7 / 150 page  LM98722 www.ti.com SNAS487B – SEPTEMBER 2009 – REVISED MARCH 2015 6.4 Thermal Information TSSOP THERMAL METRIC(1) UNIT 56 TERMINALS RθJA Junction-to-ambient thermal resistance <66 °C/W (1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953. 6.5 Electrical Characteristics The following specifications apply for VA = VD = VC = 3.3 V, CL = 10 pF, and fINCLK = 15 MHz unless otherwise specified. All other limits TA = 25°C. PARAMETER TEST CONDITIONS MIN(1) TYP(2) MAX(1)(3) UNIT CMOS DIGITAL INPUT DC SPECIFICATIONS (RESETb, SH_R, SCLK, SENb) VIH Logical “1” Input Voltage 2.0 V VIL Logical “0” Input Voltage 0.8 V VIHYST Logic Input Hysteresis 0.6 VIH = VD: RESET, SEN 100 nA IIH Logical “1” Input Current SH_R, SCLK, SDI, CAL 65 μA CE 30 VIL = DGND RESET, SEN, -65 μA IIL Logical “0” Input Current SH_R, SCLK, SDI, CAL -100 nA CE -30 μA CMOS DIGITAL OUTPUT DC SPECIFICATIONS (SH1 to SH5, RS, CP, PHIA, PHIB, PHIC) VOH Logical “1” Output Voltage IOUT = -0.5 mA 3.0 V VOL Logical “0” Output Voltage IOUT = 1.6 mA 0.21 V VOUT = DGND 18 IOS Output Short Circuit Current mA VOUT= VD -25 VOUT = DGND 20 CMOS Output TRI-STATE IOZ nA Current VOUT = VD -25 CMOS DIGITAL OUTPUT DC SPECIFICATIONS (CMOS DATA OUTPUTS) VOH Logical “1” Output Voltage IOUT = -0.5 mA 2.3 V VOL Logical “0” Output Voltage IOUT = 1.6 mA 0.12 V VOUT = DGND 12 IOS Output Short Circuit Current mA VOUT= VD -14 VOUT = DGND 20 CMOS Output TRI-STATE IOZ nA Current VOUT = VD -25 (1) Test limits are ensured to TI's AOQL (Average Outgoing Quality Level). (2) Typical figures are at TA = 25°C, and represent most likely parametric norms at the time of product characterization. The typical specifications are not ensured. (3) The analog inputs are protected as shown in Figure 1. Input voltage magnitudes beyond the supply rails will not damage the device, provided the current is limited per Note 4 under the Absolute Maximum Ratings table. However, input errors will be generated If the input goes above VA and below AGND.
