Product details
Overview
LMP7716MME/NOPB from Texas Instruments is a dual-channel, rail-to-rail output, precision CMOS operational amplifier optimized for low-noise, low-offset sensor interface and transimpedance applications. It delivers 17 MHz gain bandwidth, ±150 μV max input offset voltage, 5.8 nV/√Hz input voltage noise at 1 kHz, 100 fA typical input bias current, and operates from 1.8 V to 5.5 V supply - enabling high-fidelity signal conditioning in portable medical sensors and battery-powered instrumentation.
For engineers reviewing the LMP7716MME/NOPB datasheet, LMP7716MME/NOPB pinout, LMP7716MME/NOPB application, or LMP7716MME/NOPB equivalent, key selection criteria include its dual-channel VSSOP-8 layout, guaranteed −40°C to +125°C operation, rail-to-rail output swing within 25 mV of rails, and verified performance in transimpedance amplifiers with photodiodes and high-impedance sources.
Technical Context
The LMP7716MME/NOPB employs TI's VIP50 CMOS process to achieve ultra-low input bias current (100 fA) and low input voltage noise (5.8 nV/√Hz), making it suitable for high-impedance source amplification where leakage and noise dominate error budgets. Its dual-channel architecture shares a common supply and substrate but maintains channel isolation via independent input stages and output buffers.
It features rail-to-rail output swing (25 mV from rails at RL = 2 kΩ), wide common-mode input range (−0.3 V to V+ − 0.3 V), and stable unity-gain operation up to 120 pF capacitive load without external compensation. The device supports closed-loop gains ≥1 with phase margin >60° across 1.8–5.5 V supply and full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Input Offset Voltage (max) | ±150 μV at TA = −40°C to +125°C - ensures <0.03% gain error in 5 V full-scale precision measurement systems. |
| Input Voltage Noise Density | 5.8 nV/√Hz at 1 kHz - preserves SNR in low-level analog front-ends such as ECG electrodes or strain gauge bridges. |
| Input Bias Current (typ) | 100 fA - minimizes voltage error across >100 MΩ source impedances, critical for pH probes and piezoelectric sensors. |
| Supply Voltage Range | 1.8 V to 5.5 V - supports direct interfacing with Li-ion (3.0–4.2 V), coin-cell (1.8–3.0 V), and 3.3/5 V logic domains. |
| Rail-to-Rail Output Swing | Within 25 mV of either rail at RL = 2 kΩ - maximizes dynamic range in single-supply systems with limited headroom. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive, industrial control, and outdoor environmental monitoring. |

| 6 | Inverting Input A (−IN A) | High-impedance CMOS input node for Channel A; used with feedback resistor in transimpedance or inverting gain stages. |
| 7 | Output A (OUT A) | Class AB rail-to-rail output identical in drive capability to OUT B; supports independent loading per channel. |
| 8 | Positive Supply (V+) | Single positive supply input (1.8–5.5 V); no negative rail required; decoupling capacitor (0.1 μF) mandatory at pin. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low input bias current | 100 fA typical - reduces DC error in high-Z sensor interfaces (e.g., glass pH electrodes, piezoresistive MEMS) by >10× vs. bipolar op amps. |
| Low input voltage noise | 5.8 nV/√Hz at 1 kHz - enables detection of sub-μV signals in low-frequency biosensors without compromising bandwidth. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2188AIDR | Lower offset (±25 μV max), higher supply current (1.35 mA/ch), wider supply (4.5–36 V), no 1.8 V support | Better DC precision but incompatible with battery-powered 1.8–3.3 V systems; requires dual supply for rail-to-rail input | Select OPA2188AIDR only when ultra-low offset dominates over supply voltage flexibility and power budget. |
| AD8606ARMZ | Higher noise (12 nV/√Hz), lower GBW (10 MHz), same VSSOP-8 package, 2.7–5.5 V supply only | Marginally adequate for audio or medium-speed sensors but insufficient for wideband photodiode or fast-settling instrumentation | Choose AD8606ARMZ only for cost-sensitive, non-critical 2.7 V+ applications where noise and bandwidth are secondary. |
Compared with OPA2188AIDR and AD8606ARMZ, the LMP7716MME/NOPB uniquely balances 1.8 V operation, 17 MHz bandwidth, and 5.8 nV/√Hz noise - making it the only dual VSSOP-8 op amp qualified for high-accuracy, low-voltage, wideband sensing without trade-offs in supply range or noise floor.

FAQ
What is the maximum capacitive load the LMP7716MME/NOPB can drive without oscillation?
The LMP7716MME/NOPB is stable driving up to 120 pF directly at its output in unity-gain follower configuration, as verified in TI's SNOSAV0E datasheet Figure 32. This eliminates the need for isolation resistors in many ADC driver and filter applications. For loads exceeding 120 pF, an RISO resistor (typically 10–100 Ω) between the output and capacitive load restores phase margin without degrading DC accuracy. The LMP7716MME/NOPB's robust stability is enabled by its internal compensation and low output impedance.
Does the LMP7716MME/NOPB support true rail-to-rail input operation?
No, the LMP7716MME/NOPB features rail-to-rail *output* swing but not rail-to-rail *input*. Its input common-mode voltage range extends to −0.3 V below V− (ground) and up to V+ − 0.3 V, as specified in the Electrical Characteristics table. This allows operation with inputs slightly beyond ground in single-supply systems - sufficient for most sensor interfaces - but does not support input voltages equal to V+ or V−. For true rail-to-rail input, consider TI's OPA2333 or similar chopper-stabilized devices.
Is the LMP7716MME/NOPB suitable for transimpedance amplifier designs with photodiodes?
Yes, the LMP7716MME/NOPB is explicitly recommended for transimpedance amplifiers in TI's application notes (Section "TRANSIMPEDANCE AMPLIFIER"). Its 100 fA input bias current prevents signal loss in high-resistance feedback networks, while its 5.8 nV/√Hz voltage noise and 17 MHz GBW preserve bandwidth and SNR for fast photodiode responses. The LMP7716MME/NOPB's low input capacitance (typ. 3.5 pF common-mode) also minimizes peaking when combined with photodiode junction capacitance.
What is the supply current consumption of the LMP7716MME/NOPB at 1.8 V?
At VS = 1.8 V and TA = 25°C, the LMP7716MME/NOPB consumes 1.30 mA per channel (2.60 mA total), as confirmed in the 2.5 V Electrical Characteristics table (IS = 1.30 mA, typ). This value remains stable across the full −40°C to +125°C range, with a maximum of 1.85 mA per channel at temperature extremes. This ultra-low quiescent current enables multi-year battery life in always-on sensor nodes powered by coin cells or energy harvesters.
How does the LMP7716MME/NOPB differ from the automotive-grade LMP7716Q?
The LMP7716MME/NOPB and LMP7716Q share identical electrical specifications, pinout, and package (VSSOP-8), but the LMP7716Q undergoes additional automotive-specific manufacturing controls and reliability testing per AEC-Q100 Grade 1 (−40°C to +125°C). The LMP7716Q includes enhanced defect screening, lot traceability, and qualification for automotive flow processes - while the LMP7716MME/NOPB is rated for commercial/industrial use. Both parts are drop-in compatible in PCB layout and schematic design.
