Dual CMOS op-amp for battery-conscious signal chains
Each of its two channels draws just 375 µA from a supply ranging from 2.5 V to 5.5 V, making it a natural fit for single-cell lithium-ion or regulated 3.3 V systems. The 5.5 MHz gain-bandwidth product and 6 V/µs slew rate provide enough speed for audio processing, sensor conditioning, and active filtering without burning through the battery budget.
The 150 µV input offset voltage is tighter than many general-purpose CMOS parts — you can use it for DC-coupled precision circuits without an autozero loop, as long as the 0.2 pA input bias current doesn't drift into the megaohm range of your source impedance.
The base product number OPA2340 covers the family, and the UA/2K5 suffix specifies the 8-SOIC package in a 2500-piece reel.
