Note1: Internal protection diodes clamp the analog input to AVDD and VSS. These diodes allow the analog input to swing from (VSS-0.3V) to (AVDD+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.

[7:0] input.

Note4: ENOB = (SINAD-1.76)/6.02.

Note5: The ADC of GPCE048A can guarantee 12 bits no missing code.

Note6: 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.
