OPA991IDBVR – TEXAS INSTRUMENTS

The Texas Instruments OPA991IDBVR is a single, precision, rail-to-rail input/output operational amplifier packaged in a small, space-saving 8-lead SOIC (DBV) surface-mount package. Operating from a ±15V to ±30V supply, or a single 30V to 60V supply, it boasts a remarkably low input bias current of only 1 pA maximum, crucial for high-impedance applications. Its ultra-low input offset voltage of ±25µV (max) contributes to superior accuracy in instrumentation and measurement circuits. The OPA991IDBVR features a wide bandwidth of 1.5MHz, enabling high-speed signal processing, while maintaining a low noise figure of 2.5nV/√Hz. Its rail-to-rail capabilities maximize dynamic range, eliminating the need for additional level-shifting circuitry. Typical applications leverage its precision characteristics in high-resolution data acquisition systems, precision instrumentation amplifiers, and low-noise sensor interfaces demanding minimal offset drift. The device’s high common-mode rejection ratio (CMRR) of 100dB further enhances its suitability for noisy environments. Its robust performance across a wide temperature range (-40°C to +125°C) makes it ideal for demanding industrial and automotive applications.
