Product details
Overview
LMP7717MAE 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 ADC interface and photodiode amplification.
For engineers reviewing the LMP7717MAE datasheet, LMP7717MAE pinout, LMP7717MAE application, or LMP7717MAE equivalent, key selection considerations include its minimum stable gain of +10, 1.15 mA supply current per channel, −40°C to 125°C operating range, and SOT-23-5 package compatibility with space-constrained low-voltage sensor front-ends.
Technical Context
The LMP7717MAE 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 100 fA typical input bias current and rail-to-rail output stage with >40 mA sourcing capability at 1.8V.
It supports single-supply operation from 1.8V with guaranteed performance at 2.5V and 5.0V, features input common-mode range extending to V−, and exhibits 0.04% THD+N at 1 kHz into 600 Ω - making it suitable for precision analog signal chains where noise, offset, and dynamic range are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 88 MHz at G = +10 - enables wideband filtering and buffering without sacrificing DC precision |
| Input Voltage Noise Density | 5.8 nV/√Hz at 1 kHz - preserves SNR in low-level sensor and photodiode applications |
| Input Offset Voltage (max) | ±150 µV - ensures <0.03% error in 5V full-scale instrumentation amplifiers |
| Supply Current (typ) | 1.15 mA - allows battery-powered designs with >10-year runtime at µA-level sleep currents |
| Rail-to-Rail Output Swing | 25 mV from rail (10 kΩ) - maximizes dynamic range in 1.8V–3.3V data acquisition systems |
| Input Bias Current (max) | 100 fA - prevents leakage-induced errors in high-impedance pH, piezo, or MEMS sensor interfaces |
| Operating Temperature Range | −40°C to 125°C - qualified for automotive under-hood and industrial motor control environments |
Pinout & Package
The LMP7717MAE is housed in a 5-pin SOT-23 package (JEDEC MO-178AA), with exposed pad for thermal enhancement and compact PCB footprint (2.9 mm × 1.6 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Drives loads down to 2 kΩ with rail-to-rail swing; requires external compensation for G < +10 |
| 2 - IN− | Inverting input | High-impedance CMOS node; connects to feedback network in standard configurations |
| 3 - IN+ | Non-inverting input | Accepts signals from 0 V (V−) to V+ − 0.3 V; enables ground-referenced single-supply sensing |
| 4 - V− | Negative supply | Typically connected to GND in single-supply use; sets lower common-mode limit |
| 5 - V+ | Positive supply | Accepts 1.8V–5.5V; internal regulation ensures consistent GBW and noise across voltage range |
Key Features
| Feature | Design Value |
|---|---|
| Decompensated architecture | Enables 5× higher bandwidth than unity-gain-stable equivalents (e.g., LMP7715) without increased power |
| CMOS input stage | Delivers femtoampere bias current essential for ultra-high-Z sensor interfacing without guard traces |
| Rail-to-rail output with boost | Sources >40 mA at 1.8V - eliminates need for external output buffers in driving ADC reference drivers |
| Guaranteed 2.5V/5.0V performance | Ensures full spec compliance across battery discharge curves and dual-rail industrial supplies |
| VIP50 process technology | Provides superior PSRR (≥85 dB) and CMRR (≥85 dB) for noisy mixed-signal PCB 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; same SOT-23-5 package | Preferred where G ≤ +1 is required without external compensation components | Select when design cannot accommodate RC compensation network or requires simpler layout |
| OPA377AIDBVR | Unity-gain stable; 9 MHz GBW; 0.76 mA supply current; 5.8 nV/√Hz noise; SOT-23-5 | Better suited for low-power, moderate-bandwidth applications with tighter supply budgets | Choose when 88 MHz bandwidth is unnecessary and quiescent current must be minimized below 1 mA |
Compared with LMP7715MA/NOPB and OPA377AIDBVR, the LMP7717MAE trades unity-gain stability for 5× higher bandwidth and identical noise-making it optimal for high-speed precision signal chains where external compensation is acceptable and layout space permits.

FAQ
What is the minimum stable gain for the LMP7717MAE?
The LMP7717MAE 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 phase margin erosion near the second pole at 45 MHz. The LMP7717MAE datasheet provides RC network design guidance for unity-gain use cases.
Does the LMP7717MAE support true rail-to-rail input operation?
The LMP7717MAE features rail-to-rail *output* swing but only extends its input common-mode range to the negative rail (V−). The positive end is limited to V+ − 0.3 V. This allows ground-referenced sensing in single-supply configurations but prohibits direct connection of signals near V+ without attenuation or level shifting.
Can the LMP7717MAE operate from a 1.8V supply across the full temperature range?
The LMP7717MAE is fully specified and tested for operation at 1.8V supply within 0°C to 125°C. At −40°C to 0°C, minimum supply is 2.0V. All key parameters-including GBW, noise, and offset-remain guaranteed across this extended low-voltage window, enabling energy-harvesting and coin-cell-powered designs.
What package type is used for the LMP7717MAE part number?
The LMP7717MAE uses the 5-pin SOT-23 package (JEDEC MO-178AA), measuring 2.9 mm × 1.6 mm with 0.95 mm height. It features an exposed thermal pad on the bottom for enhanced heat dissipation and is compatible with standard reflow soldering profiles per TI SNOA549.
How does the LMP7717MAE compare to the LMP7718 in terms of supply current?
The LMP7717MAE draws 1.15 mA typical supply current per amplifier, while the dual-channel LMP7718 draws 1.30 mA per channel (2.60 mA total). Both share identical per-channel specifications-noise, offset, GBW, and output drive-making the LMP7717MAE optimal for single-channel, space- and power-constrained applications.
