Overview
The OPA369AIDCKR is an ultra-low-power, low-voltage operational amplifier from Texas Instruments, designed specifically for battery-powered applications. This amplifier features a zerø-crossover design, which resolves the issue of input crossover distortion common in low-voltage, rail-to-rail input applications. It operates on a supply voltage as low as 1.8V and is available in a micro-size SC70-5 package, making it ideal for a wide range of portable and low-power devices.
