Texas Instruments LMP8671 single and LMP8672 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 LMP8671 and LMP8672 precision amplifiers allows them to be used over a wide frequency without degradation. TI LMP8671 and LMP8672 precision amplifiers offer an extremely high open loop gain of 135dB, low voltage noise density (2.5nV/√Hz), and a 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 LMP8671 and 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.
