MAX202IDR – TEXAS INSTRUMENTS

The MAX202IDR is a low-power, high-performance, single-supply operational amplifier from Maxim Integrated. Specifically, it’s a micropower CMOS op-amp designed for applications requiring minimal current consumption while maintaining excellent performance characteristics. Operating from a single supply voltage typically ranging from 2.7V to 5.5V, the MAX202IDR boasts a low input bias current of only 1pA (typical) and a low input offset voltage of ±5µV (typical), making it ideal for high-precision applications. Packaged in a space-saving 8-pin SOIC, it offers a unity-gain bandwidth of 1MHz and a slew rate of 0.2V/µs._x000D_

Its low power consumption (typically 120µA at ±5V) makes it suitable for battery-powered devices and portable equipment. Common use cases include precision instrumentation amplifiers, sensor interface circuits, and low-power analog signal processing. The MAX202IDR’s advantages lie in its exceptionally low input bias current, which minimizes offset errors in high-impedance applications, and its wide single-supply voltage range, offering design flexibility. Furthermore, its small package size contributes to compact circuit board layouts. However, designers should be aware of its relatively modest slew rate, which may limit its performance in high-speed applications.
