OPA353NA/3K

OPA353 series rail-to-rail CMOS operational amplifiers are designed for low cost, miniature applications. They are optimized for low voltage, single-supply operation. Rail-to-rail input/output, low noise (5nV/√Hz), and high speed operation (44MHz, 22V/µs) make them ideal for driving sampling analog-to-digital converters. They are also well suited for cell phone PA control loops and video processing (75Ω drive capability) as well as audio and general purpose applications. Single, dual, and quad versions have identical specifications for design flexibility. The OPA353 series operates on a single supply as low as 2.5V with an input common-mode voltage range that extends 300mV beyond the supply rails. Output voltage swing is to within 10mV of the supply rails with a 10kΩ load. Dual and quad designs feature completely independent circuitry for lowest crosstalk and freedom from interaction. The single (OPA353) packages are the tiny 5-lead SOT23-5 surface mount and SO-8 surface mount. The dual (OPA2353) comes in the miniature MSOP-8 surface mount and SO-8 surface mount. The quad (OPA4353) packages are the space-saving SSOP-16 surface mount and SO-14 surface mount. All are specified from -40°C to +85°C and operate from -55°C to +125°C.
