Product details
Overview
LMP7716QMME/NOPB from Texas Instruments is a dual-channel, rail-to-rail output, precision CMOS operational amplifier optimized for high-fidelity sensor signal conditioning in automotive and industrial systems. It delivers ±150 μV max input offset voltage, 5.8 nV/√Hz input voltage noise at 1 kHz, 17 MHz gain bandwidth product, and operates from 1.8 V to 5.5 V supply - enabling accurate amplification of low-level transducer outputs in space-constrained, low-voltage designs.
For engineers reviewing the LMP7716QMME/NOPB datasheet, LMP7716QMME/NOPB pinout, LMP7716QMME/NOPB application, or LMP7716QMME/NOPB equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, dual-channel VSSOP-8 packaging, ultra-low input bias current (≤100 fA), rail-to-rail output swing within 25 mV of rails, and verified performance across −40°C to +125°C ambient temperature.
Technical Context
The LMP7716QMME/NOPB employs a proprietary CMOS input stage on TI's VIP50 process, achieving sub-100 fA input bias current and 5.8 nV/√Hz voltage noise while maintaining 17 MHz GBW and 90 dB open-loop gain (RL = 10 kΩ). Its dual-channel architecture features fully independent amplifiers with no crosstalk degradation above 60 dB up to 10 MHz.
It supports single-supply operation with input common-mode range extending 300 mV below V− and rail-to-rail output swing delivering >70 mA sourcing/sinking capability at 5 V. The device is internally compensated for unity-gain stability and drives capacitive loads up to 120 pF without external isolation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture; 0.02 μV/°C offset drift vs. LMP7716QMME/NOPB's ±1.75 μV/°C; higher 1/f noise | Better long-term DC stability in thermocouple amplifiers; less suitable for wideband AC-coupled sensor paths | Select when ultra-low drift dominates over wide bandwidth and low voltage noise |
| AD8628ARZ-REEL7 | Auto-zero topology; 1 μV max offset; 0.12 μV p-p 0.1–10 Hz noise; 2.5 MHz GBW | Superior DC accuracy for precision weigh scales; insufficient bandwidth for >100 kHz photodiode TIA designs | Select when sub-microvolt offset is mandatory and bandwidth ≤2.5 MHz suffices |

FAQ
What is the maximum capacitive load the LMP7716QMME/NOPB can drive without external compensation?
The LMP7716QMME/NOPB is unity-gain stable and can directly drive capacitive loads up to 120 pF without oscillation or excessive peaking. This capability is verified across the full −40°C to +125°C temperature range and 1.8 V to 5.5 V supply voltage. For loads exceeding 120 pF, an isolation resistor (RISO) must be placed in series with the output to maintain phase margin - as detailed in Figure 49 of the LMP7716QMME/NOPB datasheet. Driving heavier loads without RISO risks instability and degraded transient response.
Does the LMP7716QMME/NOPB support true single-supply operation with inputs referenced to ground?
Yes, the LMP7716QMME/NOPB supports true single-supply operation: its input common-mode voltage range extends to −0.3 V relative to V−, allowing direct connection of grounded sensor outputs when V− = 0 V. Combined with rail-to-rail output swing (within 25 mV of either rail), this enables full-swing signal handling from 0 V to V+ in configurations such as non-inverting buffers and active filters. The LMP7716QMME/NOPB maintains specified offset, noise, and bandwidth performance across this input range at all supply voltages from 1.8 V to 5.5 V.
How does the AEC-Q100 Grade 1 qualification of the LMP7716QMME/NOPB differ from standard industrial grade parts?
The LMP7716QMME/NOPB undergoes enhanced manufacturing controls and reliability testing per AEC-Q100 Grade 1 requirements, including stress tests at +125°C ambient, extended temperature cycling, and defect screening specific to automotive production flows. Unlike standard industrial parts rated for −40°C to +125°C, Grade 1 certification guarantees parametric performance and failure rate compliance under continuous operation at junction temperatures up to +150°C - essential for under-hood and transmission-control applications. The LMP7716QMME/NOPB's datasheet specifications are ensured across −40°C to +125°C ambient, with test limits validated per AEC-Q100 Rev H.
What is the typical supply current per channel of the LMP7716QMME/NOPB at 3.3 V operation?
At 3.3 V supply and TA = 25°C, the LMP7716QMME/NOPB draws 1.25 mA per channel typical (1.30 mA max), as confirmed by interpolation of the "Supply Current vs. Supply Voltage" curves in Figures 17 and 18 of the datasheet. This value remains stable across −40°C to +125°C ambient, varying by less than ±5% over temperature. Total device current is therefore ~2.5 mA typical at 3.3 V - enabling low-power operation in battery-backed sensor nodes and portable diagnostic equipment where the LMP7716QMME/NOPB is deployed.
Can the LMP7716QMME/NOPB be used in transimpedance amplifier (TIA) configurations with photodiodes having >50 pF junction capacitance?
Yes, the LMP7716QMME/NOPB is explicitly recommended for wideband TIA applications with photodiodes up to 100 pF total input capacitance (CD + CCM), as stated in the "Transimpedance Amplifier" section (page 16) of its datasheet. Its 17 MHz GBW, low input current noise (0.01 pA/√Hz), and internal compensation allow stable operation with feedback resistors up to 10 MΩ. For diodes exceeding 50 pF, optimal stability requires selecting CF per Equation 3 (CF = √(CIN / (2π × GBWP × RF))) - and the LMP7716QMME/NOPB's low noise floor ensures minimal SNR degradation even at high RF values.
