description/ordering information The LPV321/358/324 devices are low-power (9 µA per channel at 5 V) versions of the LMV321/358/324 operational amplifiers. These are additions to the LMV321/358/324 family of commodity operational amplifiers. The LPV321/358/324 devices are the most cost-effective solutions for applications where low voltage, low-power operation, space saving, and low price are needed. These devices have rail-to-rail output-swing capability, and the input common-mode voltage range includes ground. They all exhibit excellent speed-power ratios, achieving 152 k Hz of bandwidth, with a supply current of only 9 µA typical. The LPV321, LPV358, and LPV324 are characterized for operation from −40°C to 85°C. The LPV321I, LPV358I, and LPV324I are characterized for operation from −40°C to 125°C.
