Product details
Overview
OPA2376AQDRQ1 from Texas Instruments is a dual-channel, AEC-Q100 Grade 1 qualified precision operational amplifier optimized for automotive battery-powered systems. It delivers 7.5 nV/√Hz input voltage noise at 1 kHz, 5 μV typical input offset voltage, 5.5 MHz gain-bandwidth product, and 760 μA typical quiescent current per channel while operating from 2.2 V to 5.5 V single supply. It serves as a rail-to-rail input/output signal conditioner in high-accuracy sensor front-ends and BMS voltage monitoring circuits.
For engineers reviewing the OPA2376AQDRQ1 datasheet, OPA2376AQDRQ1 pinout, OPA2376AQDRQ1 application, or OPA2376AQDRQ1 equivalent, this page provides verified technical context, package-specific pin functions, real-world application mappings, and validated alternative options for automotive-grade precision amplification where low noise, tight dc accuracy, and thermal stability across –40°C to +125°C are mandatory.
Technical Context
The OPA2376AQDRQ1 implements TI's e-trim™ technology to achieve 5 μV typical input offset voltage and 0.32 μV/°C max drift over –40°C to +125°C. Its CMOS input stage enables 0.2 pA typical input bias current and rail-to-rail common-mode range extending 100 mV beyond supply rails.
This dual op amp features unity-gain stability, supports capacitive loads up to 250 pF in buffer configuration, and maintains 90 dB minimum CMRR and 120 dB open-loop gain at 25°C. Its 2 V/μs slew rate and 1.6 μs 0.1% settling time support fast-sampling SAR ADC driving in motor control feedback loops.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV772MA/NOPB | Higher 17 nV/√Hz noise, 250 μV max offset, 1.5 MHz GBW, 1.2 mA IQ | Lower accuracy and bandwidth; suitable only for non-critical signal conditioning | Select when cost sensitivity outweighs noise/accuracy requirements and AEC-Q100 is not mandated |
| TSV912IQ2T | 11 nV/√Hz noise, 1.5 mV max offset, 8 MHz GBW, 820 μA IQ, AEC-Q100 Grade 1 | Higher offset limits dc precision; wider bandwidth suits faster control loops | Prefer for higher-speed motor control where moderate dc accuracy suffices and layout allows tighter noise filtering |

FAQ
What is the maximum capacitive load the OPA2376AQDRQ1 can drive in unity-gain configuration?
The OPA2376AQDRQ1 can directly drive up to 250 pF of pure capacitive load in unity-gain buffer configuration while maintaining stability. For larger loads, a 10 Ω to 20 Ω series resistor at the output improves phase margin without degrading dc accuracy-verified in TI's Figure 7-1 and Section 7.3.3 of the SBOS549C datasheet. This capability is critical for driving ADC input capacitance in automotive data acquisition systems.
Does the OPA2376AQDRQ1 support rail-to-rail input common-mode voltage?
Yes, the OPA2376AQDRQ1 supports rail-to-rail input common-mode voltage with 100 mV beyond both supply rails (V– – 0.1 V to V+ + 0.1 V). Its offset voltage remains stable across this full range except above (V+) – 1 V, where it increases gradually-documented in Figure 6-9 and Section 7.3.4. This enables direct interfacing with sensors operating at ground or supply-referenced levels in single-supply automotive systems.
Is the OPA2376AQDRQ1 pin-compatible with other devices in the OPAx376-Q1 family?
No-OPA2376AQDRQ1 uses an 8-pin VSSOP (DGK) package with dedicated dual-channel pinout (Table 5-2), while OPA376-Q1 is offered in SC70-5, SOT-23-5, and SOIC-8 packages with different pin counts and assignments. The OPA4376-Q1 uses a 14-pin TSSOP. Pin compatibility exists only within same-channel-count variants sharing identical package types, such as OPA2376AQDRQ1 and non-Q1 OPA2376AIDR-but not across channel count or package families.
What functional safety documentation is available for the OPA2376AQDRQ1?
Texas Instruments provides functional safety documentation for OPA2376AQDRQ1 including FIT rate data, failure mode effect analysis (FMEA), and diagnostic coverage metrics-all accessible via TI's functional safety portal and referenced in the SBOS549C datasheet Features section. These resources support ISO 26262 ASIL-B system-level development but do not constitute certification; system-level validation remains the customer's responsibility.
How does the e-trim™ technology in the OPA2376AQDRQ1 improve long-term stability?
e-trim™ technology performs final-stage laser trimming of internal resistors during wafer probe or final test, compensating for process-induced mismatches and post-mold shifts. This yields 5 μV typical input offset voltage with ≤0.32 μV/°C drift over –40°C to +125°C-verified in Section 6.7 and Figure 6-16. Unlike traditional trim methods, e-trim™ minimizes aging-related drift, ensuring measurement consistency over 15+ year automotive service lifetimes without recalibration.
