The LMP7731 is a single, low noise, rail-to-rail input and output, low voltage amplifier. The LMP7731 is part of the LMP precision amplifier family and is ideal for precision and low noise applications with low voltage requirements. This operational amplifier offers low voltage noise of 2.9 nV/√Hz with a 1/f corner of only 3 Hz. The LMP7731 has bipolar input stages with a bias current of only 1.5 nA. This low input bias current, complemented by the very low level of voltage noise, makes the LMP7731 an excellent choice for photometry applications. The LMP7731 provides a wide GBW of 22 MHz while consuming only 2 mA of current. This high gain bandwidth along with the high open loop gain of 130 dB enables accurate signal conditioning in applications with high closed loop gain requirements. The LMP7731 has a supply voltage range of 1.8V to 5.5V, making it an ideal choice for battery operated portable applications. The LMP7731 is offered in the space saving 5-Pin SOT-23 and 8-Pin SOIC packages. The LMP7731 is a single, low noise, rail-to-rail input and output, low voltage amplifier.

The LMP8278 is a fixed 14x gain precision current sense amplifier. The part amplifies and filters small differential signals in the presence of high common mode voltages. The part operates from a single 5V supply voltage. With an input common mode voltage range from -2V to +28V the gain is very precise (±0.5%). The part can handle common mode voltages in the range -2V to +40V with relaxed specifications. The LMP8278 is a member of the Linear Monolithic Precision (LMP) family and is ideal for unidirectional current sensing applications. The parameter values that are shown in the Electrical Characteristics table are 100% tested and all bold values are also 100% tested over temperature, unless otherwise noted. The part has a precise gain of 14x which is adequate in most targeted applications to drive an ADC to its full scale value. The fixed gain is achieved in two separate stages, a preamplifier with a gain of 7x and an output stage buffer amplifier with a gain of 2x. The connection between the two stages of the signal path is brought out on two pins to enable the possibility to create an additional filter network around the output buffer amplifier. These pins can also be used for alternative configurations with different gain as described in . The LMP8278Q incorporates enhanced manufacturing and support processes for the automotive market, including defect detection methodologies. Reliability qualification is compliant with the requirements and temperature grades defined in the AEC Q100 standard. The LMP8278 is a fixed 14x gain precision current sense amplifier.
