LMP7711 Precision, 17 MHz, Low Noise, CMOS Input Amplifier PRELIMINARY September 2005 LMP7711 Precision, 17 MHz, Low Noise, CMOS Input Amplifier General Description The LMP7711 is a low noise, low offset, CMOS input, railto-rail output precision amplifier with a high gain bandwidth and an enable pin. The LMP7711 is part of the LMP™ precision amplifier family and is ideal for a variety of instrumentation applications. Utilizing a CMOS input stage, the LMP7711 achieves an input bias current of 100 fA, input referred voltage noise of , and an input offset voltage of less than 5.8 nV/ ± 150 µV. These features make the LMP7711 a superior choice for precision applications. Consuming only 1.15 mA of supply current, the LMP7711 offers a high gain bandwidth of 17 MHz, enabling accurate amplification at high closed loop gains. The LMP7711 has a supply voltage range of 1.8V to 5.5V; which makes this an ideal choice for portable low power applications with low supply voltage requirements. In order to reduce the already low power consumption of the LMP7711, an enable function is available. Once in shutdown, the LMP7711 draws only 140 nA of supply current. The LMP7711 is built with National’s advanced VIP50 process technology. The LMP7711 is available in a 6-pin TSOT23 package.

Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics Tables. Note 2: Human Body Model: 1.5 kΩ in series with 100 pF. Machine Model: 0Ω in series with 200 pF. Note 3: The maximum power dissipation is a function of TJ(MAX), θJA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX) - TA)/θJA. All numbers apply for packages soldered directly onto a PC Board. Note 4: Typical values represent the most likely parametric norm at the time of characterization. Note 5: Limits are 100% production tested at 25˚C. Limits over the operating temperature range are guaranteed through correlations using the Statistical Quality Control (SQC) method. Note 6: Offset voltage average drift is determined by dividing the change in VOS at the temperature extremes by the total temperature change. Note 7: Positive current corresponds to current flowing into the device. Note 8: Guaranteed by design. Note 9: The short circuit test is a momentary test.
