RS8412XK

Overview

The RS8412XK is a dual-channel CMOS operational amplifier manufactured by Runic Technology. It operates within a supply voltage range of 3V to 36V (or ±1.5V to ±18V) and features rail-to-rail output capability. Key electrical specifications include a gain-bandwidth product of 1.2MHz, a slew rate of 0.67V/µs, and a typical input offset voltage of ±0.8mV. The device draws a quiescent current of 150µA per amplifier and maintains stability with capacitive loads up to 300pF. It is housed in an 8-SOIC package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Rail-to-rail output stage for maximum dynamic range
• Ultra-low input bias current suitable for high-impedance sources
• Unity-gain stable with excellent speed-to-power ratio
• Common-mode input voltage range includes ground potential

Applications

• Sensor signal conditioning
• Photodiode amplification circuits
• Active filter implementations
• Test and measurement equipment
• Driving analog-to-digital converters

Procurement Notes

Verify the specific ordering suffix 'K' corresponds to the SOIC-8 package variant when sourcing. Confirm that the component meets RoHS3 compliance requirements if applicable to your manufacturing standards. Ensure the selected supplier provides valid traceability documentation for the lot code and vendor information printed on the device marking.

Selection Notes

Select this component for applications requiring high-voltage operation up to 36V combined with low power consumption. The rail-to-rail output and ground-referenced common-mode input make it suitable for single-supply systems. Verify that the 1.2MHz bandwidth and 0.67V/µs slew rate meet the signal processing requirements of the target circuit design.

Part Context

The RS8412XK belongs to the RS841X family of operational amplifiers, which also includes single-channel (RS8411) and quad-channel (RS8414) variants. This family shares core architectural characteristics such as CMOS technology, high voltage tolerance, and rail-to-rail performance. The RS8412 specifically integrates two independent amplifiers into a compact 8-pin surface-mount package.

Replacement Considerations

Public datasheets indicate compatibility with MCP6H02, TLV2170, OPA2137, OPA2170, TLV9302, and ADA4665-2. Verify pinout alignment and electrical parameter margins before substitution.
