TI’s LMV83x devices are CMOS input, low-power operation amplifier ICs, providing a low input bias current, a wide temperature range of −40°C to 125°C, and exceptional performance, making them robust general-purpose parts. Additionally, the LMV83x are EMI-hardened to minimize any interference, making them ideal for EMI-sensitive applications.

The unity gain stable LMV83x feature 3.3-MHz of bandwidth while consuming only 0.24 mA of current per channel. These parts also maintain stability for capacitive loads as large as 200 pF. The LMV83x provide superior performance and economy in terms of power and space usage.

This family of parts has a maximum input offset voltage of 1 mV, a rail-to-rail output stage and an input common-mode voltage range that includes ground. Over an operating range from 2.7 V to 5.5 V, the LMV83x provide a PSRR of 93 dB, and a CMRR of 91 dB. The LMV831 is offered in the space-saving 5-pin SC70 package, the LMV832 in the 8-pin VSSOP and the LMV834 is offered in the 14--in TSSOP package.
