OPAx244 MicroAmplifier™ Op Amps

Texas Instruments OPAx244 MicroAmplifier™ Operational Amplifiers (Op Amps) are designed for very low quiescent current (50µA/channel) yet achieve excellent bandwidth. These devices are available in single (OPA244), dual (OPA2244), and quad (OPA4244) versions. These op amps are ideal for battery-powered and portable instrumentation, and all versions are offered in micro packages for space-limited applications. The dual and quad versions feature completely independent circuitry for the lowest crosstalk and freedom from interaction, even when overdriven or overloaded.
