Single-supply general-purpose op amp in SOT-23-5
The OPA387DBVR is a single-circuit general-purpose operational amplifier from Texas Instruments, packaged in a 5-pin SOT-23-5 (SC-74A) surface-mount package. It delivers a 5.7 MHz gain-bandwidth product and a 2.8 V/µs slew rate, making it suitable for signal conditioning in sensor interfaces, ADC drivers, and general analog processing where moderate bandwidth and low power are required.
Supply range and rail-to-rail output
Operating from a single supply as low as 1.7 V up to 5.5 V, this op amp covers the full range of 3.3 V and 5 V logic rails while also supporting lower-voltage battery applications. The rail-to-rail output stage swings within millivolts of both supply rails, preserving dynamic range in low-voltage designs. Input offset voltage is 250 µV typical, and input bias current is just 30 pA, which minimizes DC errors in high-impedance sensor circuits. The device draws 570 µA quiescent supply current per amplifier, balancing speed with power efficiency for always-on or battery-powered systems. Each output can source or sink 55 mA, sufficient to drive moderate loads like a 2 kΩ reference or a small analog multiplexer. The -40°C to 125°C operating temperature range qualifies it for industrial and automotive under-hood environments.
