295 / 382 page  DS13543 Rev 1 295/382 STM32U5Axxx Electrical characteristics 348 5.3.26 Operational amplifiers characteristics IDDA(COMP) Comparator consumption from VDDA High-speed mode, static - 48 90 µA High-speed mode, with 50 kHz, ±100 mV overdrive square signal -50- Medium mode, static - 3 6 Medium mode, with 50 kHz, ±100 mV overdrive square signal -3.75 - Ultra-low-power mode, static - 0.3 1 Ultra-low-power mode, with 50 kHz, ±100 mV overdrive square signal -0.65 1. Specified by design and not tested in production, unless otherwise specified. 2. The input capacitance is negligible compared to the I/O capacitance. 3. Refer to Table 36: Embedded internal voltage reference. 4. No VREFINT division, includes only buffer consumption. 5. VREFINT division, includes resistor bridge and buffer consumption. 6. Evaluated by characterization. Not tested in production. 7. Mostly I/O leakage when used in analog mode. Refer to Ilkg parameter in Table 86: I/O static characteristics. Table 109. COMP characteristics(1)(2) (continued) Symbol Parameter Conditions Min Typ Max Unit Table 110. OPAMP characteristics(1)(2) Symbol Parameter Conditions Min Typ Max Unit VDDA Analog supply voltage range for OPAMP ON -1.60 - 3.6 V CMIR Common mode input range -0 - VDDA VIOFFSET Input offset voltage TJ = 30 °C, no load on output, Normal mode -- ±3 mV TJ= 30 °C, no load on output, Low-power mode -- ±3 All voltages and temperature, Normal mode -- ±7 All voltages and temperature, Low-power mode -- ±11.5 ∆VIOFFSET Input offset voltage drift over temperature Normal mode - ±7 - μV/°C Low-power mode - ±15 - TRIMOFFSETP TRIMLPOFFSETP Offset trim step at low common input voltage (0.1 × VDDA) - - 1.05 1.25 mV TRIMOFFSETN TRIMLPOFFSETN Offset trim step at high common input voltage (0.9 × VDDA) - - 1.05 1.25 |
