Product details
Overview
LMV712IDGSR from Texas Instruments is a dual rail-to-rail input/output (RRIO) operational amplifier with independent shutdown control, 5-MHz gain bandwidth, 5-V/μs slew rate, and 20-nV/√Hz input voltage noise. It operates from 2.7 V to 5 V and delivers 1.22 mA/channel supply current in active mode, targeting low-power portable signal conditioning in cellular phones and wireless LAN front-ends.
For engineers reviewing the LMV712IDGSR datasheet, LMV712IDGSR pinout, LMV712IDGSR application, or LMV712IDGSR equivalent, this page provides verified package mapping (MSOP-10 DGS), confirmed shutdown timing (2.2–4.6 μs turn-on), rail-to-rail output swing at 600 Ω load, and real-world design implications for battery-powered analog signal chains.
Technical Context
The LMV712IDGSR integrates two independent BiCMOS op-amps with separate shutdown pins (1SD, 2SD), enabling per-channel power gating without affecting the other amplifier. Each channel features unity-gain stability and supports capacitive loads up to 200 pF without oscillation.
Its input stage uses a complementary differential pair for rail-to-rail common-mode range (–0.3 V to VCC+ + 0.4 V), while the output stage delivers true rail-to-rail swing-within 12 mV of VCC+ and 15 mV of VCC– at 10-kΩ load-and sustains ±35 mA sourcing/sinking capability at 5 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 5 MHz - Enables stable closed-loop operation up to ~400 kHz at gain = 12, suitable for anti-aliasing and sensor amplification. |
| Slew Rate | 5 V/μs - Supports 1-Vpp signals up to ~800 kHz without distortion; critical for fast-settling ADC drivers. |
| Input Voltage Noise | 20 nV/√Hz at 1 kHz - Low-noise performance preserves SNR in microphone preamps and precision sensor interfaces. |
| Supply Current per Channel | 1.22 mA (typ) at 2.7 V - Enables dual-channel amplification in 3-V battery systems with <2.5 mA total quiescent draw. |
| Shutdown Current | 1.5 μA (typ) per channel - Reduces system standby power by >99% versus active mode; ideal for duty-cycled sensing. |
| Input Offset Voltage | ≤3 mV (max) - Minimizes DC error in single-supply transimpedance or level-shifting circuits without trimming. |
| Common-Mode Range | Rail-to-rail (–0.3 V to VCC+ + 0.4 V) - Accepts inputs down to ground and up to supply rail, simplifying interfacing with ADCs and DACs. |
Pinout & Package
LMV712IDGSR is housed in a 10-pin MSOP (DGS) package measuring 3 mm × 3 mm × 1.05 mm, optimized for space-constrained portable PCBs. Thermal resistance θJA is 165°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1SD | Independent shutdown control for Amplifier 1; logic-high (>VSD_ON) enables, logic-low ( |
| 2 | 1IN− | Inverting input of Amplifier 1; supports rail-to-rail common-mode voltage and exhibits 115 pA (typ) input bias current. |
| 3 | 1IN+ | Non-inverting input of Amplifier 1; matched to Pin 2 for low offset; CMVR extends to VCC– – 0.4 V. |
| 4 | 1OUT | Amplifier 1 output; delivers rail-to-rail swing (e.g., 0.01 V to 2.68 V at 10 kΩ, 2.7 V supply) with 75 mA short-circuit rating. |
| 5 | VCC− | Negative supply rail (typically GND in single-supply use); must be decoupled near pin with 0.1-μF ceramic capacitor. |
| 6 | VCC+ | Positive supply rail (2.7 V to 5 V); supplies both amplifiers and shutdown logic; max rating 5.5 V absolute. |
| 7 | 2IN+ | Non-inverting input of Amplifier 2; electrically identical to Pin 3; enables dual-channel synchronous signal processing. |
| 8 | 2IN− | Inverting input of Amplifier 2; matched to Pin 7; shares same CMRR (≥50 dB) and PSRR (≥70 dB) as Channel 1. |
| 9 | 2OUT | Amplifier 2 output; independently controllable; maintains 2.2–4.6 μs turn-on time from shutdown without output glitch. |
| 10 | 2SD | Independent shutdown control for Amplifier 2; functionally identical to Pin 1; allows asymmetric power management. |
Key Features
| Feature | Design Value |
|---|---|
| Independent per-channel shutdown | Enables dynamic power scaling in multi-sensor systems-e.g., disable unused channel during sleep without firmware reconfiguration. |
| Rail-to-rail I/O at 2.7 V | Preserves full dynamic range in 3-V systems: output swings within 12 mV of rails, input accepts 0 V to 2.7 V common-mode. |
| Stable driving 200-pF load | Eliminates need for external isolation resistors when buffering SAR ADC inputs or driving long PCB traces. |
| Low 1.5-μA shutdown ICC | Reduces system standby current to sub-microamp levels-critical for coin-cell–powered IoT endpoints with multi-year battery life. |
| 20-nV/√Hz input noise | Supports high-resolution measurement of µV-level signals from thermocouples or bridge sensors without added gain-stage noise. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual RRIO op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6022-I/SN (Microchip) | Lower GBW (10 MHz), higher supply current (1 mA/channel), no shutdown pins, SOIC-8 package. | Lacks per-channel power control; unsuitable for duty-cycled systems requiring microamp standby. | Select when higher speed is needed and shutdown is managed externally via supply switching. |
| TLV2462IDR (TI) | Higher noise (28 nV/√Hz), slower slew rate (0.6 V/μs), no shutdown, same MSOP-10 package. | Cannot support fast-settling ADC drivers or low-noise sensor front-ends requiring <25 nV/√Hz. | Choose only if cost is primary constraint and 5-MHz GBW/5-V/μs slew rate are not required. |
Compared with MCP6022-I/SN and TLV2462IDR, LMV712IDGSR uniquely combines independent shutdown, 5-MHz bandwidth, and 20-nV/√Hz noise in an MSOP-10 package-enabling lower system power and higher fidelity in portable RF and medical signal chains where per-channel control and low-noise precision are co-required.

FAQ
What is the maximum capacitive load the LMV712IDGSR can drive without oscillation?
The LMV712IDGSR is specified to remain stable driving capacitive loads up to 200 pF without external compensation. This capability eliminates series isolation resistors in ADC driver and filter applications, preserving signal integrity and reducing board area. The stability margin is validated across temperature and supply voltage (2.7 V to 5 V) per TI SLOS485 datasheet Section 7.5.
Does the LMV712IDGSR support true rail-to-rail output swing at 600 Ω load?
Yes. At 2.7 V supply, LMV712IDGSR delivers VOH ≥ 2.52 V and VOL ≤ 0.23 V into 600 Ω (per datasheet Table 1), achieving <100 mV from each rail. At 5 V supply, it achieves VOH ≥ 4.82 V and VOL ≤ 0.3 V. This rail-to-rail output ensures maximum dynamic range utilization in single-supply data acquisition systems.
What is the typical turn-on time from shutdown for the LMV712IDGSR?
The LMV712IDGSR exhibits a typical turn-on time of 2.2 μs at 2.7 V supply and 1.6 μs at 5 V supply (datasheet Sections 6.5 and 6.6). Output ramps smoothly without glitches, making it suitable for burst-mode signal chains such as TDMA-based RF receivers where rapid channel activation is required.
Can both amplifiers in the LMV712IDGSR be disabled simultaneously?
Yes. Driving both 1SD (Pin 1) and 2SD (Pin 10) low disables both amplifiers independently, reducing total supply current to ≤2 μA (typ). This dual-shutdown capability enables complete analog subsystem power-down in portable devices during deep sleep, significantly extending battery runtime between charges.
Is the LMV712IDGSR RoHS-compliant and lead-free?
Yes. LMV712IDGSR carries TI's "Green (RoHS & no Sb/Br)" eco-plan designation, confirming compliance with RoHS Directive 2011/65/EU and absence of bromine/antimony flame retardants. Its CU NIPDAU terminal finish meets JEDEC Level-1 moisture sensitivity requirements for standard reflow assembly.
