Product details
Overview
LMV715IDBVRE4 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-designed for precision signal conditioning in battery-powered RF power amplifier control circuits.
For engineers reviewing the LMV715IDBVRE4 datasheet, LMV715IDBVRE4 pinout, LMV715IDBVRE4 application, or LMV715IDBVRE4 equivalent, key selection criteria include shutdown leakage current (1 pA), output drive into 600 Ω (±25 mA), rail-to-rail swing at 2.7 V/5 V supply, and guaranteed operation from –40°C to 85°C.
Technical Context
The LMV715IDBVRE4 employs BiCMOS process technology to achieve high output current drive while maintaining low quiescent current (1.7 mA typical ON mode, 0.2 µA typical shutdown). Its input stage extends 200 mV beyond rails, enabling accurate sensing near supply boundaries in AGC and detector circuits.
Unlike the LMV710 (5-pin, no shutdown) and LMV711 (6-pin, shutdown with 50–200 mV output during disable), the LMV715IDBVRE4 features ultra-low shutdown leakage (1 pA) and 32 pF output capacitance in shutdown mode-critical for minimizing parasitic loading in RF front-end bias control paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - supports single-supply operation in portable 3.3 V and 5 V systems without level-shifting. |
| Gain Bandwidth Product | 5 MHz - enables stable closed-loop gain up to ~100× at 50 kHz for RF detector filtering and temperature compensation loops. |
| Slew Rate | 5 V/µs - sufficient for settling <1 µs on 1 V step inputs, critical for fast AGC response in GSM/CDMA power amp control. |
| Input Offset Voltage | 0.4 mV typ, 3 mV max - ensures sub-mV error in precision DC-coupled sensor interfaces and feedback paths. |
| Shutdown Current | 0.2 µA typ - reduces system standby power by >99.9% vs active mode, extending battery life in Bluetooth/WLAN sleep cycles. |
| Output Short-Circuit Current | ±25 mA min - drives heavy capacitive loads or low-impedance bias networks without external buffers in PA control lines. |
| Input Bias Current | 4 pA typ - minimizes voltage error across high-impedance source networks (e.g., thermistor dividers, RF detector outputs). |
Pinout & Package
SOT-23-6 (DBV) package: 2.9 mm × 1.6 mm × 1.15 mm body, surface-mount, RoHS-compliant, moisture sensitivity level 1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail swing into 600 Ω load; capable of sourcing/sinking ±25 mA for direct PA bias control. |
| 2 (VCC−) | Negative supply rail | Ground reference for single-supply operation; supports true rail-to-rail input common-mode range down to VCC− − 0.2 V. |
| 3 (IN+) | Non-inverting input | Accepts signals 200 mV beyond rails; enables accurate sensing of battery voltage or detector output near ground. |
| 4 (VCC+) | Positive supply rail | 2.7–5 V input; supplies internal bias and output stage; low dropout design maintains regulation under load transients. |
| 5 (SHUTDOWN) | Active-low enable control | Pulled low (<0.8 V) disables amplifier; draws only 1 pA leakage and presents 32 pF capacitance to minimize RF coupling. |
| 6 (IN−) | Inverting input | Differential input node for closed-loop configurations; high CMRR (70 dB min) rejects supply noise in noisy RF environments. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 2.7 V systems-input accepts 0–2.9 V, output swings within 20 mV of rails into 600 Ω. |
| Ultra-low shutdown leakage | 1 pA typical IO(SD) prevents unintended bias drift in RF power amplifier shutdown states, preserving calibration integrity. |
| High output current drive | ±25 mA minimum sourcing/sinking capability eliminates need for external buffer stages in GSM/TDMA PA control loops. |
| Low input voltage noise | 20 nV/√Hz at 1 kHz supports clean amplification of weak RF detector signals without degrading SNR in Bluetooth receivers. |
| Fast turn-on time | <10 µs activation from shutdown allows rapid re-engagement during TDMA burst intervals without timing penalty. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV711IDBVRE4 | Same SOT-23-6 package and pinout; shutdown output voltage 50–200 mV (not high-Z); higher shutdown current (0.2 µA vs 1 pA). | Less suitable for RF bias control where shutdown-state leakage must be minimized; acceptable for general-purpose shutdown use. | Select LMV711IDBVRE4 only if output clamping during shutdown is acceptable and ultra-low leakage is not required. |
| MCP6001T-E/OT | 5-pin SOT-23; no shutdown pin; 1 µA supply current; 1 MHz GBW; rail-to-rail I/O; 2 mV offset. | Lacks shutdown functionality; lower bandwidth limits use in fast AGC or detector buffering; smaller footprint but incompatible pinout. | Choose MCP6001T-E/OT only for cost-sensitive, non-shutdown applications requiring minimal board area and relaxed speed requirements. |
Compared with LMV711IDBVRE4, LMV715IDBVRE4 provides superior shutdown isolation for RF bias networks; compared with MCP6001T-E/OT, it delivers 5× higher bandwidth and integrated shutdown-making LMV715IDBVRE4 the only option meeting GSM/CDMA PA control timing and leakage constraints.

FAQ
What is the shutdown pin behavior of the LMV715IDBVRE4?
The SHUTDOWN pin (Pin 5) is active-low: pulling it below 0.8 V disables the amplifier, reducing supply current to 0.2 µA typical and placing the output in high-impedance state with only 1 pA leakage. This behavior is confirmed in the Electrical Characteristics table for LMV715-specific parameters including IO(SD) and CO(SD). The LMV715IDBVRE4 differs from LMV711 by offering true high-Z shutdown rather than clamped output.
Does the LMV715IDBVRE4 support rail-to-rail input at 2.7 V supply?
Yes, the LMV715IDBVRE4 supports rail-to-rail input with a common-mode range extending 200 mV beyond both rails-verified at 2.7 V supply where VICR is specified from –0.2 V to 2.9 V. This enables accurate sensing of signals near ground or VCC in low-voltage portable systems, as documented in the Electrical Characteristics tables for both 2.7 V and 5 V operating conditions.
What is the maximum output current drive capability of the LMV715IDBVRE4?
The LMV715IDBVRE4 delivers ±25 mA minimum output current into short-circuit conditions, with sourcing and sinking performance characterized across temperature (–40°C to 85°C) and supply voltages (2.7 V and 5 V). This high drive strength is explicitly listed under IOS in the Electrical Characteristics tables and enables direct interface to RF power amplifier bias networks without external buffers.
How does the LMV715IDBVRE4 compare to the LMV710IDBVRE4 in pin compatibility?
The LMV715IDBVRE4 is not pin-compatible with the LMV710IDBVRE4: LMV715 uses SOT-23-6 (6 pins), while LMV710 uses SOT-23-5 (5 pins) and lacks a shutdown pin. Pin mapping differs entirely-LMV710 has no Pin 5 (SHUTDOWN) or Pin 6 (IN− is relocated), making PCB redesign mandatory. This distinction is clearly shown in the top-view package diagrams provided in the datasheet.
Is the LMV715IDBVRE4 suitable for automotive applications?
No, the LMV715IDBVRE4 is characterized for –40°C to +85°C operation and is not qualified to AEC-Q200 or ISO/TS 16949 standards. Texas Instruments explicitly states that LMV71x devices are intended for portable electronics-not automotive environments-unless specifically designated as automotive-grade. For automotive use, designers must select TI's automotive-qualified op-amp families such as TLVx376 or OPAx192.
