LM258DGKRG4

Overview

The LM258DGKRG4 is a dual operational amplifier manufactured by Texas Instruments, housed in an 8-pin VSSOP package. It operates within a supply voltage range of 3 V to 32 V or ±1.5 V to ±16 V. Key electrical parameters include a gain-bandwidth product of 700 kHz and a slew rate of 300 mV/µs. The device features a maximum input offset voltage of 5 mV and an input bias current of 150 nA. Each channel provides an output current capability of 20 mA with a common-mode rejection ratio of 80 dB. The input type supports rail-to-rail operation, and the component functions without a shutdown mode.

Feature Summary

• Dual-channel architecture providing two independent high-gain amplifiers within a single compact surface-mount package.
• Rail-to-rail input functionality allowing signal processing across the full supply voltage range.
• Single-supply or split-supply compatibility enabling flexible integration into various power configurations.

Applications

• General-purpose analog signal conditioning circuits
• Transducer interface applications requiring low-voltage operation
• Sensor signal amplification in industrial control systems

Procurement Notes

Verify the specific suffix DGKR against official Texas Instruments documentation to confirm the VSSOP-8 packaging and tape-and-reel delivery format. Ensure that the procurement specifications align with the required operating temperature range of -25°C to +85°C. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and compliance with relevant environmental standards such as RoHS directives.

Selection Notes

Select this component when a dual operational amplifier with rail-to-rail input capabilities is required for space-constrained designs. The VSSOP-8 package offers a smaller footprint compared to traditional SOIC options while maintaining compatible pinouts. Consider the 20 mA output drive capability and 700 kHz bandwidth for applications involving moderate-speed signal processing tasks where low power consumption is a priority.
