Product details
Overview
LMP7717MFX/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 ADC interface and photodiode amplification.
For engineers reviewing the LMP7717MFX/NOPB datasheet, LMP7717MFX/NOPB pinout, LMP7717MFX/NOPB application, or LMP7717MFX/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 LMP7717MFX/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 100 fA input bias current and rail-to-rail output stage capable of sourcing >40 mA at 1.8V.
It features ground-sensing input common-mode range (down to V−), 85–100 dB CMRR over 0–3.7 VCM, and 85–100 dB PSRR across 2.0–5.5 V+, supporting precision single-supply operation in low-voltage instrumentation without level-shifting circuitry.
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 stages |
| 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 leakage-induced offset in high-impedance transimpedance amplifiers |
| Supply Voltage Range | 1.8V to 5.5V - supports direct battery operation (e.g., Li-ion, coin cell) and mixed-voltage systems |
| Rail-to-Rail Output Swing | 25 mV from rail (10 kΩ) - maximizes dynamic range at low supply voltages like 2.5V or 1.8V |
| Input Offset Voltage | ±150 µV max - ensures <0.01% 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 |

Pinout & Package
Package: 5-pin SOT-23 (small-outline transistor), footprint-compatible with industry-standard SC-70-5 and TSOP-5 variants; thermal resistance θJA = 180°C/W on 2-layer PCB.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output | Amplified signal output; rail-to-rail swing, capable of sourcing 46 mA (min) at 5V |
| 2 | Inverting Input (−) | Differential input node; accepts common-mode voltage down to V− (ground in single-supply) |
| 3 | Non-Inverting Input (+) | Differential input node; matched impedance to Pin 2 for optimal CMRR |
| 4 | Ground / Negative Supply | Reference return path; must be low-impedance for noise immunity and stability |
| 5 | Positive Supply | Power input; bypassing with 0.1 µF ceramic capacitor to Pin 4 is mandatory for stability |

FAQ
What is the minimum stable gain for the LMP7717MFX/NOPB?
The LMP7717MFX/NOPB is decompensated and requires a minimum closed-loop gain of +10 (20 dB) for unconditional stability. Operating below this gain risks oscillation unless external lead-lag compensation (RC network) is added. This is confirmed in the TI datasheet SNOSAY7H Section "Using the Decompensated LMP7717" and Figure 48's phase margin analysis.
Does the LMP7717MFX/NOPB support true rail-to-rail input?
No-the LMP7717MFX/NOPB features rail-to-rail *output* swing but only ground-sensing *input* common-mode range (down to V−). Its input common-mode voltage extends to −0.3 V (below V−) and up to 4 V at 5 V supply, as specified in the 5V Electrical Characteristics table. It does not support input voltages at the positive rail.
Can the LMP7717MFX/NOPB operate from a 1.8V supply?
Yes-the LMP7717MFX/NOPB is fully specified and ensured functional at 1.8V supply for temperatures from 0°C to 125°C, and at 2.0–5.5V across −40°C to 125°C. Key parameters including GBW (88 MHz), noise (5.8 nV/√Hz), and output swing (25 mV from rail @ 10 kΩ) are validated at 1.8V per the Operating Ratings and 2.5V Electrical Characteristics tables.
What is the maximum output current capability of the LMP7717MFX/NOPB?
The LMP7717MFX/NOPB can source up to 46 mA (min) and sink up to 10.5 mA (min) at 5V supply, as specified in the 5V Electrical Characteristics table under "Output Short Circuit Current." At 1.8V, it maintains >40 mA sourcing capability-critical for driving heavy capacitive loads or low-impedance ADC inputs without external buffers.
Is the LMP7717MFX/NOPB suitable for photodiode transimpedance applications?
Yes-the LMP7717MFX/NOPB is explicitly recommended for photodiode amplifiers in its Applications section. Its 100 fA input bias current, 5.8 nV/√Hz voltage noise, low input capacitance (~0.2 pF), and decompensated bandwidth make it ideal for high-gain, low-noise TIA designs-as demonstrated in Figure 1 of the datasheet.
