GENERAL DESCRIPTION

The OPA340 series operate on a single supply as low as 2.5 V with an input common-mode voltage range
that extends 500 mV below ground and 500 mV above the positive supply. Output voltage swing is to
within 1 mV of the supply rails with a 100-kΩ load. These devices offer excellent dynamic response
(BW = 5.5 MHz, SR = 6 V/µs), 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-pin SOT-23 surface mount, 8-pin SOIC surface mount,
and 8-pin DIP. The dual (OPA2340) comes in the miniature 8-pin VSSOP surface mount, 8-pin SOIC
surface mount, and 8-pin PDIP packages. The quad (OPA4340) packages are the space-saving 16-pin
SSOP surface mount and 14-pin SOIC 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.
