Additionally, the LMV831/LMV832/LMV834 are EMI hardened to • Input Offset Voltage 1 mV Max minimize any interference so they are ideal for EMI • Input Bias Current 0.1 pA sensitive applications. • GBW 3.3 MHz The unity gain stable LMV831/LMV832/LMV834 • EMIRR at 1.8 GHz 120 dB feature 3.3 MHz of bandwidth while consuming only • Input Noise Voltage at 1 kHz 12 nV/ √Hz 0.24 mA of current per channel. These parts also maintain stability for capacitive loads as large as 200 • Slew Rate 2 V/µs pF. The LMV831/LMV832/LMV834 provide superior • Output Voltage Swing Rail-to-Rail performance and economy in terms of power and • Output Current Drive 30 mA space usage. • Operating Ambient Temperature Range −40°C This family of parts has a maximum input offset to 125°C voltage of 1 mV, a rail-to-rail output stage and an input common-mode voltage range that includes APPLICATIONS ground. Over an operating range from 2.7V to 5.5V the LMV831/LMV832/LMV834 provide a PSRR of 93 • Photodiode Preamp dB, and a CMRR of 91 dB. The LMV831 is offered in • Piezoelectric Sensors the space saving 5-Pin SC70 package, the LMV832 in the 8-Pin VSSOP and the LMV834 is offered in the • Portable/Battery-Powered Electronic 14-Pin TSSOP package. Equipment • Filters/Buffers • PDAs/Phone Accessories Typical Application Figure 1.
