1 / 31 page LMP2232 www.ti.com SNOSB02C – JANUARY 2008 – REVISED MARCH 2013 LMP2232 Dual Micropower, 1.6V, Precision, Operational Amplifier with CMOS Input Check for Samples: LMP2232 1 FEATURES DESCRIPTION The LMP2232 is a dual micropower precision 23 (For VS = 5V, Typical Unless Otherwise Noted) amplifier designed for battery powered applications. • Supply Current at 1.8V 16 µA The 1.6V to 5.5V operating supply voltage range and • Operating Voltage Range 1.6V to 5.5V quiescent power consumption of only 26 μW extend the battery life in portable systems. The LMP2232 is • Low TCVOS ±0.5 µV/°C (max) part of the LMP™ precision amplifier family. The high • VOS ±150 µV (max) impedance CMOS input makes it ideal for • Input Bias Current 20 fA instrumentation and other sensor interface applications. • PSRR 120 dB • CMRR 97 dB The LMP2232 has a maximum offset voltage of 150 μV and maximum offset voltage drift of only 0.5 μV/°C • Open Loop Gain 120 dB along with low bias current of only ±20 fA. These • Gain Bandwidth Product 130 kHz precise specifications make the LMP2232 a great • Slew Rate 58 V/ms choice for maintaining system accuracy and long term stability. • Input Voltage Noise, f = 1 kHz 60 nV/ √Hz • Temperature Range –40°C to 125°C The LMP2232 has a rail-to-rail output that swings 15 mV from the supply voltage, which increases system dynamic range. The common mode input voltage APPLICATIONS range extends 200 mV below the negative supply, • Precision Instrumentation Amplifiers thus the LMP2232 is ideal for ground sensing in • Battery Powered Medical Instrumentation single supply applications. • High Impedance Sensors The LMP2232 is offered in 8-pin SOIC and VSSOP • Strain Gauge Bridge Amplifier packages. • Thermocouple Amplifiers The LMP2231 is the single version of this product and the LMP2234 is the quad version of this product. Both of these products are available on Texas Instruments' website. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 LMP is a trademark of Texas Instruments. 3 All other trademarks are the property of their respective owners.
