The OPA244 (single), OPA2244 (dual), and OPA4244 (quad)op amps are designed for very low quiescent current(50mA/channel), yet achieve excellent bandwidth. Ideal forbattery powered and portable instrumentation, all versions areoffered in micro packages for space-limited applications.The dual and quad versions feature completely independentcircuitry for lowest crosstalk and freedom from interaction, evenwhen overdriven or overloaded.The OPA244 series is easy to use and free from phaseinversion and overload problems found in some other op amps.These amplifiers are stable in unity gain and excellent performanceis maintained as they swing to their specified limits.They can be operated from single (+2.2V to +36V) or dualsupplies (±1.1V to ±18V). The input common-mode voltagerange includes ground—ideal for many single supply applications.All versions have similar performance. However, thereare some differences, such as common-mode rejection. Allversions are interchangeable in most applications.All versions are offered in miniature, surface-mount packages.OPA244 (single version) comes in the tiny 5-lead SOT-23-5surface mount, SO-8 surface mount, and 8-pin DIP. OPA2244(dual version) is available in the MSOP-8 surface mount,SO-8 surface-mount, and 8-pin DIP. The OPA4244 (quad)comes in the TSSOP-14 surface mount. They are fully specifiedfrom –40°C to +85°C and operate from –55°C to +125°C.A SPICE Macromodel is available for design analysis.
