Product Description

onsemi LM385D-2.5G is a Fixed Shunt Precision Virtual Ground IC designed to deliver a stable 2.5V reference voltage with high accuracy, making it ideal for power management and analog circuits where precise voltage referencing is critical. Housed in an 8-pin SOIC surface-mount package, this device offers reliable performance in compact board layouts, simplifying integration in modern electronics.

This integrated circuit uses a shunt topology, allowing it to establish a virtual ground with a fixed reference for applications ranging from industrial measurement systems to laboratory instrumentation. The ±3% initial accuracy combined with a low temperature coefficient of 80 ppm/°C means voltage drift is minimized under varying ambient conditions.

With a maximum output current capability of 20mA, the LM385D-2.5G supports moderate load requirements for analog circuitry, including reference nodes in data acquisition, signal conditioning, and calibration systems. The input voltage range from 2.43V to 2.58V provides flexibility when interfacing with multiple supply rails.

Additional technical features include an 8-pin count for easy soldering and board placement, a die height of 1.5mm and length of 5mm, and load regulation performance at 20mV. The IC is specified for operation from 0°C to 70°C, making it robust for both laboratory and industrial deployment.

This precision voltage reference is part of the LM385 series, engineered to meet demanding performance criteria and suitable for applications like instrumentation amplifiers, operational amplifiers, and ADC/DAC reference nodes. Automotive standard compliance is not indicated for this model.

Industrial, laboratory, and commercial electronics benefit from the stable, repeatable voltage output of the LM385D-2.5G, ensuring reliable signal integrity and accurate measurements. Its surface-mount design enhances manufacturability in automated PCB assembly.
