Overview
The TLV2761IDBVR is a single-supply operational amplifier from Texas Instruments, part of the TLV276x family. These micropower op-amps are designed to operate from a supply voltage as low as 1.8 V and up to 3.6 V, making them suitable for battery-powered devices and low-voltage applications. The TLV2761IDBVR offers a bandwidth of 500 kHz while consuming only 20 μA of supply current, making it highly efficient for power-sensitive designs. The device features rail-to-rail input and output capability, which is essential for applications where the signal can swing close to the supply rails. Additionally, the low shutdown current of 10 nA makes it ideal for applications requiring long battery life.
