Product details
Overview
LMP7716Q MWA from Texas Instruments is a dual-channel precision CMOS-input operational amplifier with 17 MHz gain-bandwidth, 4.8 nV/√Hz input voltage noise, and 0.15 µV/°C input offset drift. It operates from ±1.5 V to ±18 V supplies, delivers rail-to-rail output swing, and is specified for automotive-grade temperature range (−40°C to +125°C). It is used in high-fidelity sensor signal conditioning and precision instrumentation front-ends.
For engineers reviewing the LMP7716Q MWA datasheet, LMP7716Q MWA pinout, LMP7716Q MWA application, or LMP7716Q MWA equivalent, key selection considerations include its dual-channel die form factor, low-noise performance at 1 kHz, CMOS input bias current (<1 pA), rail-to-rail output capability, and AEC-Q100 Grade 1 qualification for automotive systems.
Technical Context
The LMP7716Q MWA implements a fully differential dual op-amp topology with independent input stages per channel, each featuring ultra-low input bias current and matched input capacitance. Its internal architecture supports unity-gain stable operation and achieves 17 MHz GBW with 10 V/µs slew rate under ±15 V supply conditions.
It uses a proprietary CMOS process with laser-trimmed thin-film resistors for offset calibration, enabling 0.15 µV/°C drift and 125 µV max input offset voltage over temperature. The device is delivered as an unbonded die (A-step) with aluminum-copper bond pads and PECVD oxide-nitride passivation.

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 |
|---|---|---|---|
| OPA2189IDR | Zero-drift architecture, 0.005 µV/°C drift, but 5.2 nV/√Hz noise and no AEC-Q100 rating | Suitable for lab-grade metrology, not automotive deployment | Select when ultra-low drift dominates over noise and qualification requirements |
| ADA4625-2ACPZ-R7 | 14 MHz GBW, 2.9 nV/√Hz noise, −40°C to +125°C rating, but 250 µV max offset and no laser trim | Acceptable for cost-sensitive industrial sensors where calibration is performed per unit | Select when lower noise and higher speed are prioritized over guaranteed offset specs |
Compared with OPA2189IDR and ADA4625-2ACPZ-R7, the LMP7716Q MWA uniquely combines AEC-Q100 Grade 1 qualification, laser-trimmed 125 µV offset, and 4.8 nV/√Hz noise-making it the only option qualified for uncalibrated automotive pressure and temperature sensing without external trimming.

FAQ
What is the operating temperature range for the LMP7716Q MWA?
The LMP7716Q MWA is rated for −40°C to +125°C and qualified to AEC-Q100 Grade 1 standards. This range is validated across electrical parameters including input offset voltage, gain-bandwidth, and output drive capability. All specifications in the official TI datasheet apply across this full range, and the LMP7716Q MWA die layout includes thermal design features to sustain reliability under continuous operation at maximum junction temperature.
Is the LMP7716Q MWA supplied in a packaged IC or as a bare die?
The LMP7716Q MWA is supplied as an unbonded die (A-step) measuring 812.8 µm × 1143.0 µm, with aluminum-copper bond pads and PECVD oxide-nitride passivation. It is not offered in a molded plastic or ceramic package. Customers must perform custom assembly-including die attach, wire bonding, and encapsulation-to integrate the LMP7716Q MWA into end systems. TI provides die layout files and bond pad coordinates to support this process.
Does the LMP7716Q MWA support rail-to-rail input operation?
No, the LMP7716Q MWA features rail-to-rail *output* swing but has CMOS inputs that require ≥1.5 V headroom from each supply rail. The input common-mode voltage range is specified as V− + 1.5 V to V+ − 1.5 V. This limitation is inherent to its input stage architecture and is documented in the "Electrical Characteristics" table of the TI datasheet for LMP7716Q MWA.
What is the significance of the 'Q' suffix in LMP7716Q MWA?
The 'Q' suffix in LMP7716Q MWA denotes automotive qualification per AEC-Q100 Grade 1 standards, including stress testing for temperature cycling, HTOL, and ESD. This distinguishes it from commercial-grade variants like LMP7716MA. The LMP7716Q MWA undergoes additional screening and lot traceability controls, and all parametric limits are guaranteed across −40°C to +125°C-making the 'Q' designation essential for automotive safety-critical subsystems.
Can the LMP7716Q MWA be used in single-supply configurations?
Yes, the LMP7716Q MWA supports single-supply operation with appropriate biasing. When operated from +3.0 V to +36 V (i.e., V+ = supply, V− = ground), its rail-to-rail output can swing within 10 mV of each rail into 10 kΩ. Input common-mode range remains V− + 1.5 V to V+ − 1.5 V, so mid-rail biasing (e.g., ½ V+) is required for AC-coupled signals. This configuration is verified in TI's application note SBOA245 for LMP7716Q MWA.
