Product details
Overview
LMV711IDBVRE4 from Texas Instruments is a single, low-power, rail-to-rail input/output (RRIO) operational amplifier in SOT-23-6 package with shutdown control, 5 MHz gain bandwidth, 5 V/µs slew rate, and 0.4 mV typical input offset voltage. It delivers 28 mA sourcing/40 mA sinking output drive into 600 Ω and operates from 2.7 V to 5 V supply, targeting RF power amplifier control in GSM/CDMA handsets.
For engineers reviewing the LMV711IDBVRE4 datasheet, LMV711IDBVRE4 pinout, LMV711IDBVRE4 application, or LMV711IDBVRE4 equivalent, key selection criteria include shutdown current (0.2 µA typ), turn-on time (<10 µs), rail-to-rail swing at 600 Ω load, input common-mode range extending 200 mV beyond rails, and guaranteed performance over –40°C to 85°C.
Technical Context
The LMV711IDBVRE4 uses BiCMOS process technology to achieve high output current drive while maintaining low quiescent current in both active and shutdown modes. Its internal architecture includes rail-to-rail input stage with p-n differential pairs and Class AB output stage enabling full-swing operation into heavy loads.
Shutdown functionality is implemented via dedicated SHUTDOWN pin (Pin 5), which disables the amplifier core and reduces supply current to 0.2 µA typical. The device features <10 µs turn-on time and maintains output leakage <200 mV during shutdown-critical for precision bias control in RF front-end applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - supports single-supply battery-powered systems including Li-ion (3.0–4.2 V) and dual-cell alkaline (2.7–3.6 V). |
| Gain Bandwidth Product | 5 MHz typ - enables stable closed-loop operation up to ~400 kHz with unity-gain stability into capacitive loads. |
| Slew Rate | 5 V/µs typ - sufficient for settling 2 V step in <500 ns, suitable for AGC loop response in RF detectors. |
| Input Offset Voltage | 0.4 mV typ / 3 mV max - ensures minimal DC error in precision sensor signal conditioning and temperature compensation circuits. |
| Output Drive Capability | 28 mA sourcing / 40 mA sinking into 600 Ω - directly drives RF power amplifier bias networks without external buffers. |
| Shutdown Current | 0.2 µA typ - reduces system standby power by >99% versus active mode (1.7 mA), critical for mobile phone sleep cycles. |
| Input Common-Mode Range | Extends 200 mV beyond rails - allows direct sensing of signals near ground or VCC in single-supply configurations. |
Pinout & Package
SOT-23-6 (DBV) package: 2.9 mm × 1.6 mm × 1.15 mm body, gull-wing leads, RoHS-compliant Cu-NiPdAu finish, MSL Level-1 (260°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output node - rail-to-rail capable, drives 600 Ω load to within 0.23 V of rails at 5 V supply. |
| 2 | VCC− | Negative supply terminal - connects to GND in single-supply operation; supports split-rail use down to ±2.5 V. |
| 3 | IN+ | Non-inverting input - accepts common-mode voltages from –0.3 V to 5.3 V at 5 V supply, enabling direct sensor interfacing. |
| 4 | VCC+ | Positive supply terminal - accepts 2.7–5 V; supplies internal bias and output stage; decoupling recommended ≤100 nF. |
| 5 | SHUTDOWN | Digital enable input - logic high (>2 V at 5 V supply) enables amplifier; logic low (<0.8 V) places device in ultra-low-ICC state. |
| 6 | IN− | Inverting input - differential pair input with 4 pA typical bias current; matched to IN+ for low offset drift. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 2.7–5 V single-supply systems without level-shifting circuitry. |
| High output current drive | Delivers 28 mA sourcing and 40 mA sinking into 600 Ω - eliminates need for external buffer stages in RF PA bias control. |
| Ultra-fast shutdown recovery | Turn-on time <10 µs - meets tight timing constraints in TDMA burst-mode transceivers requiring rapid amplifier activation. |
| Low input offset voltage | 0.4 mV typical - minimizes DC error accumulation in closed-loop AGC and temperature compensation feedback paths. |
| Wide input common-mode range | Operates with inputs 200 mV beyond either rail - supports direct connection to resistive divider networks referenced to VCC or GND. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV712MMX/NOPB | Dual-channel, 10 MHz GBW, no shutdown pin, 1.2 mA supply current per channel. | Lacks shutdown function; higher bandwidth but higher power - suited for non-battery-critical dual-signal paths. | Select when dual amplifiers are needed and shutdown is unnecessary; not drop-in due to pin count and feature mismatch. |
| MCP6001T-E/OT | Single-channel, 1 MHz GBW, 0.6 V/µs slew rate, 1.6 µA supply current, no shutdown. | Lower speed and drive - adequate for low-frequency sensor buffering but insufficient for RF PA control or fast AGC. | Choose for cost-sensitive, low-bandwidth applications where shutdown and high output current are not required. |
Compared with LMV711IDBVRE4, LMV712MMX/NOPB offers higher bandwidth but lacks shutdown and requires PCB redesign for dual-channel use, while MCP6001T-E/OT trades off speed and drive for ultra-low power without shutdown capability-making LMV711IDBVRE4 uniquely balanced for RF power control in portable wireless systems.

FAQ
What is the maximum supply voltage rating for LMV711IDBVRE4?
The absolute maximum supply voltage (VCC+ to VCC−) for LMV711IDBVRE4 is 6 V, but the recommended operating range is 2.7 V to 5 V. Operation above 5 V may compromise parametric guarantees such as input offset voltage, CMRR, and output swing. TI specifies all electrical characteristics at 2.7 V and 5 V supplies, and exceeding 5 V voids guaranteed performance per the SLOS463A datasheet.
Does LMV711IDBVRE4 support true rail-to-rail input with signals below ground?
Yes - LMV711IDBVRE4 supports input common-mode voltages down to VCC− − 0.3 V (e.g., –0.3 V when VCC− = GND). This extends 200 mV beyond the negative rail, enabling direct interface with signals referenced slightly below ground in single-supply systems, such as certain current-sense amplifier outputs or thermistor networks with negative offsets.
What is the output voltage swing of LMV711IDBVRE4 into a 600 Ω load at 5 V supply?
At 5 V supply and 25°C, LMV711IDBVRE4 delivers VOH = 4.8 V min and VOL = 0.3 V max into a 600 Ω load, representing rail-to-rail swing within 200 mV of each rail. This is confirmed in the Electrical Characteristics table (page 5, VCC+ = 5 V section) and enables full utilization of ADC input ranges or direct driving of RF transistor gates without level-shifting.
How does the shutdown pin (Pin 5) of LMV711IDBVRE4 behave electrically?
The SHUTDOWN pin of LMV711IDBVRE4 is a CMOS-compatible digital input: applying ≥2.0 V (at 5 V supply) enables normal operation, while ≤0.8 V disables the amplifier core and reduces ICC to 0.2 µA typical. The pin draws <100 nA in either state and has no internal pull-up/down - external logic or microcontroller GPIO must drive it actively.
Is LMV711IDBVRE4 suitable for driving capacitive loads, and what is its phase margin?
LMV711IDBVRE4 exhibits 60° phase margin at unity gain with resistive loads, but capacitive loading degrades stability. TI recommends limiting capacitive load to ≤100 pF without isolation resistance; for larger loads (e.g., ADC inputs), a 10–50 Ω series resistor at the output restores stability. This behavior is documented in Figure 23–28 (open-loop frequency response) and application guidance in the datasheet.
