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, AVDD, DVDD 2.7 3.3 V Power supply ripple 0.002 Vpp Input clock frequency, f(CLK) 38.4 kHz Input clock duty cycle 45 50 55 % Voltage offset applied at DC OFFSET, VI(DC OFFSET) (see Notes 1 and 2) 0.25 VDD–0.25 V Analog input voltage, VI(pp) (See Notes 1 and 2) VDD = 3.1 V 0.25 VDD – 0.25 Vpp High-level control input voltage, VIH VDD = 2.7 V to 3.3 V 0.2 DVDD V Low-level control input voltage, VIL VDD = 2.7 V to 3.3 V 0.8 DVDD V Operating free-air temperature, TA –25 85 °C NOTES: 1. VI(OFFSET) =VQ – VI(DC OFFSET) where VQ is the dc quiescent voltage of the signal applied to the SIG terminal. NOTES: 2. V I(PEAK) + V DD 2 * 0.25 V 4.217 * V I(OFFSET) *80 mV The pass-band filter gain represents the maximum specified voltage gain in volts/volt of the filter. The maximum gain for the filter is 4.217 V/V (12.5 dB). The input voltage range from this equation defines the maximum allowable input signal at the SIG terminal with a given voltage, VI(DC OFFSET), applied at the DC OFFSET terminal and a quiescent dc input voltage, VQ, of the signal applied at the SIG terminal. When the input voltage is within this range, the peak and valley DACs do not over range. The 80 mV value is the tolerance on the voltage output at the MID terminal. |
