3 / 31 page  LMP2234 www.ti.com SNOSAW4D – SEPTEMBER 2007 – REVISED MARCH 2013 Operating Ratings (1) Operating Temperature Range (2) −40°C to 125°C Supply Voltage (VS = V + - V–) 1.6V to 5.5V Package Thermal Resistance ( θJA) (2) 14-Pin SOIC 101.5 °C/W 14-Pin TSSOP 121 °C/W (1) Absolute Maximum Ratings indicate limits beyond which damage may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not ensured. For ensured specifications and test conditions, see the 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. 5V DC Electrical Characteristics (1) Unless otherwise specified, all limits are ensured for TA = 25°C, V + = 5V, V– = 0V, V CM = VO = V +/2, and R L > 1 MΩ. Boldface limits apply at the temperature extremes.

Factory testing conditions result in very limited self-heating of the device such that TJ = TA. No ensured specification of parametric performance is indicated in the electrical tables under conditions of internal self-heating where TJ > TA. Absolute Maximum Ratings indicate junction temperature limits beyond which the device may be permanently degraded, either mechanically or electrically. (2) All limits are specified by testing, statistical analysis or design. (3) Typical values represent 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. (4) The short circuit test is a momentary open loop test. Copyright © 2007–2013, Texas Instruments Incorporated Submit Documentation Feedback 3 Product Folder Links: LMP2234 |
