Electrical Characteristics
Table A-21. ADC Conversion Performance 5V range (Junction Temperature From –40°C To +150°C)
S12GNA16, S12GNA32, S12GAS48, S12GA64, S12GA96, S12GA128, S12GA192 and S12GA240
Supply voltage 4.5V < V_DDA < 5.5 V, -40^oC < T_J < 150^oC, V_REF = V_RH - V_RL = V_DDA, f_ADCCLK = 8.0MHz
The values are tested to be valid with no port AD output drivers switching simultaneous with conversions.

1 _{The 8-bit and 10-bit mode operation is structurally tested in production test. Absolute values are tested in 12-bit mode.}
2 _{These values include the quantization error which is inherently 1/2 count for any A/D converter.}
