Quad CMOS op-amp for low-power signal chains
The Texas Instruments OPA4348AIDR contains four CMOS rail-to-rail op-amps in a 14-SOIC package. Each amplifier provides a 1 MHz gain-bandwidth product and a 0.5 V/µs slew rate.
Supply current and voltage — fit for battery and 5 V systems
Supply current is 45 µA per channel. The supply range spans 2.1 V to 5.5 V.
Temperature grade and environment
Rated for -40°C to 125°C, the OPA4348AIDR handles industrial enclosures, outdoor telecom cabinets, and under-hood automotive modules. The CMOS inputs draw only 0.5 pA of bias current, so high-impedance sensor signals (thermistors, photodiodes, pH probes) are not loaded down — a real advantage when the trace runs across a noisy PCB.
Output drive and input offset
Each output can source or sink 10 mA. Input offset voltage is trimmed to 1 mV.
