LMP7701/2 Precision Amplifiers

Texas Instruments offers CMOS input, RRIO, wide supply range amplifiers

image of Texas Instruments' LMP7312 Precision Amplifier attenuator Texas Instruments' single and dual low offset voltage, rail-to-rail input and output precision amplifiers each have a CMOS input stage and a wide supply voltage range. They're part of the LMP® precision amplifier family and are ideal for sensor interface and other instrumentation applications. The guaranteed low offset voltage of less than ±200 µV along with the guaranteed low input bias current of less than ±1 pA make the LMP7701 ideal for precision applications. The LMP7701 and LMP7702 are built utilizing VIP50 technology, which allows the combination of a CMOS input stage and a 12 V common mode and supply voltage range. This makes the LMP7701 and LMP7702 great choices in many applications where conventional CMOS parts cannot operate under the desired voltage conditions.
