Texas Instruments LMP8672 Low Noise Precision Amplifiers

Texas InstrumentsLMP8672 Dual 40V Low Noise Precision Amplifiers combine great precision, low noise, and a wide operating voltage range to provide a high SNR and a wide dynamic range. The AC performance of LMP8672 precision amplifiers allows them to be used over a wide frequency without degradation. LMP8672 precision amplifiers offer an extremely high open-loop gain of 135dB, low voltage noise density (2.5nV/√Hz), and superb linearity of 0.000009%. These TI precision amplifiers also feature a high slew rate of ±20V/µs and an output current capability of ±26mA. The Texas Instruments LMP8672 are ideal for use in applications requiring DC precision and low noise, such as precision PLL filters, multi-feedback, and multi-pole active filters, GPS receivers, and precision control loop systems.
