Product details
Overview
LMV712LDX/NOPB from Texas Instruments is a dual rail-to-rail input/output operational amplifier with independent shutdown control per channel, designed for low-voltage portable systems. It delivers 5 MHz gain-bandwidth, 5 V/µs slew rate, 20 nV/√Hz input voltage noise, 1.22 mA/channel supply current, and operates from 2.7 V to 5.5 V - enabling precision signal conditioning in GSM power amplifier control loops.
For engineers reviewing the LMV712LDX/NOPB datasheet, LMV712LDX/NOPB pinout, LMV712LDX/NOPB application, or LMV712LDX/NOPB equivalent, key selection criteria include independent shutdown timing (2.2 µs turnon), rail-to-rail output swing within 12 mV of rails at 10 kΩ load, low input offset voltage (≤3 mV), capacitive load tolerance up to 200 pF, and operation across –40°C to 85°C.
Technical Context
The LMV712LDX/NOPB employs parallel NMOS and PMOS input stages with dynamic bias switching to achieve rail-to-rail input common-mode range (–0.2 V to V+ + 0.3 V), while maintaining stable operation across the full range. Its folded-cascode gain stage and Class AB output stage deliver high-speed, low-distortion performance with unity-gain stability.
Independent shutdown pins (SDA, SDB) reduce each channel's supply current to ≤1.5 µA in disabled state, forcing outputs to V− with no glitch during wake-up. The device supports single-supply operation and handles capacitive loads up to 200 pF without external compensation in unity-gain configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 5 MHz - enables stable closed-loop operation up to ~400 kHz with gain ≥12 in non-inverting configuration. |
| Slew rate | 5 V/µs - supports clean 1-MHz, 5-Vpp small-signal output without distortion. |
| Input voltage noise | 20 nV/√Hz at 1 kHz - suitable for low-level sensor amplification where noise floor impacts SNR. |
| Supply current per channel | 1.22 mA typical at 2.7 V - allows dual-channel analog front-end design in battery-powered devices with <2.5 mA total quiescent draw. |
| Input offset voltage | ≤3 mV max at 25°C - ensures ≤0.3% error in 1-V full-scale DC-coupled gain stages. |
| Rail-to-rail output swing | Within 12 mV of V+ and V− at 10 kΩ load - preserves dynamic range in 2.7-V systems requiring >2.6-V peak output. |
| Shutdown current | ≤1.5 µA per channel - reduces system standby power by >99% versus active mode. |
Pinout & Package
LMV712LDX/NOPB is packaged in a 10-pin WSON (NGY) package measuring 3.0 mm × 3.0 mm with exposed thermal pad. Pin 11 (thermal pad) must be connected to V− or left floating per TI layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTA) | Channel A output | Drives external load; rail-to-rail swing supports direct interface to ADC reference or PA bias control node. |
| 2 (–INA) | Channel A inverting input | Accepts feedback network; high impedance (IB ≤115 pA) minimizes resistor-induced offset errors. |
| 3 (+INA) | Channel A noninverting input | Receives signal source; common-mode range extends 0.2 V below V− and 0.3 V above V+. |
| 4 (V−) | Negative supply | Ground reference for single-supply operation; thermal pad connection point for thermal management. |
| 5 (SDA) | Channel A shutdown control | Logic-low (<0.8 V) disables Channel A; output sinks to V− with <200 mV residual voltage. |
| 6 (SDB) | Channel B shutdown control | Independent enable/disable of Channel B; allows staggered wake-up or channel-specific power gating. |
| 7 (+INB) | Channel B noninverting input | Dedicated second channel input; enables differential sensing or dual-path signal processing. |
| 8 (–INB) | Channel B inverting input | Supports separate feedback loop; identical electrical specs to Channel A inputs. |
| 9 (OUTB) | Channel B output | Provides second independent output; matched AC/DC performance to OUTA for balanced designs. |
| 10 (V+) | Positive supply | Accepts 2.7–5.5 V; PSRR ≥70 dB ensures immunity to supply ripple in noisy RF environments. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 2.7-V supply: input accepts signals from –0.2 V to 2.9 V; output swings to within 12 mV of both rails at 10 kΩ. |
| Independent per-channel shutdown | Reduces system idle power by disabling unused channel(s); 2.2 µs turnon ensures glitch-free ramp for PA bias control. |
| 200-pF capacitive load drive | Eliminates need for isolation resistors in most sensor or filter buffer applications, simplifying PCB layout and reducing component count. |
| Low 20-nV/√Hz input voltage noise | Maintains signal integrity in front-end amplification of weak RF detector or microphone signals without degrading SNR. |
| Specified operation from –40°C to 85°C | Validated performance across industrial temperature range, supporting deployment in cellular infrastructure and handheld radios. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV722IDGKR | No shutdown function; 10-pin VSSOP package; 10-MHz GBW; higher 2.3-mA supply current. | Lacks independent channel disable - unsuitable for burst-mode PA control requiring glitch-free wake-up. | Select when higher bandwidth is required and shutdown is unnecessary; verify layout compatibility with VSSOP footprint. |
| TLV2772IDR | Includes shutdown but only single enable pin (not per-channel); 2.5-mA supply current; 4.8-MHz GBW; 16-V max supply. | Shared shutdown limits independent channel power management; higher supply current increases battery drain in portable use. | Choose for cost-sensitive designs where per-channel shutdown is not critical and 5-V operation suffices. |
Compared with LMV712LDX/NOPB, LMV722IDGKR offers higher bandwidth but lacks shutdown capability essential for power-constrained RF control, while TLV2772IDR provides shutdown at the expense of channel independence and higher quiescent current - making LMV712LDX/NOPB optimal for dual-channel, low-glitch, battery-efficient PA biasing.

FAQ
What is the maximum capacitive load the LMV712LDX/NOPB can drive without oscillation?
The LMV712LDX/NOPB can drive up to 200 pF in unity-gain configuration without external compensation or oscillation, as verified in TI's production characterization. This applies to both channels under recommended operating conditions (2.7 V to 5.5 V supply, –40°C to 85°C). Exceeding 200 pF requires an isolation resistor (RISO) per Figure 32 in the LMV712-N datasheet. The LMV712LDX/NOPB maintains phase margin ≥60° at this load.
Does the LMV712LDX/NOPB support true single-supply operation with rail-to-rail inputs?
Yes, the LMV712LDX/NOPB supports true single-supply operation from 2.7 V to 5.5 V with rail-to-rail inputs spanning from (V− − 0.2 V) to (V+ + 0.3 V). At 2.7 V supply, this means inputs operate from –0.2 V to 3.0 V. The internal parallel NMOS/PMOS input stage automatically selects the active pair based on common-mode voltage, ensuring continuous, low-distortion operation across the full range - a key feature confirmed in Section 7.3 of the LMV712-N datasheet.
What is the typical turnon time from shutdown for the LMV712LDX/NOPB?
The LMV712LDX/NOPB has a typical turnon time of 2.2 µs from shutdown to full output functionality at 25°C and 2.7 V supply, as specified in the Electrical Characteristics table (Section 6.5). This value represents the time for the output to settle within 1% of final value after the shutdown pin transitions from logic-low to valid high-enable voltage. DSBGA variants exhibit longer turnon (6 µs), but the LMV712LDX/NOPB uses the WSON package and meets the 2.2-µs spec.
How does the LMV712LDX/NOPB behave during shutdown?
When either shutdown pin (SDA or SDB) is pulled low (<0.8 V), the corresponding amplifier channel disables, reducing its supply current to ≤1.5 µA and forcing its output to V− with ≤200 mV residual voltage. The enabled channel continues normal operation. This behavior is explicitly characterized in Section 7.4.1 and Table 6.5 (VO(SD)). The LMV712LDX/NOPB's glitch-free ramp-up ensures no voltage spike occurs at the output during wake-up - critical for GSM PA control.
Is the LMV712LDX/NOPB qualified for automotive applications?
No, the LMV712LDX/NOPB is not AEC-Q100 qualified. It is the commercial-grade variant (LMV712-N), rated for –40°C to +85°C operation. The automotive-qualified version is the LMV712-N-Q1 (Grade 1, –40°C to +125°C), which carries a different part number and qualification documentation. TI explicitly separates these variants in the Device Information table and Applications section - the LMV712LDX/NOPB datasheet contains no AEC-Q100 test reports or automotive reliability data.
