E | Page 5 of 40 Parameter Y Version1 Unit Test Conditions/Comments Min Typ Max RECEIVE STAGE Input Leakage Current 1 nA To VIN pin Input Capacitance6 0.01 pF Pin capacitance between VIN and GND Feedback Capacitance (CFB) 3 pF Feedback capacitance around current- to-voltage amplifier; appears in parallel with feedback resistor ANALOG-TO-DIGITAL CONVERTER6 Resolution 12 Bits Sampling Rate 1 MSPS ADC throughput rate TEMPERATURE SENSOR Accuracy ±2.0 °C −40°C to +125°C temperature range Resolution 0.03 °C Temperature Conversion Time 800 μs Conversion time of single temperature measurement LOGIC INPUTS Input High Voltage (VIH) 0.7 × VDD Input Low Voltage (VIL) 0.3 × VDD Input Current7 1 µA TA = 25°C Input Capacitance 7 pF TA = 25°C POWER REQUIREMENTS VDD 2.7 5.5 V IDD (Normal Mode ) 10 15 mA VDD = 3.3 V 17 25 mA VDD = 5.5 V IDD (Standby Mode) 11 mA VDD = 3.3 V; see the Control Register (Register Address 0X80, Register Address 0X81) section 16 mA VDD = 5.5 V IDD (Power-Down Mode) 0.7 5 µA VDD = 3.3 V 1 8 µA VDD = 5.5 V 1 Temperature range for Y version = −40°C to +125°C, typical at 25°C. 2 The lower limit of the output excitation frequency can be lowered by scaling the clock supplied to the AD5933. 3 Refer to Figure 14, Figure 15, and Figure 16 for the internal oscillator frequency distribution with temperature. 4 The peak-to-peak value of the ac output excitation voltage scales with supply voltage according to the following formula: Output Excitation Voltage (V p-p) = [2/3.3] × VDD where VDD is the supply voltage. 5 The dc bias value of the output excitation voltage scales with supply voltage according to the following formula: Output Excitation Bias Voltage (V) = [2/3.3] × VDD where VDD is the supply voltage. 6 Guaranteed by design or characterization, not production tested. Input capacitance at the VOUT pin is equal to pin capacitance divided by open-loop gain of current- to-voltage amplifier. 7 The accumulation of the currents into Pin 8, Pin 15, and Pin 16. |
