Product details
Overview
LMV710IDCKRE4 from Texas Instruments is a single, low-power, rail-to-rail input/output (RRIO) operational amplifier in SC-70-5 package, featuring 5 MHz gain bandwidth, 5 V/µs slew rate, 0.4 mV typical input offset voltage, and rail-to-rail swing into 600 Ω - optimized for GSM/CDMA power amplifier control and RF detector circuits in portable wireless devices.
For engineers reviewing the LMV710IDCKRE4 datasheet, LMV710IDCKRE4 pinout, LMV710IDCKRE4 application, or LMV710IDCKRE4 equivalent, key selection criteria include its 2.7–5 V supply range, 1.7 mA typical supply current in active mode, 0.2 µA shutdown current (not applicable to LMV710), input common-mode range extending 200 mV beyond rails, and high output drive capability up to ±35 mA.
Technical Context
The LMV710IDCKRE4 employs BiCMOS process technology to achieve both low input bias current (4 pA typ) and high output current drive (±35 mA min at 5 V). Its RRIO architecture supports signal conditioning across full supply range, with input common-mode voltage spanning –0.2 V to 5.2 V (at VCC = 5 V) and output swing within 0.05 V of rails into 600 Ω.
Unlike LMV711/LMV715, the LMV710 lacks a dedicated shutdown pin - it is a 5-pin device without enable functionality. Its simplified topology eliminates internal bias control circuitry for shutdown, resulting in lower quiescent current variation and absence of turn-on delay specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - compatible with single-cell Li-ion and 3.3 V system rails. |
| Gain Bandwidth Product | 5 MHz typ - supports stable closed-loop operation up to ~400 kHz with unity-gain stability. |
| Slew Rate | 5 V/µs typ - enables clean amplification of fast-settling signals in AGC and detector feedback paths. |
| Input Offset Voltage | 0.4 mV typ, 3 mV max - ensures minimal DC error in precision sensor interfaces and temperature compensation loops. |
| Rail-to-Rail I/O | Input extends 200 mV beyond rails; output swings to within 0.05 V of rails into 600 Ω - maximizes dynamic range in low-voltage systems. |
| Supply Current (Active) | 1.7 mA typ at 2.7 V, 1.17 mA typ at 5 V - balances performance and battery life in always-on RF monitoring stages. |
| Input Bias Current | 4 pA typ - preserves high-impedance source integrity in RF power detector and thermistor signal chains. |
Pinout & Package
LMV710IDCKRE4 is housed in a 5-pin SC-70 (DCK) package, measuring 2.0 mm × 1.25 mm × 0.9 mm, with moisture sensitivity level (MSL) 1 and lead-free (RoHS & no Sb/Br) finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output terminal - drives loads up to ±35 mA while maintaining rail-to-rail swing into 600 Ω. |
| 2 | V− | Negative supply rail (GND when single-supply) - referenced for input common-mode and output swing. |
| 3 | IN+ | Non-inverting input - accepts signals from –0.2 V to 5.2 V (at 5 V supply), enabling true rail-to-rail sensing. |
| 4 | V+ | Positive supply rail - supports operation from 2.7 V to 5 V with <1.7 mA quiescent draw. |
| 5 | IN− | Inverting input - used for closed-loop configurations including transimpedance and differential amplification. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 2.7–5 V supply range without external level-shifting in battery-powered RF front-ends. |
| High output current drive | ±35 mA sourcing/sinking capability allows direct interface to power amplifier bias control lines without external buffers. |
| Low input offset voltage | 0.4 mV typical offset minimizes DC error in closed-loop RF power control and temperature-compensated bias networks. |
| Ultra-low input bias current | 4 pA typical bias current prevents loading of high-impedance RF detector diodes and thermistor dividers. |
| 5 MHz bandwidth at low power | Delivers sufficient small-signal response for GSM/CDMA envelope detection and AGC loop dynamics without excessive supply current. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV721IDBVR | Higher GBW (10 MHz), same SC-70-5 package, but higher supply current (1.25 mA vs 1.17 mA at 5 V) and no rail-to-rail input. | Limited to applications where input common-mode range ≥1 V from rails is acceptable; unsuitable for true rail-sensing. | Select when higher bandwidth is required and input voltage stays >1 V above V−. |
| TLV2461CDBVR | RRIO, 6.4 MHz GBW, 1.5 mA supply current, but 2 mV max VIO and 50 pA IIB - less precise for low-level RF detection. | Acceptable for general-purpose portable analog, but insufficient offset/bias performance for precision detector or PA control loops. | Choose for cost-sensitive designs where 0.4 mV VIO and 4 pA IIB are not mandatory. |
Compared with LMV710IDCKRE4, LMV721IDBVR trades rail-to-rail input for doubled bandwidth, while TLV2461CDBVR offers broader supply range (2.7–6 V) but sacrifices input precision - making LMV710IDCKRE4 optimal for RF control where low VIO, ultra-low IIB, and true RRIO are simultaneously required.

FAQ
Does LMV710IDCKRE4 have a shutdown pin?
No, LMV710IDCKRE4 does not include a shutdown function. It is a 5-pin RRIO op-amp without enable control - unlike the 6-pin LMV711/LMV715 variants which feature a dedicated SHDN pin. The LMV710IDCKRE4 operates continuously when powered; system-level power gating must be implemented externally if needed.
What is the maximum output current capability of LMV710IDCKRE4?
LMV710IDCKRE4 delivers ±35 mA minimum sinking/sourcing current into loads while maintaining rail-to-rail output swing. At VCC = 5 V and RL = 600 Ω, it sustains VOH ≥ 4.8 V and VOL ≤ 0.3 V, confirming robust drive strength for direct interface to PA bias control lines and detector loads.
Is LMV710IDCKRE4 suitable for single-supply operation at 3.3 V?
Yes, LMV710IDCKRE4 is fully specified for 2.7 V to 5 V operation, including 3.3 V single-supply use. Its rail-to-rail input accepts signals from –0.2 V to 3.5 V, and output swings within 0.05 V of rails into 600 Ω - making it ideal for 3.3 V signal chains in Bluetooth and WLAN modules.
What is the input voltage noise density of LMV710IDCKRE4?
LMV710IDCKRE4 exhibits 20 nV/√Hz input-referred voltage noise at 1 kHz, measured at VCC = 3.2 V. This low noise floor supports high-fidelity amplification of weak RF detector outputs and thermistor bridge signals without degrading system SNR in portable wireless applications.
How does LMV710IDCKRE4 differ from LMV711IDCKRE4?
LMV710IDCKRE4 is a 5-pin RRIO op-amp without shutdown; LMV711IDCKRE4 is a 6-pin variant with identical core specs plus SHDN pin, 0.2 µA shutdown current, and <10 µs turn-on time. Pin compatibility is not maintained - LMV711 requires re-layout due to added shutdown terminal and different pinout.
