LMP2231 is a single, low-power, high-precision amplifier designed for battery-powered applications. The operating power supply voltage range from 1.6V to 5.5V and the static power consumption of only 16μW extend battery life in portable battery-powered systems. LMP2231 is part of the LMP high-precision amplifier series. High-impedance CMOS input, ideal choice for instrument and other sensor interface applications.
LMP2231 has a maximum ± of 150 μV and a maximum offset voltage drift of only 0.4 μV/°C to offset the low bias current of only 20 FA. These precise specifications make LMP2231 a great choice for maintaining system accuracy and long-term stability.
LMP2231 has a rail-to-rail output swing from the supply voltage, which increases the dynamic range of the system to 15 mV. The common mode input voltage range is extended by 200 millivolts below the negative supply, making it ideal for use in single LMP2231-supply applications and with ground remote sensing.
LMP2231 is available in a 5-pin SOT23 package and an 8-pin SOIC package.
Dual and quad versions of this product are also available. Dual, LMP2232 provide 8-pin SOIC and MSOP. Four, LMP2234 offers 14-pin SOIC and TSSOP.
