Product details
Overview
LMP7717MAE/NOPB from Texas Instruments is a single-channel, decompensated, precision CMOS-input operational amplifier optimized for high-speed, low-noise signal conditioning in 1.8V–5.5V systems. It delivers 88 MHz gain bandwidth at G = +10, 5.8 nV/√Hz input voltage noise, ±150 µV max input offset voltage, and rail-to-rail output swing within 25 mV of either rail (10 kΩ load), enabling high-fidelity ADC interface and photodiode amplification.
For engineers reviewing the LMP7717MAE/NOPB datasheet, LMP7717MAE/NOPB pinout, LMP7717MAE/NOPB application, or LMP7717MAE/NOPB equivalent, key selection considerations include its minimum stable gain of +10, 100 fA input bias current, −40°C to +125°C operation, SOT-23-5 packaging, and need for external compensation when used below G = +10.
Technical Context
The LMP7717MAE/NOPB employs a decompensated two-pole architecture with dominant pole at 1.6 kHz and second pole at 45 MHz, enabling 88 MHz GBW while maintaining 1.15 mA quiescent current. Its VIP50 CMOS process ensures femtoampere-level input bias current and rail-to-rail output stage with >40 mA sourcing capability at 1.8V.
Stability requires closed-loop gain ≥ +10 (18–20 dB) without external compensation; lead-lag RC networks enable stable operation down to unity gain. Input common-mode range extends to V−, supporting ground-sensing in single-supply configurations, and PSRR exceeds 85 dB across 1.8V–5.5V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 88 MHz at G = +10 - enables high-speed filtering and buffering up to ~8.8 MHz closed-loop bandwidth |
| Input Voltage Noise Density | 5.8 nV/√Hz at 1 kHz - preserves SNR in low-level sensor and photodiode signal chains |
| Input Bias Current | 100 fA max - minimizes DC error in high-impedance transimpedance and leakage-critical circuits |
| Supply Voltage Range | 1.8V to 5.5V - supports direct battery operation (e.g., Li-ion, coin cell) and mixed-voltage systems |

| 3 | Non-Inverting Input (+) | Differential input node; same common-mode limits as Pin 2; includes ground in single-supply operation |
| 4 | Ground / Negative Supply | Reference for V−; must be low-impedance return path for precision performance |
| 5 | Positive Supply | Connects to 1.8V–5.5V supply; bypass with 0.1 µF ceramic capacitor near pin |
Key Features
| Feature | Design Value |
|---|---|
| Decompensated Architecture | Enables 88 MHz GBW at only 1.15 mA supply current-5× bandwidth vs. comparable unity-gain-stable op amps at same power |
| CMOS Input Stage | 100 fA max input bias current allows use with >1 GΩ source impedances without significant DC error |
| Rail-to-Rail Output | Delivers full-scale swing into 10 kΩ loads at 1.8V supply-critical for maximizing resolution in low-voltage SAR ADC drivers |
| Low-Voltage Operation | Specified performance at 1.8V (0°C–125°C) and 2.5V/5V-enables direct integration into energy-constrained IoT sensor nodes |
| High PSRR & CMRR | ≥85 dB PSRR and ≥83 dB CMRR ensure robustness against supply ripple and common-mode interference in noisy industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMP7715MA/NOPB | Unity-gain stable; 17 MHz GBW; 1.3 mA supply current; higher input bias current (200 fA max) | Preferred where simplicity of unity-gain operation outweighs bandwidth requirement | Select when design cannot accommodate external compensation or requires G ≤ +1 without stability risk |
| OPA377AIDBVR | Unity-gain stable; 9 MHz GBW; 760 µA supply current; 0.5 pA input bias current; 7.5 nV/√Hz noise | Better suited for ultra-low-power, lower-bandwidth sensor interfaces | Select when power budget <1 mA is critical and bandwidth ≤ 1 MHz suffices |
Compared with LMP7715MA/NOPB and OPA377AIDBVR, the LMP7717MAE/NOPB provides highest bandwidth per milliamp but requires careful compensation above G = +10-making it optimal for high-fidelity, medium-power signal chains where speed and noise are prioritized over layout simplicity.

FAQ
What is the minimum stable gain for LMP7717MAE/NOPB?
The LMP7717MAE/NOPB is decompensated and requires a minimum closed-loop gain of +10 (20 dB) for unconditional stability without external compensation. Attempting unity-gain or G = +2 configurations without lead-lag RC network will cause oscillation. The datasheet confirms stability margin drops near zero degrees at G < +10 due to second pole at 45 MHz.
Does LMP7717MAE/NOPB support 1.8V operation across its full temperature range?
LMP7717MAE/NOPB is specified for 1.8V operation from 0°C to +125°C. At −40°C to +125°C, minimum supply is 2.0V. This makes it suitable for battery-powered devices that operate above freezing but must survive automotive or industrial thermal cycling up to +125°C.
What package type is used for LMP7717MAE/NOPB?
LMP7717MAE/NOPB uses the 5-pin SOT-23 package (MO-178AA), with pinout: Pin 1 = Output, Pin 2 = Inverting Input, Pin 3 = Non-Inverting Input, Pin 4 = Ground, Pin 5 = V+. No exposed thermal pad is electrically connected; θJA = 180°C/W on standard 2-layer board.
How does the input noise of LMP7717MAE/NOPB compare to similar precision op amps?
LMP7717MAE/NOPB delivers 5.8 nV/√Hz input voltage noise at 1 kHz-lower than OPA377 (7.5 nV/√Hz) and comparable to LMP7715 (6.2 nV/√Hz). Its 0.01 pA/√Hz current noise and 100 fA bias current make it superior for high-Z sources where current noise dominates total noise.
Can LMP7717MAE/NOPB be used as a comparator?
No-LMP7717MAE/NOPB is not designed for open-loop comparator operation. Its rail-to-rail output stage uses positive feedback to boost drive strength, which causes unpredictable propagation delay and latch-up risk when overdriven. TI explicitly advises against using LMP7717MAE/NOPB as a comparator in the datasheet Application Information section.
