ±1.0 - LSB AD Conversion Rate FCONV - - FCPU/256 Hz Microphone Amplifier Gain A MIC - - 42(Note 5) dB Note1: Internal protection diodes clamp the analog input to V33_ADC and VSS. These diodes allow the analog input to swing from (VSS-0.3V) to (V33_ADC+0.3V) without causing damage to the devices. Note2: LSB means Least Significant Bit. With VINL = 2.6V, 1LSB = 2.6V/2^12 = 0.635mV. Note3: The SINAD testing condition at VINLp-p = 0.8*V33_ADC, FCONV = Fcpu/512 = 49MHz/256 = 192KHz, Fin=1.0KHz Sine waves at V33_ADC = 3.0V from the IOB [7:0] input. Note4: ENOB = (SINAD-1.76)/6.02. Note5: The microphone amplifier maximum gain = 15 * (60K/(1.5K+REXT) V/V. The REXT is external resistor between OPI and MICOUT. The gain is 132V/V (=42dB) when REXT is 5.1K. |
