OPA2990IDSGR – TEXAS INSTRUMENTS

The Texas Instruments OPA2990IDSGR is a single, precision, rail-to-rail input/output operational amplifier packaged in a space-saving 8-pin SOIC (small outline integrated circuit) surface-mount package. It boasts a wide, single-supply voltage range of 2.5V to 5.5V, enabling its use in low-voltage applications. Its key specifications include a typical input offset voltage of 25µV, a low input bias current of 10nA, and a fast settling time of 1.2µs. This translates to exceptional accuracy and speed in signal processing. The OPA2990IDSGR exhibits excellent common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR), minimizing noise and ensuring stable performance even under varying power supply conditions._x000D_

Common use cases include precision instrumentation amplifiers, low-noise sensor interfaces, and high-resolution data acquisition systems. Its rail-to-rail capabilities are particularly advantageous in applications requiring the full dynamic range of the supply voltage, maximizing signal swing. The low input bias current ensures minimal loading on high-impedance sources. The device’s superior performance characteristics make it ideal for applications demanding high accuracy and low distortion, especially in battery-powered devices where power consumption is critical. Its small form factor contributes to compact circuit designs.
