Product details
Overview
LMP7717MFE/NOPB from Texas Instruments is a 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 photodiode amplification and ADC driver applications.
For engineers reviewing the LMP7717MFE/NOPB datasheet, LMP7717MFE/NOPB pinout, LMP7717MFE/NOPB application, or LMP7717MFE/NOPB equivalent, key selection considerations include its minimum stable gain of +10, 1.15 mA supply current per channel, 100 fA input bias current, −40°C to +125°C operating range, and SOT-23-5 package compatibility with space-constrained sensor front-ends.
Technical Context
The LMP7717MFE/NOPB employs a decompensated two-pole architecture with dominant pole at 1.6 kHz and second pole at 45 MHz, requiring closed-loop gain ≥+10 for unconditional stability. Its VIP50 CMOS process enables femtoampere-level input bias current and rail-to-rail output stage with >40 mA sourcing capability at 1.8V.
It features an input common-mode range extending to the negative rail (ground-sensing), 85–100 dB CMRR over 0–3.7 VCM, and 85–100 dB PSRR across 2.0–5.5 V supply-making it suitable for single-supply, low-voltage instrumentation where DC accuracy and AC fidelity must coexist.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 88 MHz at G = +10 - enables wideband filtering and fast settling in data acquisition front-ends |
| Input Voltage Noise Density | 5.8 nV/√Hz @ 1 kHz - preserves SNR in low-level sensor signals like photodiodes and strain gauges |
| Input Bias Current | 100 fA max - minimizes voltage error across high-impedance sources (e.g., pH electrodes, piezoelectric sensors) |
| Supply Voltage Range | 1.8 V to 5.5 V - supports direct battery operation (Li-ion, coin cell) without regulation overhead |
| Rail-to-Rail Output Swing | 25 mV from rail @ 10 kΩ - maximizes dynamic range in 1.8V/2.5V systems, reducing headroom loss |
| Input Offset Voltage | ±150 µV max - ensures <0.03% gain error in 12-bit precision measurement paths |
| Slew Rate | 35 V/µs (rising) - supports clean 10 VPP signals up to ~5 MHz without distortion |
| Operating Temperature | −40°C to +125°C - qualified for automotive under-hood and industrial motor control environments |
Pinout & Package
The LMP7717MFE/NOPB is housed in a 5-pin SOT-23 package (JEDEC MO-178AA), with thermal resistance θJA = 180°C/W on standard 2-layer PCBs. Pin 1 is marked with a dot; device orientation follows JEDEC standard top view.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Capable of sourcing >40 mA at 1.8V; requires external compensation network when used below G = +10 |
| 2 (−IN) | Inverting input | High-impedance CMOS node; sensitive to layout parasitics-keep trace short and guard with ground |
| 3 (+IN) | Non-inverting input | Common-mode range includes V− (0 V); enables true ground-referenced sensing in single-supply configs |
| 4 (V−) | Negative supply | Connected to ground in single-supply operation; must be decoupled with 0.1 µF ceramic capacitor |
| 5 (V+) | Positive supply | Accepts 1.8–5.5 V; supply rejection remains >85 dB up to 100 kHz for clean analog performance |
Key Features
| Feature | Design Value |
|---|---|
| Decompensated architecture | Enables 88 MHz GBW at only 1.15 mA supply current-5× bandwidth vs. unity-gain-stable LMP7715 at same power |
| Ultra-low input bias current | 100 fA max eliminates leakage-induced offset in high-Z transducer interfaces (e.g., capacitive touch, electret mics) |
| Rail-to-rail output with boost circuit | Delivers >40 mA drive at 1.8V while maintaining 25 mV headroom-critical for driving ADC reference buffers directly |
| Ground-sensing input stage | Input common-mode extends to V−, allowing direct connection of single-ended sensors to ground without level-shifting |
| Low-voltage validated performance | Full electrical specs guaranteed at both 2.5V and 5V; functional down to 1.8V (0°C to 125°C), enabling battery-powered portables |
| VIP50 CMOS process | Provides inherent ESD robustness (2000V HBM) and low 1/f noise corner-ideal for precision DC-coupled measurement chains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA377AIDBVR | Unity-gain stable; 9 MHz GBW; 7 nV/√Hz noise; 0.5 pA IB | Better for G ≤ +1 circuits; lower bandwidth limits high-frequency filter use | Select when simplicity trumps speed-no external compensation needed, but sacrifices >8× bandwidth |
| LMP7715MAX/NOPB | Unity-gain stable; 17 MHz GBW; 6.5 nV/√Hz noise; 20 fA IB | Lower noise floor and bias current, but 5× less bandwidth than LMP7717MFE/NOPB | Prefer for ultra-high-Z, low-frequency (<100 kHz) sensor nodes where stability and lowest IB dominate |
Compared with OPA377AIDBVR and LMP7715MAX/NOPB, the LMP7717MFE/NOPB trades unity-gain stability for 5× higher bandwidth and 2× lower supply current at G = +10-making it optimal for compact, battery-powered, wideband signal chains where external compensation is acceptable.

FAQ
What is the minimum stable gain for LMP7717MFE/NOPB?
The LMP7717MFE/NOPB is decompensated and requires a minimum closed-loop gain of +10 (20 dB) for unconditional stability. Operating at lower gains without external lead-lag compensation risks oscillation due to its second pole at 45 MHz and near-zero phase margin. The datasheet provides RC network design guidance for stable G = +1 operation.
Does LMP7717MFE/NOPB support true single-supply operation with ground-referenced inputs?
Yes. The LMP7717MFE/NOPB features an input common-mode voltage range that includes the negative rail (V−), enabling direct connection of sensors referenced to ground in single-supply configurations. This eliminates the need for level-shifting circuitry in applications such as thermocouple or bridge sensor interfaces powered from 1.8V–5.5V supplies.
What is the maximum output current capability of LMP7717MFE/NOPB at 1.8V supply?
At 1.8V supply, the LMP7717MFE/NOPB can source more than 40 mA and sink up to 21 mA (per datasheet Figure 20/21). This high drive strength-enabled by an internal positive-feedback output stage-allows direct driving of moderate loads like ADC reference buffers or small capacitive filters without external buffering.
How does the input voltage noise of LMP7717MFE/NOPB compare across supply voltages?
The LMP7717MFE/NOPB maintains consistent input voltage noise density: 5.8 nV/√Hz at 5V supply and 6.2 nV/√Hz at 2.5V supply (both measured at 1 kHz). This stability across its 1.8–5.5V operating range ensures predictable SNR in battery-powered systems where supply voltage declines during discharge.
Is LMP7717MFE/NOPB suitable for use as a comparator?
No. The LMP7717MFE/NOPB is not recommended for open-loop comparator operation. Its rail-to-rail output stage uses an active current-boost scheme that compromises phase margin and causes unpredictable response in saturation. Dedicated comparators (e.g., TLV3201) should be used where fast, clean digital edge generation is required.
