Introducing LPV324 Bare Die Product
Ultra Low Power Consumption Operational Amplifier

The LPV324 bare die is a low power (9 µA per channel at 5.0V) version of the LMV324 op amp and is particularly suited for Medical Sensing applications. The LPV324 bare die is the most effective solution for medical applications where low voltage, low power operation and space saving are critical. The LPV324 bare die has rail-to-rail output swing capability and the input common-mode voltage range includes ground. The LPV324 bare die exhibits excellent speed-power ratio, achieving 5 kHz of bandwidth with a supply current of only 9 µA. Designing medical applications with the LPV324 in die form also allows the designer to place the device closer to the signal source to reduce noise pickup and increase signal integrity. The chip is built with National's advanced submicron silicon-gate BiCMOS process. The LPV324 has bipolar input and output stages for improved noise performance and higher output current drive. Features (For V+ = 5V and V- = 0V, typical unless otherwise noted) Guaranteed 2.7V and 5V performance No crossover distortion Bare Die smallest form factor 610μm x 965μm Reduced interconnect increases mechanical reliability Industrial temperature range -40°C to +85°C Gain-bandwidth product 152 kHz Low supply current 28 µA Rail-to-rail output swing @ 100 k.
