Product details
Overview
LMP7716QMMX/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, 5.8 nV/√Hz input voltage noise at 1 kHz, ±150 μV max input offset voltage, and operates from 1.8 V to 5.5 V supply across −40°C to +125°C - enabling high-fidelity signal conditioning in automotive-grade portable instrumentation.
For engineers reviewing the LMP7716QMMX/NOPB datasheet, LMP7716QMMX/NOPB pinout, LMP7716QMMX/NOPB application, or LMP7716QMMX/NOPB equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, dual-channel VSSOP-8 packaging, 100 fA input bias current, rail-to-rail output swing within 25 mV of rails, and verified performance in transimpedance amplifiers driving photodiodes in automotive light-sensing systems.
Technical Context
The LMP7716QMMX/NOPB uses 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 sensor front-ends where leakage and noise dominate error budgets. Its dual-channel architecture supports independent signal paths with matched AC/DC characteristics.
It features rail-to-rail output swing (25 mV from rails at 2 kΩ load), wide common-mode input range (−0.3 V to VS − 0.3 V), and stable unity-gain operation up to 120 pF capacitive load - enabled by internal compensation and robust phase margin design per the datasheet's Figure 32–34.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 17 MHz - enables stable closed-loop operation up to ~10 MHz at moderate gains for wideband sensor signal amplification. |
| Input Voltage Noise Density | 5.8 nV/√Hz @ 1 kHz - preserves SNR in low-level analog front-ends such as photodiode transimpedance stages. |
| Input Bias Current | 100 fA max - minimizes DC error in high-impedance source interfaces (e.g., pH electrodes, piezoresistive sensors). |
| Input Offset Voltage | ±150 μV max - ensures sub-mV DC accuracy without trimming in precision measurement circuits. |
| Supply Voltage Range | 1.8 V to 5.5 V - supports direct integration into single-cell Li-ion (3.0–3.7 V) and 3.3 V/5 V industrial systems. |
| Operating Temperature | −40°C to +125°C - meets automotive under-hood and industrial control ambient requirements. |
| Output Swing | Rail-to-rail, within 25 mV of either supply rail @ 2 kΩ - maximizes dynamic range in low-voltage, single-supply designs. |
| THD+N | 0.001% @ 1 kHz, 4 VPP, RL = 100 kΩ - maintains signal integrity in audio and precision waveform generation paths. |
Pinout & Package
Package: 8-pin VSSOP (Very Small Outline Package), 3.0 mm × 3.0 mm body, 0.65 mm pitch, exposed thermal pad (not electrically connected). RoHS-compliant, lead-free (NOPB suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Delivers rail-to-rail buffered signal; capable of sourcing 46 mA / sinking 10.5 mA at VS = 5 V. |
| 2 (−IN A) | Inverting input A | High-impedance CMOS node; input capacitance ≈ 5 pF (common-mode) - requires careful feedback network design to avoid peaking. |
| 3 (+IN A) | Non-inverting input A | Matches −IN A in bias current and capacitance; supports single-ended or differential input configurations. |
| 4 (V−) | Negative supply rail | Ground reference for single-supply operation or negative rail in split-supply systems; must be low-impedance. |
| 5 (+IN B) | Non-inverting input B | Electrically identical to +IN A; enables dual-channel synchronous sensing or signal processing. |
| 6 (−IN B) | Inverting input B | Matched to −IN A; supports independent feedback networks per channel without crosstalk degradation (typ. >120 dB @ 1 kHz). |
| 7 (OUT B) | Channel B output | Independent output with same drive strength and noise performance as OUT A; no shared internal nodes. |
| 8 (V+) | Positive supply rail | Accepts 1.8–5.5 V; supply current per channel is 1.30 mA typical - total 2.6 mA for dual operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDGKR | Zero-drift architecture; 0.02 μV/°C offset drift vs. LMP7716QMMX/NOPB's ±1.75 μV/°C; higher quiescent current (17 μA vs. 1.3 mA per channel). | Better long-term DC stability in temperature-varying lab equipment; less suitable for wideband (>1 MHz) sensor signals due to chopper-induced artifacts. | Select OPA2333AIDGKR when ultra-low drift dominates over noise and bandwidth requirements. |
| ADA4625-2ACPZ-R7 | Lower input voltage noise (2.9 nV/√Hz), higher GBW (34 MHz), but higher supply current (3.4 mA/channel); not AEC-Q100 qualified. | Superior for high-speed, low-noise data acquisition; unsuitable for automotive production due to lack of automotive qualification and wider temp range mismatch. | Select ADA4625-2ACPZ-R7 for test equipment or industrial DAQ where AEC-Q100 is not required. |
Compared with OPA2333AIDGKR and ADA4625-2ACPZ-R7, the LMP7716QMMX/NOPB uniquely balances 17 MHz bandwidth, 5.8 nV/√Hz noise, 100 fA bias, and AEC-Q100 Grade 1 compliance - making it the only dual-channel option qualified for automotive sensor front-ends requiring both speed and precision.

FAQ
What is the maximum capacitive load the LMP7716QMMX/NOPB can drive without external compensation?
The LMP7716QMMX/NOPB can directly drive up to 120 pF capacitive load in unity-gain follower configuration while maintaining ≥45° phase margin and stable step response, as verified in TI's SNOSAV0E datasheet Figure 32. Exceeding this requires an isolation resistor (RISO) between output and load to restore stability.
Does the LMP7716QMMX/NOPB support true rail-to-rail input common-mode range?
No - the LMP7716QMMX/NOPB supports rail-to-rail *output* swing but has a limited input common-mode range: −0.3 V to VS − 0.3 V. This allows operation 300 mV below ground in single-supply systems but does not extend fully to VS.
Is the LMP7716QMMX/NOPB pin-compatible with other dual op-amps in VSSOP-8 package?
No - the LMP7716QMMX/NOPB has a non-standard pinout (OUT A, −IN A, +IN A, V−, +IN B, −IN B, OUT B, V+) that differs from industry-standard dual op-amps like the LMV722 or OPA2333. PCB layout must follow TI's Figure 4 top view exactly.
What is the typical supply current per channel for the LMP7716QMMX/NOPB at 2.5 V supply?
At VS = 2.5 V and TA = 25°C, the typical supply current per channel is 1.30 mA, as specified in the "5V Electrical Characteristics" table footnote and confirmed in Figure 18. Total device current is ~2.6 mA under these conditions.
How does the LMP7716QMMX/NOPB's AEC-Q100 Grade 1 qualification impact its use in automotive designs?
The LMP7716QMMX/NOPB's AEC-Q100 Grade 1 qualification certifies operation from −40°C to +125°C with enhanced manufacturing controls and reliability testing per automotive standards - enabling direct use in engine control, cabin sensing, and ADAS subsystems without additional qualification overhead.
