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.
