DESCRIPTION
OPA336 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 100kΩ 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 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.
