LMP8671, LMP8672, LMP8674 www.ti.com SNOSB39B – JULY 2011 – REVISED MARCH 2013 Single, Dual, and Quad 40V Low Noise Precision Amplifiers Check for Samples: LMP8671, LMP8672, LMP8674 FEATURES DESCRIPTION • • • The LMP8671/2/4 combines great precision, low noise and a large operating voltage range to provide a high SNR and a wide dynamic range. Its AC performance allows it to be used over a wide frequency without degradation. It is the ideal choice for 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. The LMP8671/2/4 offers an extremely high open loop gain of 135dB, low voltage noise density (2.5nV/√Hz), and a superb linearity of 0.000009%. These characteristics drastically reduce gain error which is a challenge in accurate systems requiring higher gains such as data acquisition systems. 1 2 Output Short Circuit Protection PSRR and CMRR Exceed 110dB Best in Class Linearity (135dB) APPLICATIONS • • • • • Low Noise Industrial Applications Including Test, Measurement, and Ultrasound Precision Active Filters PLL Filters 4-20mA Current Loops Motor Control KEY SPECIFICATIONS • • • • • • • • Input Offset Voltage 0.4mV TC VOS 2μV/°C (max) Power Supply Voltage Range ±2.5V to ±20V Voltage Noise Density 2.5nV/√Hz Slew Rate ±20V/μs Gain Bandwidth Product 55MHz Open Loop Gain 135dB Input Bias Current 10nA To ensure that the most challenging loads are driven without compromise, the LMP8671/2/4 has a high slew rate of ±20V/μs and an output current capability of ±26mA. The LMP8671/2 family of high-voltage amplifiers are available in SOIC-8, the LMP8674 in SOIC-14. Connection Diagrams NC -IN +IN V- NC - V+ + VOUT NC Figure 1. See Package Number — D0008A Figure 2.

Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or other conditions beyond those indicated in the Recommended Operating Conditions is not implied. The Recommended Operating Conditions indicate conditions at which the device is functional and the device should not be operated beyond such conditions. All voltages are measured with respect to the ground pin, unless otherwise specified. The Electrical Characteristics tables list ensured specifications under the listed Recommended Operating Conditions except as otherwise modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are not ensured. If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications. The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX, θJA, and the ambient temperature, TA. The maximum allowable power dissipation is PDMAX = (TJMAX - TA) / θJA or the number given in Absolute Maximum Ratings, whichever is lower. Human body model, applicable std. JESD22-A114C.
