3 / 40 page  LMP8358 www.ti.com SNOSB09B – APRIL 2010 – REVISED MARCH 2013 Operating Ratings (1) Temperature Range −40°C to 125°C Supply Voltage (VS = V + – V−) 2.7V to 5.5V VIN Differential (V+IN − V−IN) ±100mV Package Thermal Resistance ( θJA (2)) 14-Pin SOIC 145°C/W 14-Pin TSSOP 135°C/W (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but for which specific performance is not ensured. For ensured specifications and the test conditions, see Electrical Characteristics. (2) The maximum power dissipation is a function of TJ(MAX), θJA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX) – TA)/ θJA. All numbers apply for packages soldered directly onto a PC Board. 3.3V Electrical Characteristics Unless otherwise specified, all limits are ensured for TA = 25°C. V + = 3.3V , V− = 0V, V REF = V +/2, V CM = V +/2, R L = 10 kΩ to VREF, CL = 10 pF; Serial Control Register: G[2:0] = 110b (Gain = 1000x), COMP[2:0] = 000b, MUX[1:0] = 00b, POL, SHDN, FILT, PIN = 0b, CUR[2:0] = 000b. Boldface limits apply at the temperature extremes.

(2) Typical Values indicate the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped production material. (3) The offset voltage average drift is determined by dividing the value of VOS at the temperature extremes by the total temperature change.
