ES8552-SR

The ES8552-SR high-voltage general-purpose op-amp from Jingxin Micro is manufactured using advanced processes with full automotive-grade standard control throughout the entire production flow, available in single, dual, and quad op-amp configurations. Featuring proprietary circuit design techniques with classic rail-to-rail input/output swing, it delivers high consistency and symmetry across the full operating voltage and temperature range, making it ideal for cost-sensitive and space-constrained applications while providing excellent overall circuit compatibility. The ES8552-SR integrates an overload protection circuit that enables the amplifier to activate a recovery function under overload conditions and resume normal operation within a short period, greatly enhancing circuit reliability. The 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, particularly suited for space-critical applications. These devices contain 4 independent high-gain frequency-compensated op-amps, designed specifically 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 amplifier stages, and all conventional op-amp circuits, which can now be more easily implemented in single-supply voltage systems. Slew rate refers to the rate at which an op-amp can change its output in response to an input change; the ES8552-SR 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 product of 1.0MHz. The ES8552-SR achieves low input offset voltage under high-voltage supply conditions, with a typical value as low as 0.35mV. Minimizing offset voltage expands the op-amp's application scope and range, making it especially suitable for high-sensitivity applications. The op-amp is applicable to a wide variety of signal conditioning applications, allowing inputs to be powered prior to Vs for multi-supply circuit flexibility. An inverting amplifier converts a positive input voltage to a negative voltage of equal magnitude at the output, and likewise converts a negative input voltage to a positive voltage.
