Product details
Overview
LMV712MM-TI from Texas Instruments is a dual rail-to-rail input/output operational amplifier with independent shutdown control, designed for low-voltage portable systems. It delivers 5 MHz gain-bandwidth, 5 V/µs slew rate, 20 nV/√Hz input voltage noise, 1.22 mA/channel supply current, and operates from 2.7 V to 5.5 V - enabling precision signal conditioning in GSM power amplifier control loops.
For engineers reviewing the LMV712MM-TI datasheet, LMV712MM-TI pinout, LMV712MM-TI application, or LMV712MM-TI equivalent, key selection criteria include independent channel shutdown timing (2.2 µs turnon), rail-to-rail output swing within 12 mV of rails at 10 kΩ load, low input offset voltage (≤3 mV), capacitive load tolerance up to 200 pF, and AEC-Q100 Grade 1 qualification for automotive-grade reliability.
Technical Context
The LMV712MM-TI employs parallel NMOS and PMOS input stages with dynamic bias switching to achieve rail-to-rail input operation across –0.3 V to V+ + 0.3 V common-mode range. Its folded-cascode gain stage and Class AB output stage deliver stable unity-gain performance with ≥60° phase margin.
Independent SDA and SDB pins enable per-channel shutdown, reducing supply current to ≤1.5 µA per channel while holding outputs near V–. The device maintains full functionality over –40°C to 125°C (Q1 variant) and supports single-supply operation down to 2.7 V with guaranteed 2.7-V and 5-V specifications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 5 MHz - enables stable closed-loop operation up to 100 kHz with gain ≥50 in sensor interface or PA control feedback paths |
| Slew rate | 5 V/µs - supports fast transient response in RF power amplifier envelope tracking without distortion |
| Input voltage noise | 20 nV/√Hz at 1 kHz - preserves SNR in low-level analog signal conditioning for detector circuits |
| Supply current per channel | 1.22 mA typical at 2.7 V - allows dual-opamp implementation in battery-powered handheld devices with <2.5 mA total quiescent draw |
| Shutdown current | 1.5 µA max per channel - extends battery life during idle periods in time-multiplexed RF subsystems |
| Output swing | Rail-to-rail: within 12 mV of V+ and V– at 10 kΩ load - maximizes dynamic range in single-supply 3.3 V or 5 V systems |
| Common-mode range | –0.3 V to V+ + 0.3 V - accommodates input signals extending beyond supply rails in DC-coupled detector interfaces |
Pinout & Package
LMV712MM-TI is packaged in a 10-pin VSSOP (DGS) with 3.0 mm × 3.0 mm body size and 0.5 mm lead pitch. Pin 1 is OUTA; pin 4 is V–; pin 5 is SDA; pin 6 is SDB; pin 10 is V+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTA) | Channel A output | Drives external load or feedback network; rail-to-rail swing supports full-scale DAC output buffering |
| 2 (–INA) | Channel A inverting input | Accepts feedback signal in transimpedance or inverting amplifier configurations for current-sense applications |
| 3 (+INA) | Channel A noninverting input | Receives reference or sensor signal; high-impedance input minimizes loading on precision voltage dividers |
| 4 (V–) | Negative supply | Ground reference for single-supply operation; thermal pad connection point in DSBGA/WSON variants |
| 5 (SDA) | Channel A shutdown | Active-low control: pulls low to disable Channel A, reducing ICC to <1.5 µA and forcing OUTA to V– |
| 6 (SDB) | Channel B shutdown | Independent active-low control for Channel B - enables time-gated dual-channel operation in TDD systems |
| 7 (+INB) | Channel B noninverting input | Supports dual-path signal processing, e.g., differential detection or redundant control loop monitoring |
| 8 (–INB) | Channel B inverting input | Enables matched dual-channel configuration for balanced RF front-end biasing or calibration circuitry |
| 9 (OUTB) | Channel B output | Provides second independent output for auxiliary functions such as temperature-compensated bias generation |
| 10 (V+) | Positive supply | Accepts 2.7–5.5 V; internal regulation ensures consistent performance across Li-ion battery discharge curve |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2782IDR | Lower GBW (2.5 MHz), no shutdown pins, higher supply current (1.6 mA/channel) | Lacks independent shutdown; unsuitable for TDD or burst-mode PA control | Select when cost sensitivity outweighs need for shutdown control and higher speed |
| OPA2333AIDR | Zero-drift architecture, lower offset (2 µV), higher supply current (17 µA/channel), no shutdown | Superior DC accuracy but no power-gating capability; slower turnon invalidates glitch-free PA ramping | Select for precision DC-coupled sensor front-ends where shutdown is unnecessary |
Compared with TLV2782IDR and OPA2333AIDR, LMV712MM-TI uniquely combines 5 MHz bandwidth, independent shutdown, and 2.2 µs glitch-free turnon - making it the only option qualified for GSM PA control loops requiring dynamic power gating and spectral purity.

FAQ
What is the maximum capacitive load the LMV712MM-TI can drive without external compensation?
The LMV712MM-TI can directly drive up to 200 pF in unity-gain configuration without oscillation or instability. This capability eliminates the need for isolation resistors when interfacing with RF detector diodes, PCB trace capacitance, or small ceramic decoupling caps. Exceeding 200 pF requires external RISO compensation per Figure 32 in the LMV712MM-TI datasheet to maintain ≥60° phase margin.
Does the LMV712MM-TI support true rail-to-rail input operation across the full supply range?
Yes, the LMV712MM-TI supports rail-to-rail input operation from V– – 0.3 V to V+ + 0.3 V, verified across –40°C to 125°C. Its dual-input-stage architecture (NMOS + PMOS pairs) dynamically selects active input transistors based on common-mode voltage, ensuring continuous operation and low distortion even when inputs approach or slightly exceed supply rails - critical for DC-coupled detector interfaces.
How does the shutdown function behave on the LMV712MM-TI during power-up sequences?
During power-up, the LMV712MM-TI requires explicit logic-level assertion on SDA/SDB pins to enable channels - they must not be left floating due to leakage-induced false shutdown. When enabled, Channel A and B enter active mode with 2.2 µs glitch-free output ramp. In shutdown, each channel draws ≤1.5 µA and forces its output to V–, preventing unintended bias injection into downstream RF stages.
Is the LMV712MM-TI qualified for automotive applications?
Yes, the LMV712MM-TI is available in an AEC-Q100 Grade 1 qualified variant (LMV712-N-Q1), rated for operation from –40°C to +125°C ambient temperature. This qualification covers thermal cycling, humidity testing, and ESD robustness per automotive standards - making it suitable for infotainment head units, telematics control units, and ADAS sensor signal conditioning modules.
What is the typical input offset voltage specification for the LMV712MM-TI at 25°C and 5 V supply?
The LMV712MM-TI has a typical input offset voltage of 0.4 mV and a maximum of 3 mV at 25°C and 5 V supply, as specified in the WSON and VSSOP package variants. This low VOS ensures minimal DC error in precision closed-loop applications such as RF power detector linearization and battery voltage monitoring circuits.
