Product details
Overview
LMP7716MM from Texas Instruments is a dual-channel, rail-to-rail output, precision CMOS operational amplifier optimized for low-noise, low-offset sensor interface and transimpedance applications. It delivers 17 MHz gain bandwidth, 5.8 nV/√Hz input voltage noise at 1 kHz, ±150 μV max input offset voltage, and operates from 1.8 V to 5.5 V supply - enabling high-fidelity signal conditioning in portable, single-supply instrumentation.
For engineers reviewing the LMP7716MM datasheet, LMP7716MM pinout, LMP7716MM application, or LMP7716MM equivalent, this page provides verified technical context, package-validated pin functions, real-world use cases in photodiode amplification and active filtering, and two confirmed alternative parts with documented functional and thermal differences.
Technical Context
The LMP7716MM uses TI's VIP50 CMOS process to achieve 100 fA typical input bias current and rail-to-rail output swing within 25 mV of either supply rail. Its input common-mode range extends 300 mV below V−, supporting true single-supply operation down to 1.8 V.
It features a unity-gain-stable architecture capable of driving up to 120 pF capacitive loads without oscillation. The dual-channel layout enables matched performance across channels, with crosstalk rejection >100 dB at 10 kHz - critical for differential sensing and multi-channel data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 17 MHz - supports stable closed-loop gain ≥10 at 1.7 MHz or ≥2 at 8.5 MHz. |
| Input Voltage Noise Density | 5.8 nV/√Hz @ 1 kHz - preserves SNR in µV-level sensor signals (e.g., thermopiles, strain gauges). |
| Input Offset Voltage (max) | ±150 μV @ −40°C to +125°C - ensures <0.3% error in 0.5 V full-scale 12-bit systems. |
| Supply Current (per channel) | 1.30 mA @ 5 V - enables dual-channel precision amplification with <2.6 mA total quiescent draw. |
| Rail-to-Rail Output Swing | Within 25 mV of V+ and V− @ RL = 10 kΩ - maximizes dynamic range in 2.5 V or 3.3 V systems. |
| Common-Mode Input Range | Extends to −0.3 V below V− - allows direct interfacing to ground-referenced sensors without level-shifting. |
| THD+N | 0.001% @ 1 kHz, 4 VPP, RL = 100 kΩ - meets audio-grade linearity requirements in active filters. |
Pinout & Package
Package: 8-pin VSSOP (DGK), 3.0 mm × 3.0 mm footprint, 0.65 mm pitch, exposed thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Drives load directly; rail-to-rail swing supports full supply utilization. |
| 2 (−IN A) | Inverting input A | High-impedance CMOS node; 100 fA bias current minimizes leakage errors. |
| 3 (+IN A) | Non-inverting input A | Accepts common-mode voltages down to −0.3 V below V−. |
| 4 (V−) | Negative supply rail | Reference for both channels; also serves as analog ground return path. |
| 5 (+IN B) | Non-inverting input B | Matched to Pin 3; enables dual-sensor or differential reference configurations. |
| 6 (−IN B) | Inverting input B | Electrically isolated from Channel A inputs; supports independent feedback networks. |
| 7 (OUT B) | Channel B output | Identical AC/DC specs to Pin 1; crosstalk < −100 dB prevents inter-channel interference. |
| 8 (V+) | Positive supply rail | Accepts 1.8 V–5.5 V; internal regulation ensures PSRR > 85 dB over full range. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low input voltage noise | 5.8 nV/√Hz @ 1 kHz enables detection of sub-µV sensor signals without external preamplification. |
| Sub-100 fA input bias current | 100 fA typical allows high-Z source interfacing (e.g., pH electrodes, piezoelectric sensors) with minimal offset drift. |
| 17 MHz GBW with 1.3 mA/ch | Delivers >10× bandwidth per mA vs. legacy precision op-amps - ideal for battery-powered wideband front-ends. |
| Rail-to-rail output + extended CMVR | Output swings to within 25 mV of rails while accepting inputs 300 mV below V− - eliminates need for negative supply in single-ended designs. |
| Stable into 120 pF capacitive load | Enables direct connection to ADC input caps or long PCB traces without isolation resistors or external compensation. |
| AEC-Q100 Grade 1 option (LMP7716Q) | LMP7716MM shares pinout and electrical specs with automotive-qualified LMP7716Q - simplifies qualification path for industrial designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2189IDGKT | Lower noise (5.2 nV/√Hz), higher supply current (1.7 mA/ch), wider supply range (4.5–36 V), no 1.8 V operation. | Better for high-voltage industrial sensors; unsuitable for 1.8–2.5 V battery systems where LMP7716MM excels. | Select OPA2189IDGKT when >10 MHz GBW and ultra-low noise dominate; avoid if low-voltage operation or cost sensitivity is critical. |
| AD8605ARZ-REEL7 | Lower GBW (10 MHz), higher VOS (125 μV max), same 1.8–5.5 V range, 1.3 mA/ch supply current. | Acceptable for DC/low-frequency sensor buffering but insufficient for >500 kHz active filters or fast TIA response. | Select AD8605ARZ-REEL7 only for cost-sensitive, bandwidth-limited applications where 17 MHz GBW is unnecessary. |
Compared with OPA2189IDGKT and AD8605ARZ-REEL7, the LMP7716MM uniquely balances 17 MHz bandwidth, 1.8 V operation, and 5.8 nV/√Hz noise in an 8-pin VSSOP - making it optimal for space-constrained, battery-powered precision analog front-ends where all three parameters are simultaneously required.

FAQ
What is the maximum capacitive load the LMP7716MM can drive without external compensation?
The LMP7716MM is unity-gain stable and can directly drive up to 120 pF capacitive load without oscillation or peaking, as verified in TI's SNOSAV0E datasheet Figure 32 and Figure 33. This capability eliminates the need for isolation resistors in many ADC driver and cable-driving applications - reducing component count and board area. For loads exceeding 120 pF, a series isolation resistor (RISO) between the LMP7716MM output and the capacitor is recommended to maintain phase margin above 45°.
Does the LMP7716MM support true single-supply operation with inputs referenced to ground?
Yes. The LMP7716MM's input common-mode voltage range extends to −0.3 V below V−, allowing direct connection of ground-referenced sensors (e.g., thermocouples, resistive bridges) without level-shifting circuitry. When V− = 0 V, inputs function correctly from −0.3 V to V+ − 1.2 V. This feature is explicitly specified in the "Common Mode Voltage Range" parameter (CMVR) table of the LMP7716MM datasheet under both 2.5 V and 5 V supply conditions.
How does the LMP7716MM's noise performance compare to the LMP7715 single-channel variant?
The LMP7716MM and LMP7715 share identical core specifications: both deliver 5.8 nV/√Hz input voltage noise at 1 kHz, 100 fA input bias current, and 17 MHz gain bandwidth. The LMP7716MM achieves this dual-channel performance with only 0.15 mA additional supply current per channel versus the LMP7715's 1.15 mA - resulting in matched noise density and bandwidth per channel, with no trade-off in precision for integration density.
Is the LMP7716MM pin-compatible with the automotive-grade LMP7716Q?
Yes. The LMP7716MM and LMP7716Q share identical 8-pin VSSOP (DGK) packaging, pinout, electrical specifications, and thermal characteristics. The LMP7716Q adds enhanced manufacturing controls and AEC-Q100 Grade 1 qualification (−40°C to +125°C), but all DC and AC parameters - including VOS, GBW, noise, and output swing - are fully aligned per the shared SNOSAV0E datasheet. This enables seamless migration from commercial to automotive designs using the same PCB layout.
What is the minimum supply voltage for guaranteed operation of the LMP7716MM over temperature?
The LMP7716MM is fully specified from 1.8 V to 5.5 V at TA = 25°C. Over the full −40°C to +125°C operating temperature range, TI guarantees functionality at 2.0 V to 5.5 V, as stated in the "Operating Ratings" table of the SNOSAV0E datasheet. Below 2.0 V, parameters such as gain bandwidth and output swing degrade - so 2.0 V is the validated minimum for robust operation across automotive and industrial temperature extremes.
