Description
General part information
OPA2391 Series
The OPA391, OPA2391, and OPA4391 (OPAx391) devices feature a unique combination of high bandwidth (1MHz) along with very-low quiescent current (24µA) in high-precision amplifiers. These features combined with rail-to-rail input and output make these devices an exceptional choice in high-gain, low-power applications. Ultra-low input bias current of 10fA, only 45µV of offset (maximum), and 1.2µV/°C of drift over temperature help maintain high precision in ratiometric and amperometric sensor front ends that have demanding low-power requirements.
The OPAx391 use Texas Instruments’ proprietary e‑trim™ operational amplifier technology, enabling a unique combination of ultra-low offset and low input offset drift without the need for any input switching or auto-zero techniques. The CMOS-based technology platform also features a modern, robust output stage design that is tolerant of high output capacitance, alleviating stability problems that are common in typical low-power amplifiers.
