Product details
Overview
LMV712TL/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 rail-to-rail operation from 2.7 V to 5.5 V - enabling precision signal conditioning in GSM power amplifier control loops.
For engineers reviewing the LMV712TL/NOPB datasheet, LMV712TL/NOPB pinout, LMV712TL/NOPB application, or LMV712TL/NOPB equivalent, this page provides verified specifications, package mapping (10-pin WSON), functional pin definitions, real-world use cases in RF front-end control, and validated alternative options for design continuity.
Technical Context
The LMV712TL/NOPB employs parallel NMOS/PMOS input stages to achieve rail-to-rail input common-mode range, with internal logic dynamically allocating bias current across VCM to maintain stability. Its output stage uses a PMOS–NPN composite configuration to deliver true rail-to-rail swing up to 200 pF capacitive load without oscillation in unity-gain configuration.
Independent shutdown pins (SDA, SDB) reduce each channel's supply current to ≤1.5 µA while holding the output at V−; turnon time is 1.6 µs (typ.) at 5 V with glitch-free ramping - critical for avoiding transients in PA bias control paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 5 MHz - supports stable closed-loop gain up to 10× at 500 kHz in battery-powered RF monitoring circuits. |
| Slew rate | 5 V/µs - enables clean amplification of fast-settling control signals in GSM/EDGE PA envelope tracking. |
| Input voltage noise | 20 nV/√Hz at 1 kHz - preserves SNR in low-level detector and feedback path conditioning. |
| Supply current per channel | 1.22 mA (typ. at 5 V) - allows dual-channel operation within tight 2.5 mA total budget for handheld RF modules. |
| Input offset voltage | ≤3 mV (max) - ensures <±10 mV error in 0–2.5 V PA bias control range without trimming. |
| Rail-to-rail I/O | Operates with VCM = V− to V+ and VOUT = V− to V+ - eliminates level-shifting in single-supply 2.7–5.5 V systems. |
| Shutdown current | ≤1.5 µA per channel - enables dynamic power gating during TX/RX idle periods in burst-mode wireless transceivers. |
Pinout & Package
LMV712TL/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 recommendation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTA) | Channel A output | Drives PA bias node; rail-to-rail swing ensures full DAC output utilization in closed-loop control. |
| 2 (–INA) | Channel A inverting input | Accepts feedback from directional coupler detector output in PA control loop. |
| 3 (+INA) | Channel A noninverting input | Receives reference voltage from DAC or bandgap source for precise setpoint comparison. |
| 4 (V−) | Negative supply input | Ground reference for single-supply operation; connects to thermal pad for improved thermal performance. |
| 5 (SDA) | Channel A shutdown | Active-low enable: ≤0.8 V disables Channel A, reducing ICC to ≤1.5 µA and forcing OUTA to V−. |
| 6 (SDB) | Channel B shutdown | Independent control for second channel - enables selective channel gating in dual-PA or diversity architectures. |
| 7 (+INB) | Channel B noninverting input | Supports auxiliary functions such as temperature-compensated bias or RSSI monitoring. |
| 8 (–INB) | Channel B inverting input | Configurable for differential sensing or secondary feedback path in multi-stage control. |
| 9 (OUTB) | Channel B output | Provides redundant or complementary control signal; shares same GBW and noise specs as OUTA. |
| 10 (V+) | Positive supply input | Accepts 2.7–5.5 V regulated supply; PSRR ≥70 dB minimizes supply ripple coupling into control path. |
Key Features
| Feature | Design Value |
|---|---|
| Independent shutdown per channel | Enables granular power management: one channel can remain active for monitoring while the other is gated during sleep cycles. |
| Glitch-free turnon (1.6 µs) | Prevents transient spikes on PA bias line that would cause RF output discontinuity or spectral regrowth in GSM transmission. |
| 200 pF capacitive load drive | Eliminates need for external isolation resistors when driving typical PCB trace + detector diode capacitance in RF front ends. |
| Rail-to-rail input common-mode range | Supports direct connection to 0–2.7 V DAC outputs or battery-sensed voltages without external level shifters. |
| Low 20 nV/√Hz noise at 1 kHz | Maintains signal integrity in high-gain detector amplifier stages where noise directly impacts RSSI accuracy. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV722QDR | No shutdown pins; higher 1.8 mA/channel supply current; identical GBW, noise, and rail-to-rail I/O. | Lacks independent channel disable - unsuitable for burst-mode PA control requiring glitch-free activation. | Select when shutdown functionality is unnecessary and lower quiescent current is not required. |
| OPA2314AIDR | Lower 0.15 mA/channel supply current; 3 MHz GBW; no guaranteed 200 pF capacitive load drive. | Optimized for ultra-low power sensor interfaces, not RF PA control requiring fast settling and heavy load drive. | Select for always-on battery sensors where speed and capacitive drive are secondary to current draw. |
Compared with LMV712TL/NOPB, LMV722QDR offers identical AC performance but lacks shutdown capability essential for GSM TX burst control, while OPA2314AIDR trades bandwidth and load drive for lower current - making LMV712TL/NOPB the only option meeting all three requirements: speed, drive strength, and dynamic power gating.

FAQ
What is the maximum capacitive load the LMV712TL/NOPB can drive without external compensation?
The LMV712TL/NOPB is specified to drive up to 200 pF in unity-gain configuration without oscillation. This is validated across temperature and supply voltage ranges per TI's Electrical Characteristics table. For loads exceeding 200 pF, TI recommends adding an isolation resistor (RISO) between the output and capacitive node - as shown in Figure 32 of the LMV712TL/NOPB datasheet - to restore phase margin. The LMV712TL/NOPB's internal compensation is optimized for this tolerance, eliminating need for external capacitors in most RF detector and PA bias applications.
Does the LMV712TL/NOPB support true rail-to-rail input and output operation at 2.7 V supply?
Yes. The LMV712TL/NOPB guarantees rail-to-rail input common-mode range (V− to V+) and rail-to-rail output swing (within 120 mV of rails at 600 Ω load) at 2.7 V supply, as confirmed in Section 6.5 of the datasheet. At V+ = 2.7 V and V− = 0 V, the output reaches 2.52 V (high) and 0.05 V (low) into 600 Ω - sufficient to fully utilize 0–2.5 V DAC references or drive MOSFET gate thresholds in low-voltage PA control. Input stage operation remains linear down to V− −0.2 V and up to V+ +0.3 V, ensuring robustness against PCB trace offsets.
What is the typical turnon time from shutdown for the LMV712TL/NOPB at 5 V supply?
The typical turnon time from shutdown for the LMV712TL/NOPB is 1.6 µs at 5 V supply and 25°C, with a maximum of 4 µs over temperature (−40°C to 125°C). This value applies to both channels independently and is measured from the rising edge of the shutdown pin (SDA or SDB) to 90% of final output voltage. The LMV712TL/NOPB features glitch-free ramping - no overshoot or undershoot - which is critical in PA bias control to prevent RF output discontinuities. Datasheet Figure 29 confirms this behavior under 5 V conditions.
How does the LMV712TL/NOPB handle input offset voltage variation across common-mode voltage?
The LMV712TL/NOPB exhibits a crossover in input offset voltage (VOS) near 1.4 V above V−, due to its dual-input-stage architecture (NMOS + PMOS pairs). As shown in Figure 3 of the datasheet, VOS shifts polarity and magnitude across VCM, ranging from +100 µV to −300 µV. For precision applications, designers should avoid operating the LMV712TL/NOPB with input signals centered at the crossover point. Instead, bias inputs toward V− or V+ to stabilize VOS - e.g., using a 0.5 V reference for Channel A in PA control keeps VOS near +150 µV (typ.), well within the 3 mV max spec.
Is the LMV712TL/NOPB pin-compatible with other packages in the LMV712 family?
No. The LMV712TL/NOPB uses the 10-pin WSON (NGY) package, which has a different pinout than the 10-pin DSBGA (YPA) and 10-pin VSSOP (DGS) variants. While all share identical electrical functionality and pin naming (e.g., OUTA, SDA, V+), physical pin assignments differ: WSON places V− on Pin 4 and V+ on Pin 10, whereas VSSOP places V− on Pin 4 and V+ on Pin 10 but rotates IN/OUT positions. PCB layout is not interchangeable. The LMV712TL/NOPB datasheet explicitly lists NGY as its sole package variant - confirming no pin-to-pin compatibility with YPA or DGS versions without board redesign.
