TLV2211IDBVR

The TLV2211IDBVR from Texas Instruments is a single micropower operational amplifier built on Advanced LinCMOS technology, optimized for battery-powered and low-voltage applications. Consuming only 11 uA typical supply current, it achieves a gain-bandwidth product of 65 kHz with rail-to-rail output capability that includes both supply rails for maximum dynamic range. The ultra-low input bias current of 1 pA typical makes it excellent for interfacing with high-impedance sources such as piezoelectric transducers and pH electrodes. The optimized SOT-23-5 pinout separates inputs by GND to minimize coupling and leakage paths.

The TLV2211IDBVR uses Advanced LinCMOS CMOS technology with a rail-to-rail output stage. The CMOS input pair provides extremely low input bias current (1 pA typical), critical for high-impedance sensor applications where input loading must be minimized. The rail-to-rail output stage uses common-source output transistors that can swing to within millivolts of both supply rails, maximizing dynamic range in single-supply applications. The internal compensation provides stability in unity-gain configurations. The low 11 uA quiescent current is achieved through careful bias circuit design, making it suitable for always-on battery-powered circuits.
