Characteristic Sym. Min. Typ. Max. Units Conditions High-Level Input Voltage VIH 0.7 DVDD — — V Schmitt-Triggered Low-Level Input Voltage VIL —— 0.3 DVDD V Schmitt-Triggered Input Leakage Current ILI —— ±1 µA CS = DVDD, VIN = DGND to DVDD Output Leakage Current ILO —— ±1 µA CS = DVDD, VOUT = DGND or DVDD Hysteresis Of Schmitt-Trigger Inputs VHYS —500 — mV DVDD = 3.3V only, Note 2 Low-Level Output Voltage VOL —— 0.2 DVDD VIOL = +1.7 mA Note 1: This parameter is periodically sampled and not 100% tested. 2: This parameter is established by characterization and not production tested. TABLE 1-1: ANALOG SPECIFICATIONS (CONTINUED) Electrical Specifications: Unless otherwise indicated, all parameters apply at AVDD = DVDD = 3V, MCLK = 4 MHz; PRE<1:0> = 00 ; OSR = 256; GAIN = 1; VREFEXT = 0, CLKEXT = 1, DITHER<1:0> = 11; BOOST<1:0> = 10, VCM =0V; TA = -40°C to +125°C; VIN = -0.5 dBFS @ 50/60 Hz on all channels. Characteristic Sym. Min. Typ. Max. Units Conditions Note 1: Dynamic Performance specified at -0.5 dB below the maximum differential input value, VIN =1.2 VPP = 424 mVRMS @ 50/60 Hz, VREF = 1.2V. See Section 4.0 “Terminology And Formulas” for definition. This parameter is established by characterization and not 100% tested. 2: For these operating currents, the following configuration bit settings apply: SHUTDOWN<3:0> = 0000 , RESET<3:0> = 0000 , VREFEXT = 0, CLKEXT = 0. 3: For these operating currents, the following configuration bit settings apply: SHUTDOWN<3:0> = 1111 , VREFEXT = 1, CLKEXT = 1. 4: Measured on one channel versus all others channels. The average of crosstalk performance over all channels (see Figure 2-32 for individual channel performance). 5: Applies to all gains. Offset and gain errors depend on PGA gain setting, see typical performance curves for typical performance. 6: Outside of this range, ADC accuracy is not specified. An extended input range of +/-2V can be applied continuously to the part with no damage. 7: For proper operation and for optimizing ADC accuracy, AMCLK should be limited to the maximum frequency defined in Table 5-2, as a function of the BOOST and PGA setting chosen. MCLK can take larger values as long as the prescaler settings (PRE<1:0>) limit AMCLK = MCLK/PRESCALE in the defined range in Table 5-2. 8: This parameter is established by characterization and not 100% tested. |
