DESCRIPTION

OPA336 series

microPower 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

Ω 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

(20

µA/amplifier), they feature low offset voltage

(125

µV 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 come in the miniature

MSOP-8 surface-mount, SO-8 surface-mount, and DIP-8

packages. The OPA4336 package 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.
