Product details
Overview
LMV711IDCKR from Texas Instruments is a single, low-power, rail-to-rail input/output (RRIO) operational amplifier in SC-70-6 package, featuring 5 MHz gain bandwidth, 5 V/µs slew rate, 0.4 mV typical input offset voltage, and active shutdown with <10 µs turn-on time-designed for precision signal conditioning in battery-powered RF power control circuits.
For engineers reviewing the LMV711IDCKR datasheet, LMV711IDCKR pinout, LMV711IDCKR application, or LMV711IDCKR equivalent, this page delivers verified electrical specifications, SC-70-6 terminal mapping, real-world use cases in GSM/CDMA power amp control and AGC loops, and two validated alternative op-amps with documented functional and interface differences.
Technical Context
The LMV711IDCKR employs BiCMOS input stage architecture enabling rail-to-rail input common-mode range (–0.2 V to 5.2 V at 5 V supply) and rail-to-rail output swing into 600 Ω load. Its internal Class AB output stage delivers ±25 mA sourcing/sinking capability while maintaining stability under capacitive loads.
Shutdown functionality is implemented via dedicated SHDN pin (pin 5), asserting logic-low disables amplifier output and reduces ICC to 0.2 µA typical-enabling rapid power cycling in time-critical wireless subsystems without external sequencing circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 5 V - supports dual-cell Li-ion and single-cell alkaline/battery systems without LDO pre-regulation. |
| Gain Bandwidth Product | 5 MHz - enables stable closed-loop operation up to 100 kHz with ≥60° phase margin into 10 kΩ//100 pF loads. |
| Slew Rate | 5 V/µs - ensures ≤200 ns settling to 0.1% for 2 V step inputs, critical for fast AGC response in CDMA transceivers. |
| Input Offset Voltage | 0.4 mV typ, 3 mV max - minimizes DC error in precision current-sense feedback paths for PA bias control. |
| Shutdown Current | 0.2 µA typ - reduces system standby power by >99.9% versus active mode (1.7 mA), extending battery life in idle intervals. |
| Output Drive | ±25 mA into 600 Ω - directly drives RF power detector diodes or DAC reference buffers without external gain stages. |
| Input Voltage Noise | 20 nV/√Hz at 1 kHz - preserves SNR in low-level RF envelope detection and temperature compensation circuits. |
Pinout & Package
LMV711IDCKR uses SC-70-6 (DCK) package: 2.0 mm × 1.25 mm footprint, 0.65 mm pitch, 0.9 mm max height - optimized for space-constrained mobile RF front-end modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output node - rail-to-rail swing into 600 Ω, capable of sourcing/sinking 25 mA for direct interface to RF detector diodes. |
| 2 | VCC− | Negative supply rail - accepts ground or negative bias; input common-mode extends 200 mV beyond this rail. |
| 3 | IN+ | Non-inverting input - high-impedance BiCMOS node (4 pA bias current) for precision sensor or reference signal routing. |
| 4 | VCC+ | Positive supply rail - operates from 2.7 V to 5 V; PSRR >70 dB ensures immunity to digital supply noise. |
| 5 | SHUTDOWN | Dedicated enable control - logic-high (>2 V) enables amplifier; logic-low (<0.8 V) forces output high-impedance and cuts ICC to 0.2 µA. |
| 6 | IN− | Inverting input - matched to IN+ for <3 mV offset; used in closed-loop configurations for PA bias current regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization across 2.7–5 V supplies - eliminates level-shifting components in single-supply RF detector interfaces. |
| Active shutdown with fast wake-up | <10 µs turn-on time allows synchronous power gating with TDMA burst timing, reducing average current in GSM/GPRS transmit slots. |
| High output current drive | ±25 mA capability supports direct driving of RF power detector diodes and low-impedance DAC reference buffers without external transistors. |
| Low input offset voltage | 0.4 mV typical offset ensures <0.5% error in closed-loop PA bias current control at 100 mA setpoint - critical for EVM compliance. |
| Wide input common-mode range | Operates with inputs 200 mV beyond rails - accommodates ground-referenced sensors and rail-splitter references in compact RF modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail, low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV721IDCKR | Higher 10 MHz GBW, 8 V/µs slew rate, no shutdown pin - requires external enable circuitry. | Better suited for wideband IF amplification but lacks integrated power gating for burst-mode systems. | Select when bandwidth >5 MHz is required and shutdown timing is managed externally. |
| MCP6001UT-I/OT | 1 kHz GBW, 0.6 V/µs slew rate, 100 nA input bias, no shutdown - lower performance, higher power efficiency at ultra-low frequencies. | Appropriate for slow-settling sensor interfaces (e.g., battery voltage monitoring) where fast response is unnecessary. | Choose for cost-sensitive, low-frequency (<100 kHz) applications where shutdown is not required. |
Compared with LMV711IDCKR, LMV721IDCKR trades integrated shutdown for higher speed, while MCP6001UT-I/OT sacrifices bandwidth and precision for ultra-low quiescent current - making LMV711IDCKR the optimal balance of speed, power control, and accuracy for RF power management.

FAQ
What is the operating temperature range for LMV711IDCKR?
The LMV711IDCKR is characterized for operation from –40°C to +85°C ambient temperature. This industrial-grade range ensures reliable performance in mobile handset environments, automotive infotainment RF modules, and outdoor wireless access points where thermal cycling occurs. All key parameters-including input offset voltage, gain bandwidth, and shutdown current-are guaranteed across this full range per the SLOS463A datasheet.
Does LMV711IDCKR support true rail-to-rail input and output operation?
Yes, LMV711IDCKR supports rail-to-rail input common-mode range extending 200 mV beyond both supply rails (e.g., –0.2 V to 5.2 V at 5 V supply) and rail-to-rail output swing into 600 Ω loads. This is achieved via BiCMOS input stage and Class AB output stage, enabling direct interfacing with ground-referenced sensors and single-supply ADCs without level-shifting components-verified in Figures 3–6 of the LMV711IDCKR datasheet.
What is the typical shutdown current of LMV711IDCKR and how is it controlled?
The LMV711IDCKR draws 0.2 µA typical supply current in shutdown mode, activated by pulling the SHDN pin (pin 5) to logic-low (<0.8 V). This feature reduces total system standby power by >99.9% versus active mode (1.7 mA), making LMV711IDCKR ideal for TDMA/GSM burst-mode applications. Turn-on time from shutdown is <10 µs, allowing synchronization with RF transmit timing windows without latency penalties.
Can LMV711IDCKR drive a 600 Ω load while maintaining rail-to-rail output swing?
Yes, LMV711IDCKR guarantees rail-to-rail output swing into 600 Ω loads across its full operating temperature and supply range (2.7 V to 5 V). At 5 V supply, VOH reaches 4.8 V and VOL drops to 0.3 V into 600 Ω (per Electrical Characteristics Table, page 5), delivering ±25 mA sourcing/sinking capability-sufficient to directly drive RF detector diodes and low-impedance reference buffers without external buffering.
What package type and footprint does LMV711IDCKR use, and is it RoHS compliant?
LMV711IDCKR uses the SC-70-6 (DCK) package: 2.0 mm × 1.25 mm body size, 0.65 mm lead pitch, and 0.9 mm maximum height. It is RoHS-compliant and green (Pb-free, no Sb/Br), with CU NIPDAU lead finish and JEDEC MSL Level-1 rating (260°C peak reflow). This ultra-small footprint supports high-density RF front-end layouts in smartphones, wearables, and IoT edge nodes where board space is constrained.
