Overview
The TSZ182IDT from STMicroelectronics is a dual operational amplifier known for its very low offset voltages and virtually zero drift versus temperature changes. This device offers rail-to-rail input and output, an excellent speed/power consumption ratio, and a 3 MHz gain bandwidth product, all while consuming just 1 mA at 5 V. It also features an ultra-low input bias current, making it ideal for high-accuracy, high-bandwidth sensor interfaces.
