The OPA333A series of CMOS operational amplifiers uses a proprietary auto-calibration technique to

simultaneously provide very low offset voltage (10

µV max) and near-zero drift over time and temperature. These

miniature,

high-precision,

low-quiescent-current

amplifiers

offer

high-impedance

inputs

that

have

a

common-mode range 100 mV beyond the rails, and rail-to-rail output that swings within 50 mV of the rails. Single

or dual supplies as low as 1.8 V (±0.9 V) and up to 5.5 V (±2.75 V) may be used. They are optimized for

low-voltage single-supply operation.

The OPA333A family offers excellent common-mode rejection ratio (CMRR) without the crossover associated

with traditional complementary input stages. This design results in superior performance for driving

analog-to-digital converters (ADCs) without degradation of differential linearity.

The OPA333A (single version) is available in the SC70-5 and SOT23-5 packages. The OPA2333A (dual version)

is offered in the SO-8 package. All versions are specified for operation from –55°C to 125°C.

(1)

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating

conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

Input terminals are diode clamped to the power-supply rails. Input signals that can swing more than 0.3 V beyond the supply rails should

be current limited to 10 mA or less.

(3)

Short circuit to ground, one amplifier per package

(4)

Long-term high-temperature storage and/or extended use at maximum recommended operating conditions may result in a reduction of

overall device life. See http://www.ti.com/ep_quality for additional information on enhanced plastic packaging.
