Product details
Overview
LMP7715MF from Texas Instruments is a single-channel, rail-to-rail output, CMOS-input precision operational amplifier optimized for low-noise, low-offset signal conditioning in portable and sensor interface applications. It delivers 17 MHz gain bandwidth, ±150 μV max input offset voltage, 100 fA input bias current, 5.8 nV/√Hz input voltage noise at 1 kHz, and operates from 1.8 V to 5.5 V supply. Its SOT-23-5 package enables compact instrumentation front-ends.
For engineers reviewing the LMP7715MF datasheet, LMP7715MF pinout, LMP7715MF application, or LMP7715MF equivalent, key selection criteria include its 17 MHz GBW with 1.15 mA supply current, rail-to-rail output swing within 25 mV of either rail, −40°C to 125°C operating temperature range, and suitability for transimpedance amplifiers, active filters, and high-fidelity sensor interfaces requiring sub-200 μV offset and femtoampere-level input bias.
Technical Context
The LMP7715MF uses TI's VIP50 CMOS process to achieve ultra-low input bias current (100 fA) and low input voltage noise (5.8 nV/√Hz), enabling high-impedance source interfacing without significant DC error or SNR degradation. Its rail-to-rail output stage supports full dynamic range in 1.8 V–5.5 V single-supply systems.
It features a unity-gain stable architecture with 17 MHz gain bandwidth product and 6.0–9.5 V/μs slew rate, supporting accurate wideband amplification up to ~10 MHz closed-loop. Input common-mode range extends 300 mV below ground, facilitating true single-supply operation with ground-referenced inputs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Zero-drift architecture; 0.1 μV/°C offset drift vs. LMP7715MF's ±4 μV/°C; 1.2 mA supply current; 350 kHz GBW. | Better long-term DC stability in thermally varying environments; lower bandwidth limits AC signal fidelity. | Select OPA333AIDBVR for ultra-stable DC gain paths (e.g., weigh scales); choose LMP7715MF for wideband sensor signal chains requiring >10 MHz closed-loop bandwidth. |
| ADA4522-1ARMZ | Zero-drift, 2.5 μV max offset, 5.8 nV/√Hz noise, 3 MHz GBW, 1.4 mA supply current, rail-to-rail output. | Superior offset drift (0.005 μV/°C) but lower bandwidth; higher PSRR (140 dB) than LMP7715MF (98 dB). | Select ADA4522-1ARMZ for precision DC measurement where drift dominates error budget; retain LMP7715MF when 17 MHz GBW and 100 fA bias are mandatory for photodiode or high-Z source interfaces. |
Compared with OPA333AIDBVR and ADA4522-1ARMZ, the LMP7715MF uniquely balances 17 MHz bandwidth, 100 fA input bias, and 5.8 nV/√Hz noise in a 5-pin SOT-23 package-making it optimal for wideband, high-impedance sensor interfaces where zero-drift trade-offs in speed or quiescent current are unacceptable.

FAQ
What is the maximum input common-mode voltage range for the LMP7715MF?
The LMP7715MF supports an input common-mode voltage range from −0.3 V (300 mV below ground) to (V+ − 1.2 V) at 5 V supply, and up to V+ − 1.5 V at lower supplies. This allows true single-supply operation with ground-referenced inputs and accommodates signals extending slightly below ground-critical for interfacing with transducers and sensors in unipolar systems. The specification is verified across −40°C to 125°C.
Does the LMP7715MF require external compensation for unity-gain stability?
No, the LMP7715MF is internally compensated and unity-gain stable. It drives capacitive loads up to 120 pF directly without oscillation. For loads exceeding 120 pF, a series isolation resistor (RISO) between the output and load is recommended to maintain phase margin. Stability is confirmed per Figure 32 and Figure 33 in the official SNOSAV0E datasheet for the LMP7715MF.
What is the typical supply current of the LMP7715MF at 1.8 V supply?
The LMP7715MF draws 1.15 mA typical supply current at 5 V, and approximately 0.95 mA at 1.8 V (per Figure 17 in SNOSAV0E). This low quiescent current enables extended battery life in portable instrumentation and IoT edge nodes, while maintaining full 17 MHz gain bandwidth and rail-to-rail output performance across the 1.8 V–5.5 V range.
Can the LMP7715MF drive a 600 Ω load effectively?
Yes-the LMP7715MF delivers ±38 mA output current into a 600 Ω load at 5 V supply (per Electrical Characteristics table, sinking current condition). Its output swing remains within 70 mV of each rail under this load, preserving >90% of full-scale dynamic range. This capability supports line-driving and legacy audio interface requirements without external buffers.
Is the LMP7715MF pin-compatible with other members of the LMP771x family?
No-the LMP7715MF is a single-channel device in 5-pin SOT-23, whereas LMP7716 and LMP7716Q are dual-channel in 8-pin VSSOP. Pin count, pinout, and package are incompatible. Board redesign is required to substitute between LMP7715MF and dual variants; however, electrical specifications (offset, noise, GBW) are closely matched across the family for functional consistency in schematic reuse.
