ElecSuper LM2904DR2G(ES)

Jingxinwei's high-voltage general-purpose op-amp LM2904DR2G(ES) is manufactured using advanced processes with full-flow automotive-grade standard control, available in single, dual, and quad configurations. Featuring proprietary circuit design techniques, it delivers classic rail-to-rail input/output swing with high consistency and symmetry across the full operating voltage and temperature range. It is well-suited for cost-sensitive and space-constrained applications, providing excellent overall circuit compatibility and balance.

The LM2904DR2G(ES) incorporates a built-in overload protection circuit that enables the amplifier to initiate a recovery function under overload conditions and resume normal operation within a short period, greatly enhancing circuit reliability.

This op-amp is available in industry-standard packages including SOP, MSOP, SOT-23, and TSSOP. The quad op-amp (ESLM324A) additionally offers a unique QFN16 3×3 package, making it especially suitable for space-critical applications.

These devices contain 4 independent high-gain frequency-compensated op-amps, designed primarily for single-supply operation over a wide voltage range. Dual-supply operation is also supported when the voltage difference between the two supplies is between 3V and 36V, and VCC is at least 1.5V above the positive common-mode input voltage. The low supply current drain is independent of the supply voltage magnitude. Typical applications include sensor amplifiers, DC gain blocks, and all conventional op-amp circuits, which can now be more easily implemented in single-supply voltage systems.

Slew rate is the rate at which an op-amp can change its output in response to an input change. The LM2904DR2G(ES) features a slew rate of 1.0 V/μs.

Gain-bandwidth product equals the measured amplifier bandwidth multiplied by the gain at which that bandwidth was measured. These devices offer a high gain bandwidth of 1.0MHz.

The LM2904DR2G(ES) provides low input offset voltage under high-voltage supply conditions, with a typical value as low as 0.35mV. Since the input offset voltage is amplified by the noise gain, it produces an offset error at the output. For a high-voltage general-purpose op-amp, minimizing the offset voltage while balancing other op-amp parameters maximizes the range of applicable use cases, making it particularly suitable for high-sensitivity applications.
