Product Announcement Introducing LPV324 Bare Die Product from National Semiconductor Ultra Low Power Consumption Operational Amplifier The LPV324 is a low power (9 µA per channel at 5.0V) version of the LMV324 op amp particularly suited for Medical Sensing applications as bare die. The LPV324 is the most effective solution for medical applications where low voltage, low power operation and space saving are critical. The LPV324 has rail-to-rail output swing capability and the input common-mode voltage range includes ground. The LPV324 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 bare 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.
