97 / 105 page  MB91F155A/MB91155/MB91154 97 6. A/D Converter Electrical Characteristics (VCC = 3.15 V to 3.6 V, VSS = AVSS = 0 V, TA = 0 °C to +70 °C) Notes : • The smaller the |AVRH| is, the greater the error is in general. • The external circuit output impedance of analog input should be used in compliance with the following requirements : External circuit output impedance ≤ 2 (kΩ) If the output impedance of the external circuit is too high, an analog voltage sampling duration shortage might occur. (Sampling duration = 1.4 µs : @33 MHz) Parameter Sym- bol Pin name Condition Value Unit Re- marks Min Typ Max Resolution 10 Bit Conversion time 5.1 µs Total error AVCC = 3.3 V, AVRH = 3.3 V ±4.0 LSB Linearity error ±3.5 LSB Differential linearity error ±2.0 LSB Zero transition error VOT AN0 to AN7 AVCC = 3.3 V, AVRH = 3.3 V AVSS − 1.5 AVSS + 0.5 AVSS + 2.5 LSB Full-scale transition error VFST AN0 to AN7 AVRH − 5.5 AVRH − 1.5 AVRH + 0.5 LSB Analog input current IAIN AN0 to AN7 0.1 10 µA Analog input voltage VAIN AN0 to AN7 AVSS AVRH V Reference voltage AVRH AVRH AVCC V Supply current Conversion in operation IA AVCC AVCC = 3.3 V 3.0 5.0 mA Conversion stopped IAH 5.0 µA Reference voltage supply current Conversion in operation IR AVRH AVCC = 3.3 V, AVRH = 3.3 V 2.0 3.0 mA Conversion stopped IRH 10 µA Interchannel variation AN0 to AN7 4LSB |
