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 than 0.5V beyond the supply rails should be current- limited to 10mA or less. (3) Short-circuit to ground, one amplifier per package.
DescriptionOPA340 series rail-to-rail CMOS operational amplifi- ers are optimized for low voltage, single supply opera- tion. Rail-to-rail input/output and high speed operation make them ideal for driving sampling analog-to-digital converters. They are also well suited for general pur- pose and audio applications as well as providing I/V conversion at the output of D/A converters. Single, dual, and quad versions have identical specifications for design flexibility.
The OPA340 series operates on a single supply as low as 2.5V with an input common-mode voltage range that extends 500mV below ground and 500mV above the positive supply. Output voltage swing is to within 1mV of the supply rails with a 100k? load. They offer excel- lent dynamic response (BW = 5.5MHz, SR = 6V/s), yet quiescent current is only 750?A. Dual and quad designs feature completely independent circuitry for lowest crosstalk and freedom from interaction.
The single (OPA340) packages are the tiny 5-lead SOT-23-5 surface mount, SO-8 surface mount, and pin DIP. The dual (OPA2340) comes in the minia- ture MSOP-8 surface mount, SO-8 surface mount, and 8-pin DIP packages. The quad (OPA4340) pack- ages are the space-saving SSOP-16 surface mount, SO-14 surface mount, and the 14-pin DIP. All are specified from -40 to +85 and operate from -55 to +125. A SPICE macromodel is available for design analysis.
