40 / 65 page ![]() Table 28. Comparator with 8-bit DAC electrical specifications (continued) Symbol Description Min. Typ. Max. Unit Analog comparator hysteresis, Hyst2, Low-speed mode -40 - 125 ℃ — 23 80 VHYST3 Analog comparator hysteresis, Hyst3, High-speed mode mV -40 - 125 ℃ — 46 200 Analog comparator hysteresis, Hyst3, Low-speed mode -40 - 125 ℃ — 32 120 IDAC8b 8-bit DAC current adder (enabled) 3.3V Reference Voltage — 6 9 μA 5V Reference Voltage — 10 16 μA INL5 8-bit DAC integral non-linearity –0.75 — 0.75 LSB6 DNL 8-bit DAC differential non-linearity –0.5 — 0.5 LSB6 tDDAC Initialization and switching settling time — — 30 μs 1. Difference at input > 200mV 2. Applied ± (100 mV + VHYST0/1/2/3+ max. of VAIO) around switch point. 3. Applied ± (30 mV + 2 × VHYST0/1/2/3+ max. of VAIO) around switch point. 4. Applied ± (100 mV + VHYST0/1/2/3). 5. Calculation method used: Linear Regression Least Square Method 6. 1 LSB = Vreference/256 NOTE For comparator IN signals adjacent to VDD/VSS or XTAL/ EXTAL or switching pins cross coupling may happen and hence hysteresis settings can be used to obtain the desired comparator performance. Additionally, an external capacitor (1nF) should be used to filter noise on input signal. Also, source drive should not be weak (Signal with < 50 K pull up/down is recommended).
