5.5 MHz CMOS dual op-amp with 0.6 pA input bias
The OPA2341DGSA/250 is a Texas Instruments MicroAmplifier™ CMOS dual operational amplifier, offering two rail-to-rail output circuits in a 10-VSSOP package. With a 5.5 MHz gain-bandwidth product and a 6 V/µs slew rate, this part handles moderate-speed signal conditioning — think sensor amplification, active filters, or data-acquisition front-ends where the signal bandwidth stays under a few hundred kilohertz. The 0.6 pA typical input bias current makes it suitable for high-impedance sources like photodiode transimpedance stages or pH probe buffers, where bias current errors would otherwise dominate the offset budget.
Supply range, output drive, and temperature grade
Operating from a 2.5 V to 5.5 V supply span, the OPA2341DGSA/250 fits single-supply 3.3 V or 5 V systems without needing a negative rail — the rail-to-rail output swings within millivolts of each supply, preserving dynamic range at low voltages. Each channel delivers up to 50 mA of output current, enough to drive a 100-ohm load or an ADC input stage directly, while the total quiescent supply is just 750 µA for both amplifiers — about 375 µA per channel, which keeps the thermal rise negligible in the 10-VSSOP package. Rated across the full military temperature range of -55°C to 125°C, this part is qualified for avionics, downhole instrumentation, or outdoor telecom enclosures where the ambient swings beyond industrial limits.
Active production and compliance status
The part is ROHS3 compliant, meeting the latest EU restriction-of-hazardous-substances directive for lead-free assembly.
