OPA350

MicroAmplifierTM 系列高速单电源轨至轨运算放大器

The series of rail-to-rail CMOS operational amplifiers are optimized for low voltage, single-supply operation. Rail-to-rail input and output, low noise 5 nV/√Hz, and high speed operation 38 MHz, 22 V/µs make the amplifiers ideal for driving sampling Analog-to-Digital A/D converters. They are also suited for cell phone PA control loops and video processing 75-Ω drive capability, as well as audio and general purpose applications. Single, dual, and quad versions have identical specifications for maximum design flexibility.

The OPA350 series operates on a single supply as low as 2.5 V, with an input common-mode voltage range that extends 300 mV below ground and 300 mV above the positive supply. Output voltage swing is to within 10 mV of the supply rails, with a 10-kΩ load. Dual and quad designs feature completely independent circuitry for lowest crosstalk and freedom from interaction.

The single OPA350 and dual OPA2350 come in the miniature MSOP-8 surface mount, SO-8 surface mount, and DIP-8 packages. The quad OPA4350 packages are in 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 150°C.
