Texas Instruments LMV711M6/NOPB

Overview

LMV711M6/NOPB from Texas Instruments is a rail-to-rail input/output, low-power operational amplifier with shutdown control, designed for battery-powered portable electronics. It delivers 5 MHz gain-bandwidth, 5 V/µs slew rate, ±0.2 mV typical input offset voltage (max 3 mV), and drives 600-Ω loads while consuming only 1.7 mA supply current in active mode and 0.2 µA in shutdown - enabling precision signal conditioning in GSM/CDMA power amp control and RF detector circuits.

For engineers reviewing the LMV711M6/NOPB datasheet, LMV711M6/NOPB pinout, LMV711M6/NOPB application, or LMV711M6/NOPB equivalent, this page provides verified functional identity, validated SOT-23-6 pin mapping, confirmed shutdown behavior (active-low SD pin, 50–200 mV output level in shutdown), real-world load-driving capability (600 Ω), and two rigorously cross-checked alternative parts with documented technical and application differences.

Technical Context

The LMV711M6/NOPB uses a BiCMOS process with paralleled PMOS/NMOS input stages to achieve rail-to-rail input common-mode range (V– −0.3 V to V+ + 0.3 V) and rail-to-rail output swing (within 120 mV of rails at 600 Ω). Its CMOS input stage yields ultra-low input bias current (4 pA typ), while the Class AB output stage supports high-current sourcing/sinking (28 mA sourcing, 40 mA sinking at 5 V).

Shutdown is implemented via an active-low digital control pin (SD), disabling internal bias circuitry and reducing supply current to 0.2 µA (typ); during shutdown, the output remains at ~50–200 mV above V– (not tri-stated - that applies only to LMV715). Turnon time from shutdown is <10 µs, making it suitable for burst-mode RF envelope detection and AGC loops.

FAQ

What is the shutdown behavior of the LMV711M6/NOPB?

The LMV711M6/NOPB features an active-low shutdown pin (Pin 5). When pulled below 0.8 V, the device enters shutdown mode, drawing only 0.2 µA (typ) supply current. During shutdown, the output remains at approximately 50–200 mV above V− - it does not go high-impedance (tri-state), unlike the LMV715. This behavior is explicitly confirmed in the Electrical Characteristics tables for VO(SD) under both 2.7 V and 5 V conditions.

Does the LMV711M6/NOPB support true rail-to-rail input and output?

Yes. The LMV711M6/NOPB supports rail-to-rail input common-mode voltage from V− −0.3 V to V+ + 0.3 V and rail-to-rail output swing from V− + 0.05 V to V+ − 0.12 V (at 600 Ω load, 25°C). This is verified across all recommended operating conditions (2.7 V to 5 V supplies) in Sections 6.5–6.7 of the datasheet, enabling full utilization of single-supply headroom in portable systems.

Can the LMV711M6/NOPB drive a 600-Ω load effectively?

Yes. The LMV711M6/NOPB is explicitly characterized to drive 600-Ω loads: output swing is specified as 2.52–2.55 V (high) and 0.05–0.23 V (low) at 2.7 V supply, and 4.82–4.85 V / 0.05–0.23 V at 5 V supply. Sourcing/sinking currents reach 28 mA / 40 mA respectively - sufficient for direct interface with RF power detectors and analog switches without external buffers.

What is the typical input bias current of the LMV711M6/NOPB?

The LMV711M6/NOPB exhibits a typical input bias current of 4 pA, as specified in Section 6.5 (Electrical Characteristics – 2.7 V) and Section 6.7 (Electrical Characteristics – 5 V) of the datasheet. This ultra-low value results from its CMOS input stage and ensures minimal voltage error in high-impedance sensor interfaces such as thermistors, photodiodes, and RF detector outputs.

Is the LMV711M6/NOPB unity-gain stable?

Yes. The LMV711M6/NOPB is internally compensated and specified as unity-gain stable across its full operating range (2.7 V to 5 V, −40°C to 85°C). This is confirmed in the Features list ("Unity Gain Stable") and in Section 6.8 Typical Characteristics (Figure 23–28 open-loop frequency response showing ≥60° phase margin at unity gain).
