SPCE061A Sunplus Technology Co., Ltd., SPCE061A Datasheet - Page 14

• Manufacturer Part Number: SPCE061A
• Description: 16-bit sound controller with 32k x 16 flash memory
• Manufacturer: Sunplus Technology Co., Ltd.

6.6. ADC Characteristics (VDD = 3.3V, T
Note1: Internal protection diodes clamp the analog input to VDD and VSS. These diodes allow the analog input to swing from (VSS-0.3V) to (VDD+0.3V)
Note2: The ADC performance is limited by the system noise level and therefore, the SPCE061A only guarantees to the 8-bit accuracy when VEXTREF is 2.0V.
Note3: The LSB means Least Significant Bit. VINL = 2.0V, 1LSB = 2.0V/2^10 = 1.953mV.
Note4: The SINAD testing condition at VINLp-p = 0.8*VDD, F
Note5: ENOB = (SINAD-1.76)/6.02.
Note6: The ADC of SPCE061A guarantees no data missed during conversion.
Note7: 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
