OPAx991 Low-Noise Operational Amplifiers

Texas Instruments OPAx991 Low-Noise Operational Amplifiers (Op Amps) are high voltage (40V) general-purpose op amps. These are available in single (OPA991), dual (OPA2991), and quad (OPA4991) versions. These devices offer exceptional DC precision and AC performance, including rail-to-rail input/output, low offset (±125µV, typ), low offset drift (±0.3µV/°C, typ), low noise (10.5nV/√Hz and 1.8µVPP) and 4.5MHz bandwidth. These devices have unique features such as differential and common-mode input-voltage range to the supply rail, high output current (±75mA), high slew rate (21V/µs), high capacitive load drive (1nF) and shutdown functionality. This makes the OPAx991 a robust, high-performance operational amplifier for high-voltage industrial applications. The OPAx991 family of op amps is available in micro-size packages (such as X2QFN, WSON, and SOT-553), as well as standard packages (such as SOT-23, SOIC, and TSSOP), and is specified from –40°C to 125°C.
