OPA336

MicroAmplifierTM 系列单电源、微功耗 CMOS 运算放大器

series _micro_Power CMOS operational amplifiers are designed for battery-powered applications. They operate on a single supply with operation as low as 2.1V. The output is rail-to-rail and swings to within 3mV of the supplies with a 100k load. The common-mode range extends to the negative supply—ideal for single-supply applications. Single, dual, and quad versions have identical specifications for maximum design flexibility.

In addition to small size and low quiescent current 20µA/amplifier, they feature low offset voltage 125µV max, low input bias current 1pA, and high open-loop gain 115dB. Dual and quad designs feature completely independent circuitry for lowest crosstalk and freedom from interaction.

OPA336 packages are the tiny SOT23-5 surface mount and SO-8 surface-mount. OPA2336 comes in the miniature MSOP-8 surface-mount, SO-8 surface-mount, and DIP-8 packages. The OPA4336 packages is the space-saving SSOP-16 surface-mount.

All are specified from –40°C to +85°C and operate from –55°C to +125°C. A macromodel is available for download at www.ti.com for design analysis.
