产品概述 返回TOP
The CXOA4216/CXOA4217 are low voltage (2.7–5.5V) versions of the dual and quad commodity op amps, CXOA4211/CXOA4217, which currently operate at 5–30V. The CXOA4214 is the single version. The CXOA4214/CXOA4216/CXOA4217 are the most cost effective solutions for the applications where low voltage operation, space saving and low price are needed. They offer specifications that meet or exceed the familiar CXOA4211/CXOA4217. The CXOA4214/CXOA4216/CXOA4217 have rail-to-rail output swing capability and the input common-mode voltage range includes ground. They all exhibit excellent speed to power ratio, achieving 1 MHz of bandwidth and 1 V/μs of slew rate with low supply current. The CXOA4214 is available in the space saving 5-Pin SC70, which is approximately half the size of the 5-Pin SOT23. The small package saves space on PC boards, and enables the design of small portable electronic devices. It also allows the designer to place the device closer to the signal source to reduce noise pickup and increase signal integrity. The chips are built with National's advanced submicron silicon-gate BiCMOS process. The CXOA4214/CXOA4216/CXOA4217 have bipolar input and output stages for improved noise performance and higher output current drive.
