Other key specifications are a PSRR of 105 dB, CMRR of 120 dB, VOS of 500 μV, input referred • PSRR 105 dB voltage noise of 14 nV/ , and a THD of 0.002%. • Input Referred Voltage Noise 14 nV/ √Hz This amplifier has a rail-to-rail output stage, and a • 1/f Corner Frequency 4 Hz common mode input voltage which includes the negative supply. • Output Swing with 2 k Ω Load 40 mV from Rail • Total Harmonic Distortion 0.002% @ 1kHz, 2k Ω The LMV641 operates over a temperature range of −40°C to +125°C and is offered in the board space • Temperature Range −40°C to 125°C saving 5-Pin SC70, SOT-23, and 8-Pin SOIC packages. APPLICATIONS • Portable equipment • Battery powered systems • Sensors and instrumentation Figure 1. Offset Voltage Distribution Figure 2. Open Loop Gain and Phase vs. Frequency These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
