These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. recommended operating conditions MIN NOM MAX UNIT Supply voltage VDD VDD = 5 V 4.5 5 5.5 V Supply voltage, VDD VDD = 3 V 2.7 3 3.3 V High-level digital input voltage, VIH VDD = 2.7 V to 5.5 V 2 V Low-level digital input voltage, VIL VDD = 2.7 V to 5.5 V 0.8 V Reference voltage, Vref to REFIN terminal VDD = 5 V (see Note 1) AGND 2.048 VDD –1.5 V Reference voltage, Vref to REFIN terminal VDD = 3 V (see Note 1) AGND 1.024 VDD – 1.5 V Load resistance, RL 2 10 k Ω Load capacitance, CL 100 pF Clock frequency, fCLK 20 MHz Operating free air temperature TA TLV5623C 0 70 °C Operating free-air temperature, TA TLV5623I –40 85 °C NOTE 1: Due to the x2 output buffer, a reference input voltage ≥ VDD/2 causes clipping of the transfer function. electrical characteristics over recommended operating free-air temperature range (unless otherwise noted) power supply PARAMETER TEST CONDITIONS MIN TYP MAX UNIT VDD = 5 V, VREF = 2.048 V, No load, Fast 0.9 1.35 mA IDD Power supply current All inputs = AGND or VDD, DAC latch = 0x800 Slow 0.4 0.6 mA IDD Power supply current VDD = 3 V, VREF = 1.024 V No load, Fast 0.7 1.1 mA All inputs = AGND or VDD, DAC latch = 0x800 Slow 0.3 0.45 mA Power down supply current (see Figure 12) 1 µA PSRR Power supply rejection ratio Zero scale See Note 2 –68 dB PSRR Power supply rejection ratio Full scale See Note 3 –68 dB Power on threshold voltage, POR 2 V NOTES: 2. Power supply rejection ratio at zero scale is measured by varying VDD and is given by: PSRR = 20 log [(EZS(VDDmax) – EZS(VDDmin))/VDDmax] 3. Power supply rejection ratio at full scale is measured by varying VDD and is given by: PSRR = 20 log [(EG(VDDmax) – EG(VDDmin))/VDDmax] |
