OPA2251 General Description

The OPA241 series and OPA251 series are specifically designed for battery powered, portable applications. In addi- tion to very low power consumption (25A), these amplifi- ers feature low offset voltage, rail-to-rail output swing, high common-mode rejection, and high open-loop gain.

The OPA241 series is optimized for operation at low power supply voltage while the OPA251 series is optimized for high power supplies. Both can operate from either single (+2.7V to +36V) or dual supplies (±1.35V to ±18V). The input common-mode voltage range extends 200mV below the negative supply°(TM)ideal for single-supply applications They are unity-gain stable and can drive large capacitive loads. Special design considerations assure that these prod- ucts are easy to use. High performance is maintained as the aplifiers swing to their specified limits. Because the initial offset voltage (±250V max) is so low, user adjustment is usually not required. However, external trim pins are pro- vided for special applications (single versions only).

The OPA241 and OPA251 (single versions) are available in standard 8-pin DIP and SO-8 surface-mount packages.

The OPA2241 and OPA2251 (dual versions) come in 8-pin DIP and SO-8 surface-mount packages. The OPA4241 and OPA4251 (quad versions) are available in 14-pin DIP and SO-14 surface-mount packages. All are fully specified from -40 to +85 and operate from -55 to +125.

OPA2251 Maximum Ratings

Supply Voltage, V+ to V-...................................................................36V
Input Voltage⁽²⁾...............................................(V-) -0.5V to (V+) +0.5V
Output Short Circuitto Ground⁽³⁾ ........................................Continuous
Operating Temperature..................................................-55 to +125
Storage Temperature.....................................................-55 to +125
Junction Temperature.....................................................................150
Lead Temperature (soldering, 10s)................................................300

NOTES: (1) Stresses above these ratings may cause permanent damage. (2) Input terminals are diode-clamped to the power supply rails. Input signals that can swing more that 0.5V beyond the supply rails should be current- limited to 5mA or less. (3) One amplifier per package.
