5 / 20 page ![]() MP8830 5 Rev. 1.00 Parameter Test Conditions/Comments Units Max Typ Min Symbol Offset DAC Resolution N 6 Bits Differential Non-Linearity DNL –0.5 0.5 LSB Integral Non-Linearity INL 1 LSB VRB Range ZSR 152 158 164 mV This is measured as the voltage difference at the clamp pin of the selected channel when the offset DAC changed from 000 (hex) to 3F (hex) with the gain DAC at 1FF (hex). Refer to VRT and VRB EQNs in the theory of opera- tion section. Maximum Offset Change per Cycle2 MOC 100 % FSR After the specified maximum change in offset DAC setting, the ADC should output the same code 1 LSB for all of the following conver- sions assuming the analog input remains fixed, i.e. DC. Full Scale Settling Time2 ts-od 200 ns For a 00 (hex) to 3F (hex) change of offset DAC code. Black Level Clamp Switch On Resistance RON 100 150 Ω Effective RIN at clamp pin. Input Leakage ILCLP 25 nA Offset DAC at 00 (hex) (worst case condition). Clamp Switching Charge Injection2 QCLP 50 pC Offset DAC at 00 (hex) (worst case condition). Voltage at Clamp Pin VCLP 170 180 190 mV Offset by 4 LSB from bottom tap of ADC lad- der. Gain = 000 (H). Offset DAC = 00. Reference Voltage Requirements (See Theory of Operation) Reference Voltage VREF 0.93 1 1.07 V All linearity specifications assume the refer- ence voltage = AVDD X ( 0.2 ). 0.5 1.15 V Functional.
