Product details

Overview

LMV722MX/NOPB from Texas Instruments is a dual, rail-to-rail output, low-noise (9 nV/√Hz), low-voltage (2.2 V to 5.5 V), and low-power (1.81 mA/amplifier at 2.2 V) operational amplifier optimized for battery-powered signal conditioning. It delivers 10 MHz unity-gain bandwidth, 5.25 V/µs slew rate at 5 V, and 120 mV rail-to-rail swing into 600 Ω - enabling high-fidelity audio preamplification in portable electronics.

For engineers reviewing the LMV722MX/NOPB datasheet, LMV722MX/NOPB pinout, LMV722MX/NOPB application, or LMV722MX/NOPB equivalent, key selection criteria include its guaranteed 2.2 V operation, input common-mode range extending to ground, 3.5 mV max input offset voltage over temperature, and SOIC-8 package compatibility with space-constrained industrial and consumer PCB layouts.

Technical Context

The LMV722MX/NOPB employs a bipolar input stage with BiCMOS process technology, supporting single-supply operation down to 2.2 V while maintaining rail-to-rail output swing and input common-mode voltage range that includes ground. Its 10 MHz gain-bandwidth product and 67–72° phase margin ensure stable unity-gain buffer and active filter configurations.

It exhibits low input bias current (260 nA typical), low input voltage noise (8.5–9 nV/√Hz), and robust capacitive load tolerance (4700 pF stable in unity-gain). The device operates across −40°C to +85°C and is rated for 6 V absolute maximum supply voltage.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.2 V to 5.5 V - enables full functionality across depleted lithium coin-cell and regulated 3.3 V rails.
Unity-Gain Bandwidth	10 MHz - supports audio bandwidth (20 Hz–20 kHz) with >500× gain margin for stable filtering.
Slew Rate	5.25 V/µs at 5 V - ensures <1% THD for 1 V_PP signals up to ~800 kHz in buffer applications.
Input Voltage Noise	8.5 nV/√Hz at 1 kHz - critical for low-level microphone and sensor signal amplification without added noise floor.
Rail-to-Rail Output Swing	120 mV from either rail into 600 Ω at 2.2 V - maximizes dynamic range in low-voltage systems.
Input Offset Voltage	3.5 mV max over temperature - limits DC error in precision DC-coupled gain stages and instrumentation front-ends.
Quiescent Current	1.81 mA per amplifier at 2.2 V - extends battery life in always-on portable sensing nodes.

Pinout & Package

LMV722MX/NOPB is housed in an 8-pin SOIC (Package D, JEDEC MS-012) with 1.27 mm pitch, 4.9 mm × 3.9 mm body, and 1.75 mm height. Pin 1 is marked by a beveled corner or notch on the package top edge.

Pin/Terminal	Circuit Role	Design Meaning
1	Inverting Input (Amplifier A)	Accepts feedback network input; requires matched impedance to non-inverting input to minimize bias-current-induced offset.
2	Non-Inverting Input (Amplifier A)	Reference node for A-channel gain setting; supports ground-referenced inputs in single-supply configurations.
3	Output (Amplifier A)	Delivers rail-to-rail voltage swing; capable of sourcing 52.6 mA and sinking 23.7 mA at 5 V supply.
4	V− (Ground / Negative Supply)	Reference return for both amplifiers; must be low-impedance to maintain PSRR >70 dB and prevent ground bounce.
5	Non-Inverting Input (Amplifier B)	Independent input for second channel; shares same supply and ground connections as Channel A.
6	Inverting Input (Amplifier B)	Second channel feedback node; layout symmetry with Pin 1 recommended to reduce crosstalk.
7	Output (Amplifier B)	Independent output; supports separate load networks; stable driving 4700 pF directly in unity-gain.
8	V+ (Positive Supply)	Power input for both amplifiers; requires local 100 nF ceramic decoupling to ground within 5 mm.

Key Features

Feature	Design Value
Rail-to-rail output swing into 600 Ω	Enables full utilization of 2.2 V supply range - delivers 2.065 V_MAX/0.145 V_MIN output swing at 2.2 V, preserving SNR in low-voltage audio paths.
Input common-mode voltage range includes ground	Allows direct sensing of 0 V referenced signals (e.g., electret mic bias, thermistor dividers) without level-shifting circuitry.
Guaranteed 2.2 V and 5.0 V performance	Ensures consistent gain, bandwidth, and noise specs across full battery discharge curve - no derating required below 3 V.
Low input voltage noise (9 nV/√Hz @ 1 kHz)	Minimizes contribution to system noise floor in microphone preamps and precision sensor interfaces where source impedances are <10 kΩ.
Capacitive load drive capability (4700 pF)	Eliminates need for isolation resistors when driving ADC input capacitance or long PCB traces - simplifies layout and reduces component count.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual low-voltage operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LMV722MM/NOPB	VSSOP-8 package (3.0 mm × 3.0 mm), 235°C/W θ_JA, identical electrical specs.	Preferred for ultra-dense layouts where SOIC footprint is prohibitive; requires finer-pitch assembly.	Select when board space is constrained and reflow profile supports VSSOP handling.
TLV272IDR	Lower quiescent current (1.3 mA vs. 1.81 mA), lower GBW (3 MHz), higher V_OS (5 mV max), same SOIC-8.	Better suited for ultra-low-power wake-up circuits; insufficient bandwidth for audio or fast-filter applications.	Choose only if bandwidth <3 MHz and noise >20 nV/√Hz are acceptable trade-offs for extended battery life.

Compared with LMV722MM/NOPB, LMV722MX/NOPB offers identical performance in a larger, more manufacturable SOIC package with better thermal dissipation (190°C/W vs. 235°C/W); versus TLV272IDR, it delivers 3.3× higher bandwidth and 2.2× lower noise at the cost of +0.5 mA supply current - making it optimal for audio and precision-sensing roles where speed and fidelity are prioritized.

FAQ

What is the minimum supply voltage for reliable operation of the LMV722MX/NOPB?

The LMV722MX/NOPB is specified for guaranteed operation down to 2.2 V across the full −40°C to +85°C temperature range. At this voltage, it maintains 10 MHz unity-gain bandwidth, 930 µA per amplifier quiescent current, and rail-to-rail output swing into 600 Ω. Operation below 2.2 V is not characterized and may result in degraded gain, bandwidth, or output swing. The LMV722MX/NOPB datasheet explicitly confirms 2.2 V as the lower limit of the operating ratings.

Does the LMV722MX/NOPB support rail-to-rail input operation?

No, the LMV722MX/NOPB does not support rail-to-rail input operation. Its input common-mode voltage range extends to ground (−0.3 V min) but only up to 1.3 V at 2.2 V supply and 4.1 V at 5 V supply - meaning the input cannot swing to the positive rail. However, the input range *includes ground*, enabling true single-supply operation with grounded sensors. The LMV722MX/NOPB output is rail-to-rail, but input headroom above V− is limited; exceeding the specified V_CM range degrades CMRR and may cause phase reversal.

Can the LMV722MX/NOPB drive heavy capacitive loads without external compensation?

Yes, the LMV722MX/NOPB is characterized to drive up to 4700 pF directly in unity-gain configuration without oscillation - making it suitable for driving ADC input capacitance, long cables, or large bypass networks. This stability is achieved via internal compensation optimized for low-voltage operation. For loads exceeding 4700 pF or in high-gain configurations, external isolation (e.g., series resistor at output) is recommended. The LMV722MX/NOPB datasheet confirms this 4700 pF rating in the "Capacitive Load Tolerance" application note.

What is the maximum output current capability of the LMV722MX/NOPB at 5 V supply?

At 5 V supply, the LMV722MX/NOPB can source up to 52.6 mA and sink up to 23.7 mA while maintaining specified performance, as measured under V_IN(diff) = ±0.5 V conditions. These values represent short-term peak currents; continuous operation above 30 mA may elevate junction temperature beyond safe limits depending on PCB thermal design. The LMV722MX/NOPB thermal resistance (θ_JA) is 190°C/W for the SOIC-8 package, so sustained high-current operation requires adequate copper pour and airflow.

Is the LMV722MX/NOPB pin-compatible with other dual op-amps in SOIC-8 packages?

The LMV722MX/NOPB follows the standard SOIC-8 pinout for dual op-amps (Pin 1: A−, Pin 2: A+, Pin 3: AOUT, Pin 4: V−, Pin 5: B+, Pin 6: B−, Pin 7: BOUT, Pin 8: V+), matching industry conventions used by TL072, LM358, and TLV272. However, electrical characteristics - especially input stage type (bipolar vs. CMOS), noise, bandwidth, and supply range - differ significantly. While physical pinout is compatible, direct substitution requires verification of V_OS, I_B, GBW, and supply requirements. The LMV722MX/NOPB is not a drop-in replacement for all SOIC-8 dual op-amps.
