DESCRIPTION

OPA343 series rail-to-rail CMOS operational amplifiers

are designed for low-cost, miniature applications. They

are optimized for low-voltage, single-supply operation.

Rail-to-rail input/output and high-speed operation make

them ideal for driving sampling Analog-to-Digital (A/D)

converters. They are also well suited for general-purpose

and audio applications as well as providing I/V conver-

sion at the output of Digital-to-Analog (D/A) converters.

Single, dual, and quad versions have identical specifica-

tions for design flexibility.

The OPA343 series operates on a single supply as low as

2.5V, and input common-mode voltage range extends

500mV beyond the supply rails. Output voltage swings to

within 1mV of the supply rails with a 100kΩ load. They

offer excellent dynamic response (BW = 5.5MHz,

SR = 6V/µs), yet quiescent current is only 850µA. Dual

and quad designs feature completely independent circuitry

for lowest crosstalk and freedom from interaction.

The single (OPA343) packages are the tiny SOT-23-5

surface mount and SO-8 surface mount. The dual

(OPA2343) comes in the miniature MSOP-8 surface

mount and SO-8 surface mount. The quad (OPA4343)

packages are the space-saving SSOP-16 surface mount,

SO-14 surface mount, and TSSOP-14 surface mount. All

are specified from –40°C to +85°C and operate from

–55°C to +125°C. A SPICE macromodel is available for

design analysis.

APPLICATIONS INFORMATION OPERATING VOLTAGE OPA343 series op amps are fabricated on a state-of-the-art 0.6 micron CMOS process. They are unity-gain stable and suitable for a wide range of general-purpose applications. Rail-to-rail input/output make them ideal for driving sampling A/D converters. In addition, excellent ac performance makes them well-suited for audio applications. The class AB output stage is capable of driving 600Ω loads connected to any point between V+ and ground.

more than 500mV can cause excessive current to flow in or out of the input pins. Momentary voltages greater than 500mV beyond the power supply can be tolerated if the current on the input pins is limited to 10mA. This is easily accomplished with an input resistor, as shown in Figure 3. Many input signals are inherently current-limited to less than 10mA, therefore, a limiting resistor is not required.
