Quad op-amp for low-power signal chains
Each of the four amplifiers draws 45 µA typical supply current, making this part a fit for battery-powered instrumentation, sensor interfaces, and multi-channel filter banks that cannot budget much power per channel. The 1 MHz gain-bandwidth product supports audio-band processing and low-frequency control loops, while the rail-to-rail output stage preserves dynamic range when running from a 2.1 V to 5.5 V single supply.
At 45 µA per channel, the full quad draws roughly 180 µA quiescent. In a 3.3 V system that is under 0.6 mW for all four amplifiers — negligible in a multi-rail design but a real saving in a single-cell or energy-harvesting node. The 10 pA input bias current (typical) keeps the part usable with high-impedance sources like photodiodes or pH probes without adding a noticeable offset from bias current flowing through the source resistance. Input offset voltage is specified at 800 µV maximum, which is adequate for 8- to 10-bit accuracy over the full temperature range.
Rail-to-rail output and supply range
The rail-to-rail output swings within millivolts of each supply rail, so a 3.3 V single-supply system can deliver a 3.2 V peak-to-peak signal without clipping.
Package and temperature grade
For designs that need wider temperature, consider the TLV9351IDCKR or OPA4374AIPWT, both rated to 125°C.
