Texas Instruments OPA2486 Operational Amplifier
Texas Instruments OPA2486 Operational Amplifier is a 48V, low-noise, wide-bandwidth, low-power, zero-drift operational amplifier. This amplifier offers 5.6MHz gain bandwidth, 15V/µs slew rate, 9.2nV/√Hz low noise, and 0.3µVPP near-zero flicker noise. The OPA2486 operational amplifier provides common-mode and power-supply rejection, which enables high-precision measurements across a variety of operating conditions. This amplifier features a 4.5V to 48V wide operating supply range, 650µA maximum low quiescent current, 5µV input offset voltage (maximum), and 0.025µV/°C input offset voltage drift. The OPA2486 operational amplifier includes a proprietary MUX-friendly input design to enhance performance in multichannel and multiplexed applications. This amplifier is available in industry-standard package as well as micro-size package and operates at -40°C to 125°C temperature range. Typical applications include BBU for 12VDC or 48VDC, CRPS, analog input module, flow transmitter, pressure transmitter, merchant battery charger, and weigh scale.
