Product details
Overview
LMV711M6X/NOPB from Texas Instruments is a rail-to-rail input/output, low-power operational amplifier with shutdown control, 5 MHz gain-bandwidth product, 5 V/µs slew rate, and 3 mV max input offset voltage - designed for battery-powered RF power control and AGC circuits in wireless handsets.
For engineers reviewing the LMV711M6X/NOPB datasheet, LMV711M6X/NOPB pinout, LMV711M6X/NOPB application, or LMV711M6X/NOPB equivalent, this device delivers high-output-current drive (±28 mA), sub-10 µs turnon from shutdown, and stable operation driving 600-Ω loads across 2.7–5 V supply - critical for GSM/CDMA power amp biasing and Bluetooth front-end signal conditioning.
Technical Context
The LMV711M6X/NOPB uses a BiCMOS process with paralleled PMOS/NMOS input stages to achieve rail-to-rail input common-mode range extending 300 mV beyond rails, while maintaining CMRR ≥45 dB over −40°C to 85°C. Its Class AB output stage delivers ±28 mA sourcing/sinking capability into resistive loads.
Shutdown is controlled by an active-low SD pin; when asserted, supply current drops to 0.2 µA (typ), output settles to ~50 mV above V−, and turnon time is <10 µs. The device is unity-gain stable and supports capacitive loads up to 200 pF directly in follower configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 5 MHz - enables stable closed-loop operation up to 100 kHz at gain = 50, suitable for AGC loop filters and RF detector bandwidths. |
| Slew rate | 5 V/µs - supports fast transient response in power amplifier bias control without distortion on 1–2 Vpp envelope signals. |
| Input offset voltage (max) | 3 mV - ensures ≤0.3% error in 1-V full-scale current-sense applications using 100-mΩ shunts. |
| Supply current (ON mode) | 1.7 mA (typ) at 2.7 V - extends battery life in portable devices operating >100 hours on coin-cell or Li-ion sources. |
| Output drive (600 Ω) | Rail-to-rail swing within 100 mV of rails at 2.7 V - maintains >95% dynamic range for baseband I/Q signal buffering. |
| Shutdown current | 0.2 µA (typ) - reduces quiescent load to negligible level during idle periods in TDMA burst-mode systems. |
| Common-mode range | V− −0.3 V to V+ +0.3 V - allows direct sensing of high-side currents referenced to battery voltage without level-shifting. |
Pinout & Package
LMV711M6X/NOPB is housed in a 6-pin SOT-23 package (2.92 mm × 1.50 mm body size) with gull-wing leads, optimized for space-constrained RF modules and handheld PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Delivers rail-to-rail voltage swing; capable of ±28 mA continuous drive into 600 Ω; remains at ~50 mV above V− in shutdown. |
| 2 - V− | Negative supply | Ground reference for single-supply operation; must be connected directly to PCB ground plane for noise immunity. |
| 3 - IN+ | Noninverting input | High-impedance CMOS node (4 pA bias current); accepts signals from V− −0.3 V to V+ +0.3 V without phase reversal. |
| 4 - IN− | Inverting input | Differential input node; used with feedback network to set gain and bandwidth; sensitive to layout parasitics above 1 MHz. |
| 5 - SD | Shutdown enable | Active-low digital control input; must be tied to V+ if unused to prevent oscillation; pulls supply current to 0.2 µA when low. |
| 6 - V+ | Positive supply | Accepts 2.7–5 V DC; requires local 0.1 µF ceramic bypass capacitor placed ≤2 mm from pin to suppress supply coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables direct interfacing with ADCs/DACs and battery-voltage-referenced sensors without external level shifters. |
| 5 MHz GBWP with 5 V/µs slew rate | Supports closed-loop bandwidths >100 kHz in gain-of-10 configurations - sufficient for GSM/EDGE envelope detection. |
| Shutdown mode (0.2 µA IQ) | Reduces system-level standby power in TDMA time-slot architectures where amplifiers are inactive 50–90% of the time. |
| 600-Ω load drive capability | Eliminates need for external buffer stages in RF power detector outputs and analog front-end signal routing. |
| Industrial temperature range (−40°C to +85°C) | Validated performance across automotive cabin, industrial handheld, and outdoor wireless LAN environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail, low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461IDBVR | No shutdown pin; 6.4 MHz GBWP; 1.5 mA supply current; 2.5 mV max VOS | Lacks active power gating - unsuitable for TDMA burst-mode systems requiring microamp-level sleep current | Select when shutdown is unnecessary and higher bandwidth is prioritized over quiescent power |
| OPA316IDBVR | 2 MHz GBWP; 0.4 µA shutdown current; 0.5 mV max VOS; 10 V/µs slew rate | Lower bandwidth limits use in >5 MHz envelope detection; superior VOS benefits precision DC-coupled sensor paths | Select for ultra-low-offset, low-power sensor signal conditioning where speed is secondary to accuracy |
Compared with TLV2461IDBVR and OPA316IDBVR, LMV711M6X/NOPB uniquely balances 5 MHz bandwidth, sub-1 µA shutdown current, and 600-Ω drive strength - making it optimal for RF front-end bias control where both speed and power gating are mandatory.

FAQ
What is the maximum capacitive load the LMV711M6X/NOPB can drive without external compensation?
The LMV711M6X/NOPB can directly drive up to 200 pF in unity-gain follower configuration without oscillation or instability. This is verified per TI's characterization data and applies across 2.7–5 V supply and −40°C to +85°C. For loads exceeding 200 pF, a series isolation resistor (RISO) between the LMV711M6X/NOPB output and the capacitive load is required to maintain phase margin.
Does the LMV711M6X/NOPB support true rail-to-rail input common-mode voltage range?
Yes - the LMV711M6X/NOPB accepts input voltages from V− −0.3 V to V+ +0.3 V, confirmed in Electrical Characteristics tables for both 2.7 V and 5 V operation. This extended range enables high-side current sensing and direct interfacing with battery-referenced signals without external level shifting.
What happens to the output of the LMV711M6X/NOPB during shutdown?
When the SD pin is pulled low, the LMV711M6X/NOPB enters shutdown mode and its output settles to approximately 50–200 mV above V− (as specified in VO(SD) parameter). Unlike the LMV715-N, the LMV711M6X/NOPB does not tri-state its output - it remains in a defined low-voltage state, avoiding floating nodes in downstream circuitry.
Can the LMV711M6X/NOPB operate from a 2.7-V single supply?
Yes - the LMV711M6X/NOPB is fully characterized and guaranteed to operate from 2.7 V to 5 V single supply, with all key parameters (GBWP, slew rate, VOS, CMRR, PSRR) specified at 2.7 V in the datasheet. Its rail-to-rail I/O and low 1.7 mA supply current make it ideal for 2.7–3.3 V battery-powered systems.
Is the LMV711M6X/NOPB pin-compatible with other members of the LMV71x-N family?
The LMV711M6X/NOPB shares the same 6-pin SOT-23 (DBV) package and pinout as the LMV715-N, but differs electrically: the LMV715-N tri-states its output in shutdown, whereas the LMV711M6X/NOPB drives to ~50 mV above V−. The LMV710-N is 5-pin and not pin-compatible.
