LM2904DT(ES)

Jingxin Micro's high-voltage general-purpose op-amp LM2904DT(ES) is manufactured using an advanced process with full automotive-grade quality control throughout the entire production flow, available in single, dual, and quad configurations. Featuring proprietary circuit design techniques, it delivers classic rail-to-rail input/output swing with excellent consistency and symmetry across the full operating voltage and temperature range. Ideal for cost-sensitive, space-constrained applications, it provides well-balanced coordination across the overall circuit design. The LM2904DT(ES) integrates an 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) also offers a unique QFN16 3×3 package, making it particularly suitable for space-critical applications. These devices contain 4 independent, high-gain, frequency-compensated op-amps designed to operate from a single supply 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 value of the input common-mode voltage. The low supply current drain is independent of the magnitude of the supply voltage. Typical applications include sensor amplifiers, DC amplifier stages, 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 a change at the input. The LM2904DT(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 is measured. These devices provide a high gain-bandwidth product of 1.0MHz. The LM2904DT(ES) offers low input offset voltage under high-voltage supply conditions, with a typical value as low as 0.35mV. For a high-voltage general-purpose op-amp, minimizing the offset voltage while balancing other op-amp parameters maximizes the range of applicable scenarios, making it especially suitable for high-sensitivity applications. Op-amps are suited for a wide variety of signal conditioning applications. Inputs can be powered prior to Vs, enabling flexible multi-supply circuit configurations. The amplifier accepts a positive voltage at its input and converts it to a negative voltage of equal magnitude. It similarly converts a negative input voltage to a positive voltage.
