OPA343NA/3KG4 Description

Short technical summary and product information.

The OPA343NA/3KG4 from Texas Instruments is a single-supply, rail-to-rail CMOS operational amplifier optimized for low-cost, miniature applications. It operates on a single supply as low as 2.5V, with its input common-mode voltage range extending 500mV beyond the supply.

 

Key electrical characteristics include a wide bandwidth of 5.5MHz, a high slew rate of 6V/us, and low total harmonic distortion plus noise of 0.0007% at 1kHz. The quiescent current is 850uA per channel.

 

This operational amplifier is suitable for driving sampling Analog-to-Digital (A/D) converters due to its rail-to-rail input/output and high-speed operation. It is also well-suited for general-purpose and audio applications, as well as providing I/V conversion at the output of Digital-to-Analog (D/A) converters.

 

The OPA343NA/3KG4 comes in a compact SOT-23 package with 5 pins, designed for surface mounting. The operating temperature range is -40°C to 85°C, and it is supplied in a standard package quantity of 3,000 units on tape and reel.
