Texas Instruments OPA4243

The OPA4243 is a four-channel op amp specifically designed for high density, space-limited applications, such as LCD bias drivers, PCMCIA cards, batterypacks and portable instruments. In addition to small size, this part features wide output swing, very low quiescent current, and low bias current. Other features include unity gain stability and the best speed power ratio available. Power supplies in the range of 2.2V to 36V (±1.1V to ±18V) can be used.Each channel uses completely independent circuitry for lowest crosstalk and freedom from interaction, even when overloaded. In addition, the amplifier is free from output inversion when the inputs are driven to the rail. The OPA4243EA is supplied in the miniature TSSOP-14 surface mount package. Specifications apply from -40°C to +85°C. However, as the extensive typical performance curves indicate, the OPA4243 can be used over the full -55°C to +125°C range. A SPICE macromodel is available for design analysis.
