September 2005 LMV651 12 MHz, Low Voltage, Low Power Amplifier General Description Features National’s LMV651 is a high performance, low power op amp IC implemented in National’s advanced VIP50 process. The unity gain stable LMV651 features 12 MHz of bandwidth while consuming only 110 uA of current, an exceptional bandwidth to power ratio in this op amp class, and maintains stability for capacitive loads as large as 500 pF. (Typical 5V supply, unless otherwise noted) n Guaranteed 3.0V and 5.0V performance n High unity gain bandwidth 12 MHz n Low power supply current 110 µA n Max input offset voltage 1 mV n Capacitive load drive capability 500 pF n CMRR 100 dB n PSRR 95 dB n Input referred voltage noise 17nV/ n Output swing with 2 kΩ load 50 mV from rail n Total harmonic distortion 0.003% @ 1 kHz, 600Ω n Temperature range −40˚C to 125˚C The LMV651 provides superior performance and economy in terms of power and space usage. The LMV651 has a maximum input offset voltage of 1 mV, a rail to rail output stage and an input common-mode voltage range that includes ground. The LMV651 provides a PSRR of 95 dB, a CMRR of 100 dB and a total harmonic distortion (THD) of 0.003% at 1 kHz frequency and 600Ω load The LMV651 has an operating supply voltage range from 2.7V to 5.5V. The LMV651 can operate over a wide temperature range (-40˚C to +125˚C) making the op amp ideal for automotive applications, sensor applications and portable equipment applications. The LMV651 is available in the ultra tiny SC70-5 package, which is about half the size of the SOT23-5.

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, and TA. 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 Statistical Quality Control (SQC) method. Note 6: Positive current corresponds to current flowing into the device. Note 7: Slew rate is the average of the rising and falling slew rates. Note 8: Short circuit test is a momentary test. 3 www.national.com LMV651 5V DC Electrical Characteristics LMV651 Connection Diagram 5-Pin SC70/SOT23 20123802 Top View Ordering Information Package 5-Pin SC70 Part Number Package marking LMV651MG A93 LMV651MGX www.national.com Transport Media NSC Drawing 1k Units Tape and Reel MA005A 3 k Units Tape and Reel 4 LMV651 12 MHz, Low Voltage, Low Power Amplifier Physical Dimensions inches (millimeters) unless otherwise noted 5-Pin SC70 NS Package Number MAA05A National does not assume any responsibility for use of any circuitry described, no circuit patent licenses are implied and National reserves the right at any time without notice to change said circuitry and specifications.
