Product details
Overview
LMV712IDGST 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-designed for low-power portable signal conditioning in battery-operated wireless transceivers.
For engineers reviewing the LMV712IDGST datasheet, LMV712IDGST pinout, LMV712IDGST application, or LMV712IDGST equivalent, key selection criteria include shutdown current (≤1.5 μA), rail-to-rail output swing at 600-Ω load, turn-on time (≤4.6 μs), and MSOP-10 package compatibility with space-constrained RF front-end designs.
Technical Context
The LMV712IDGST integrates two independent BiCMOS op-amps with separate shutdown pins (1SD, 2SD), enabling per-channel power gating without affecting the other amplifier. Each channel achieves unity-gain stability driving up to 200 pF capacitive loads.
Its input stage supports common-mode voltages from VCC– – 0.4 V to VCC+ + 0.4 V, and outputs swing within 10–230 mV of rails under 600-Ω load at 2.7 V or 5 V supply-enabling full dynamic range utilization in single-supply 3.3-V systems.
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 (e.g., active filter stages). |
| Slew Rate | 5 V/μs - supports clean 1-Vpp, 500-kHz sine wave output without distortion in audio or IF amplification. |
| Input Voltage Noise | 20 nV/√Hz at 1 kHz - critical for preserving SNR in low-level sensor signal amplification (e.g., microphone preamp). |
| Supply Current per Channel | 1.22 mA (ON), 1.5 μA (shutdown) - allows dynamic power scaling in duty-cycled RF receive paths. |
| Input Offset Voltage | ≤3 mV (max) - ensures ≤3-mV DC error in precision level-shifting or biasing circuits across –40°C to 85°C. |
| Rail-to-Rail I/O | Voltage range: VCC– – 0.4 V to VCC+ + 0.4 V inputs; output swing to within 10–230 mV of rails - maximizes ADC input range in 3.3-V data acquisition. |
| Turn-On Time | ≤4.6 μs (typical) - enables fast wake-up from shutdown in time-sliced receiver architectures (e.g., TDMA burst mode). |
Pinout & Package
LMV712IDGST is housed in a 10-pin MSOP (DGS) package, 3.0 mm × 3.0 mm × 1.0 mm, moisture sensitivity level 1, RoHS-compliant with Cu-NiPdAu finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1SD | Shutdown control for Amplifier 1: logic high (>4.5 V at 5 V supply) disables output; <0.8 V enables operation. |
| 2 | 1IN− | Inverting input of Amplifier 1 - accepts signals down to VCC– – 0.4 V, supporting true single-supply differential sensing. |
| 3 | 1IN+ | Non-inverting input of Amplifier 1 - matched bias current (<130 pA) minimizes offset drift in high-impedance sensor interfaces. |
| 4 | VCC− | Negative supply rail (GND in single-supply config) - shared return path for both amplifiers and shutdown logic. |
| 5 | 1OUT | Output of Amplifier 1 - delivers ±50 mA short-circuit current and drives 600-Ω loads to within 230 mV of rails at 2.7 V. |
| 6 | 2OUT | Output of Amplifier 2 - independently controllable; identical drive capability and rail-to-rail swing as Pin 5. |
| 7 | VCC+ | Positive supply rail (2.7–5 V) - powers both amplifiers and internal bias circuitry; PSRR ≥70 dB suppresses supply ripple. |
| 8 | 2IN+ | Non-inverting input of Amplifier 2 - electrically isolated from Amp 1; enables dual-path signal processing without crosstalk. |
| 9 | 2IN− | Inverting input of Amplifier 2 - supports differential configurations with matched CMVR and CMRR ≥50 dB. |
| 10 | 2SD | Shutdown control for Amplifier 2 - independent of Pin 1, allowing asymmetric power management (e.g., keep Amp 1 active while sleeping Amp 2). |
Key Features
| Feature | Design Value |
|---|---|
| Independent per-channel shutdown | Reduces total ICC to <2 μA (both channels off), enabling microamp-level sleep modes in portable IoT nodes. |
| Rail-to-rail input and output | Preserves full signal swing across 2.7–5 V supplies - eliminates external level-shifting in 3.3-V ADC driver or DAC buffer stages. |
| Low 20-nV/√Hz input voltage noise | Maintains >80-dB SNR for 100-mVpp, 10-kHz sensor signals - suitable for MEMS microphone preamplifiers and medical ECG front-ends. |
| Unity-gain stable with 200-pF load | Eliminates need for isolation resistors when driving ADC input capacitance or long PCB traces in compact layouts. |
| 2.2–4.6 μs turn-on time | Supports burst-mode operation in WLAN/WiFi receivers where amplifiers must activate synchronously with packet arrival. |
Applications
| Cellular Phone Front-End | Wireless LAN IF Amplifier |

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 |
|---|---|---|---|
| TLV2772IDGKR | Higher supply current (1.8 mA/ch), lower GBWP (4.8 MHz), no independent shutdown pins - uses single global shutdown. | Lacks per-channel power control; unsuitable for asymmetric power-gating architectures. | Select when system-level shutdown suffices and cost is prioritized over fine-grained power management. |
| OPA2316IDGKT | Lower noise (12 nV/√Hz), higher GBWP (10 MHz), but no shutdown function and higher ICC (1.6 mA/ch). | Cannot enter ultra-low-power state; requires external FET switching for power gating. | Select when noise and bandwidth dominate requirements and shutdown is implemented externally via discrete switches. |
Compared with TLV2772IDGKR and OPA2316IDGKT, the LMV712IDGST uniquely provides independent per-channel shutdown with sub-μA quiescent current, making it optimal for battery-powered systems requiring dynamic channel enable/disable without layout or firmware changes.

FAQ
What is the maximum capacitive load the LMV712IDGST can drive without oscillation?
The LMV712IDGST is unity-gain stable and specified to drive up to 200 pF capacitive loads without requiring external compensation or isolation resistors. This capability simplifies interface design to ADC inputs, long PCB traces, or LCD column drivers while maintaining phase margin ≥60° across temperature and supply voltage.
Does the LMV712IDGST support true single-supply operation with rail-to-rail inputs and outputs?
Yes, the LMV712IDGST supports true single-supply operation from 2.7 V to 5 V. Its inputs operate from VCC– – 0.4 V to VCC+ + 0.4 V, and outputs swing to within 10–230 mV of either rail depending on load and supply - enabling full utilization of 3.3-V ADC reference ranges without external level-shifting circuitry.
What is the typical turn-on time from shutdown for the LMV712IDGST?
The LMV712IDGST exhibits a typical turn-on time of 2.2 μs at 2.7 V supply and 4.6 μs at 5 V supply, measured from shutdown pin transition to output settling within 1% of final value. This fast wake-up supports time-sliced receiver architectures in TDMA-based wireless systems.
How does the independent shutdown feature of the LMV712IDGST improve power efficiency in dual-path systems?
The LMV712IDGST provides two dedicated shutdown pins (1SD and 2SD), allowing each amplifier to be disabled independently. In dual-path RF receivers, this enables one channel to remain active for monitoring while the other sleeps - reducing total ICC to <2 μA (both off) versus fixed 2.44-mA draw if both were always enabled.
What package type and dimensions does the LMV712IDGST use?
The LMV712IDGST uses the MSOP-10 (DGS) package: 3.0 mm × 3.0 mm footprint, 1.0 mm height, 0.5-mm lead pitch. It is RoHS-compliant with green (Pb-free, Sb/Br-free) construction and JEDEC MSL Level-1 rating - suitable for reflow assembly in high-density portable PCBs.
