Product details
Overview
LMV712MMX/NOPB 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 LMV712MMX/NOPB datasheet, LMV712MMX/NOPB pinout, LMV712MMX/NOPB application, or LMV712MMX/NOPB 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 operation across –40°C to 85°C.
Technical Context
The LMV712MMX/NOPB uses parallel NMOS and PMOS input stages with internal logic to maintain stable rail-to-rail input operation across the full common-mode range (–0.2 V to V+ + 0.3 V). Its folded cascode architecture provides 5 MHz unity-gain bandwidth while supporting 200 pF capacitive loads without oscillation.
Each amplifier features an independent shutdown pin that reduces supply current to ≤1.5 µA and forces output to V− during disable. Turnon is glitch-free with smooth ramping, critical for RF power amplifier bias control where output transients must avoid disrupting transmission integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 5 MHz - supports stable unity-gain buffer and closed-loop configurations up to ~100 kHz with phase margin ≥60° |
| Slew rate | 5 V/µs - enables clean 100 kHz sine wave reproduction with <1% distortion at 2 Vpp output |
| Input voltage noise | 20 nV/√Hz at 1 kHz - suitable for low-level sensor signal amplification without significant noise contribution |
| Supply current per channel | 1.22 mA typical at 2.7 V - allows dual-channel operation on coin-cell or single Li-ion battery for >100 hours |
| Input offset voltage | ≤3 mV max - ensures ≤0.3% error in 1 V full-scale analog front-end applications |
| Rail-to-rail output swing | Within 12 mV of V+ and V− at 10 kΩ load - preserves dynamic range in single-supply 2.7 V systems |
| Shutdown current | ≤1.5 µA per channel - reduces total system standby power to sub-µW levels when unused |
Pinout & Package
The LMV712MMX/NOPB is packaged in a 10-pin VSSOP (DGS) with 3.0 mm × 3.0 mm body size and 0.5 mm pitch. Pin 1 is OUT A; pin 4 is V−; pin 5 is SD A; pin 6 is SD B; pin 10 is V+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Drives external load directly; rail-to-rail swing supports full 2.7 V supply utilization |
| 2 (–IN A) | Channel A inverting input | Accepts feedback network connection; high impedance (>10¹² Ω) minimizes loading on source |
| 3 (+IN A) | Channel A noninverting input | Receives input signal or reference; common-mode range extends 0.2 V below V− and 0.3 V above V+ |
| 4 (V−) | Negative supply | Ground reference for single-supply operation; thermal pad (pin 11) must be connected to V− for optimal thermal performance |
| 5 (SD A) | Channel A shutdown control | Logic-low (<0.8 V) disables Channel A; output defaults to V− with <200 mV residual voltage |
| 6 (SD B) | Channel B shutdown control | Independent of SD A; enables selective power gating for multi-function analog subsystems |
| 7 (+IN B) | Channel B noninverting input | Dedicated second channel input; electrically isolated from Channel A for differential or dual-path processing |
| 8 (–IN B) | Channel B inverting input | Supports separate feedback loop; no crosstalk with Channel A inputs per datasheet characterization |
| 9 (OUT B) | Channel B output | Provides matched performance to OUT A; identical GBW, slew rate, and noise specs |
| 10 (V+) | Positive supply | Accepts 2.7–5.5 V; PSRR ≥70 dB ensures immunity to supply ripple in noisy RF environments |
Key Features
| Feature | Design Value |
|---|---|
| Independent dual shutdown | Enables per-channel power gating in battery-powered systems, reducing idle current to <3 µA total |
| Glitch-free turnon | 2.2 µs ramp time prevents transient injection into RF PA bias lines, avoiding TX spectral regrowth |
| Rail-to-rail I/O | Supports full-scale signal handling in 2.7 V single-supply designs without level-shifting circuitry |
| 200 pF capacitive load drive | Eliminates need for external isolation resistors in PCB trace or filter capacitor interfaces |
| Low 20 nV/√Hz noise | Maintains SNR >86 dB in 10 kHz bandwidth applications such as baseband signal conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power RRIO operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2782IDR | Lower 1.8 V min supply; 3.8 MHz GBW; no independent shutdown pins - single global shutdown only | Not suitable for per-channel power gating; requires redesign of control logic for PA bias sequencing | Select when operating below 2.7 V or when global shutdown suffices and cost is primary constraint |
| OPA2314AIDR | Higher 3.8 V/µs slew rate; 3.6 MHz GBW; 1.1 mA/channel supply; no shutdown feature | Lacks shutdown capability - unsuitable for burst-mode RF systems requiring rapid channel enable/disable | Select when ultra-low quiescent current (1.1 mA) is critical and shutdown functionality is implemented externally |
Compared with TLV2782IDR and OPA2314AIDR, the LMV712MMX/NOPB uniquely combines independent shutdown, 5 MHz bandwidth, and rail-to-rail I/O in a 10-pin VSSOP package - making it the only option for space-constrained, battery-powered RF control loops requiring glitch-free channel activation.

FAQ
What is the maximum capacitive load the LMV712MMX/NOPB can drive without external compensation?
The LMV712MMX/NOPB can directly drive up to 200 pF in unity-gain configuration without oscillation, as verified in TI's datasheet Figure 17 and Section 7.4.2. This eliminates the need for isolation resistors in typical PCB trace or filter capacitor interfaces, simplifying layout in compact RF modules.
Does the LMV712MMX/NOPB support true rail-to-rail input at 2.7 V supply?
Yes, the LMV712MMX/NOPB supports rail-to-rail input with common-mode voltage range from (V− − 0.2 V) to (V+ + 0.3 V) at 2.7 V supply, per Section 6.5 CMVR specification. This enables direct interfacing with sensors or DACs operating near supply rails without level-shifting circuitry.
What is the typical turnon time from shutdown for the LMV712MMX/NOPB at 25°C?
The LMV712MMX/NOPB has a typical turnon time of 2.2 µs from shutdown at 25°C under 2.7 V supply, as specified in Section 6.5 TON. This fast, glitch-free ramp ensures clean activation in GSM TDMA slot timing-critical applications.
How does the LMV712MMX/NOPB handle input offset voltage variation over common-mode voltage?
The LMV712MMX/NOPB exhibits a crossover point in input offset voltage near 1.4 V above V− (Figure 3), due to its dual-input-stage architecture. Designers must avoid this region in high-accuracy applications or use trimming techniques, as VOS can reach up to 9 mV in DSBGA variants at temperature extremes.
Is the LMV712MMX/NOPB pin-compatible with other TI dual op-amps in VSSOP-10 packages?
No, the LMV712MMX/NOPB has a unique pinout optimized for independent shutdown (pins 5 and 6), differing from standard dual op-amps like TLV2782IDR (no shutdown) or OPA2314AIDR (no shutdown). PCB layout must follow the DGS package pin map in Section 5 of the datasheet.
