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. NOTE 1: VDD1 is the voltage measured at DGTL VDD1 with respect to DGND1. VDD2 is the voltage measured at DGTL VDD2 with respect to the DGND2. VDD3 is the voltage measured at ANLG VDD with respect to AGND. For these specifications, all ground terminals are tied together (and represent 0 V). When VDD1, VDD2, and VDD3 are equal, they are referred to simply as VDD. recommended operating conditions MIN NOM MAX UNIT Supply voltage, VDD1, VDD2, VDD3 4.75 5 5.5 V Positive reference voltage, VREF+ (see Note 2) VDD3 V Negative reference voltage, VREF− (see Note 2) 0 V Differential reference voltage, VREF+ − VREF − (see Note 2) VDD3 V Analog input voltage range 0 VDD3 V High-level control input voltage, VIH 2 V Low-level control input voltage, VIL 0.8 V Input clock frequency, f(CLKIN) 0.5 7.8 MHz Setup time, CS low before WR or RD goes low, tsu(CS) 0 ns Hold time, CS low after WR or RD goes high, th(CS) 0 ns WR or RD pulse duration, tw(WR) 50 ns Input clock low pulse duration, tw(L−CLKIN) 40% of period 80% of period Operating free-air temperature, TA TLC155xI −40 85 °C Operating free-air temperature, TA TLC1550M −55 125 °C NOTE 2: Analog input voltages greater than that applied to REF+ convert to all 1s (1111111111), while input voltages less than that applied to REF − convert to all 0s (0000000000). The total unadjusted error may increase as this differential voltage falls below 4.75 V. |
