LM2904ST

Instrumentation, Op Amps, Buffer Amps Overview

The LM2904ST is a dual operational amplifier manufactured by STMicroelectronics, housed in an 8-MiniSO surface-mount package. It features two independent high-gain circuits with internal frequency compensation designed for automotive and industrial control applications. The device operates on a single power supply ranging from +3 V to +30 V, with an input common-mode voltage range that includes ground. Key electrical parameters include a gain-bandwidth product of 700 kHz, a slew rate of 0.6 V/µs, and a maximum output current of 30 mA per channel. Supply current is 700 µA, with an input bias current of 20 nA and input offset voltage of 2 mV.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Internal frequency compensation ensures stability in high-gain configurations without external components.
• Input common-mode voltage range extends to ground, allowing direct interfacing with low-level signals.
• Single-supply operation simplifies power design across a wide voltage span.

Instrumentation, Op Amps, Buffer Amps Applications

• Automotive control systems
• Industrial process control
• General-purpose signal amplification

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package designation (8-MiniSO) against the target PCB footprint during procurement. Confirm RoHS compliance status and moisture sensitivity level requirements for the assembly line. Ensure the ordering suffix matches the required tape-and-reel or cut-tape format. Cross-reference the manufacturer part number with distributor databases to confirm current production status and availability constraints.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual op-amp solution is required with ground-referenced input capability and moderate bandwidth. The 700 kHz gain-bandwidth product suits general-purpose applications rather than high-speed signal processing. Consider the 8-MiniSO package dimensions for space-constrained designs. Evaluate the 30 mA output drive capability against load requirements before finalizing the selection.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the LM2904 family of low-power dual operational amplifiers. It shares functional similarities with other variants like the LM2904WDT but differs in packaging and specific electrical tolerances. The MiniSO form factor provides a compact alternative to standard SOIC packages while maintaining comparable performance characteristics for industrial and automotive environments.
