LM2904A(ES)

Manufactured using advanced processes with full-process automotive-grade standard controls, available in single, dual, and quad op-amp configurations. Employing proprietary circuit design techniques, these devices feature classic rail-to-rail input/output swing with high consistency and symmetry across the full operating voltage and temperature range. Suitable for cost-sensitive and space-constrained applications, providing excellent coordination and compatibility within overall circuit designs. The built-in overload protection circuit enables the amplifier to activate a recovery function under overload conditions and resume normal operation within a short period, greatly 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. 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 LM2904A(ES) features a slew rate of 1.0 V/μs. Gain-bandwidth product equals the measured amplifier bandwidth multiplied by the gain at that bandwidth; these devices offer a high gain-bandwidth of 1.0 MHz. The LM2904A(ES) provides low input offset voltage under high-voltage supply conditions, with a typical value as low as 0.35 mV. The minimized offset voltage design maximizes the op-amp's application scope and range, making it especially suitable for high-sensitivity applications. The op-amp supports various signal conditioning applications and allows inputs to be powered before Vs, enabling flexible multi-supply circuit configurations. An inverting amplifier accepts a positive input voltage and inverts it to a negative voltage of equal magnitude, and likewise inverts a negative input voltage to a positive voltage.
