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 5-lead SOT-23-5 surface mount and SO-8 surface mount. The dual (OPA2343) comes in the miniature MSOP8 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. OPA4343 OPA4343 Out A 1 2 A D 12 11 10 B C 9 8 TSSOP-14 –In C Out C +In D V– +In C 3 4 5 6...
