LM2904DR(ES)

Jingxin Micro's high-voltage general-purpose op-amp LM2904DR(ES) is manufactured using advanced processes with full-flow automotive-grade quality control, available in single, dual, and quad configurations. Utilizing proprietary circuit design techniques, it features classic rail-to-rail input/output swing with high consistency and symmetry across the full operating voltage and temperature range, making it suitable for cost-sensitive and space-constrained applications while providing balanced integration with overall circuit designs. The op-amp incorporates a built-in overload protection circuit that activates recovery functionality during overload conditions and restores normal operation within a short period, enhancing circuit reliability. Available in industry-standard packages including SOP, MSOP, SOT-23, and TSSOP; the quad op-amp (ESLM324A) also offers a unique QFN16 3×3 package for space-critical applications. These devices contain 4 independent high-gain frequency-compensated op-amps designed for single-supply operation over a wide voltage range, with dual-supply operation also supported. The low supply current drain is independent of supply voltage magnitude. Typical applications include sensor amplifiers, DC gain blocks, and all traditional op-amp circuits, which can be more easily implemented in single-supply voltage systems. With a slew rate of 1.0 V/μs and a bandwidth of 1.0 MHz, the device achieves a typical input offset voltage as low as 0.35 mV under high-voltage supply conditions, expanding its application scope and range, particularly suited for high-sensitivity applications. The op-amp is applicable to various signal conditioning applications and can accept input signals prior to Vs, enabling flexibility in multi-supply circuits. An inverting amplifier converts a positive input voltage to a negative voltage of equal magnitude, and likewise converts a negative input voltage to a positive voltage.
