Product details
Overview
SM73308MG/NOPB from Texas Instruments is a single-channel, rail-to-rail output, low-noise precision operational amplifier designed for high-accuracy signal conditioning in harsh environments. It delivers 3.5 MHz gain-bandwidth product, 850 µV max input offset voltage, 7.5 nV/√Hz voltage noise at 10 kHz, and operates from 2.7 V to 5.5 V supply across −40°C to 125°C - enabling use in automotive sensor front-ends and industrial current sensing.
For engineers reviewing the SM73308MG/NOPB datasheet, SM73308MG/NOPB pinout, SM73308MG/NOPB application, or SM73308MG/NOPB equivalent, key selection criteria include its SC70-5 package footprint, guaranteed 2.7 V/5 V performance, ultra-low input bias current (≤250 pA), extended temperature operation, and rail-to-rail output swing within 50 mV of rails into 2 kΩ loads.
Technical Context
The SM73308MG/NOPB employs a precision bipolar-input architecture optimized for low offset drift (−0.35 µV/°C typical) and low 1/f noise, with input common-mode range extending to V− and up to V+ − 0.9 V. Its open-loop gain exceeds 100 dB into 2 kΩ, supporting stable closed-loop configurations down to unity gain.
It features internal compensation for unity-gain stability with capacitive loads up to 500 pF, maintains phase margin ≥79° at 5 V supply, and achieves 1.4 V/µs slew rate - balancing speed, noise, and DC precision without requiring external trimming components.
Key Specifications

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; 0.02 µV/°C TCVOS vs. SM73308MG/NOPB's −0.35 µV/°C; higher quiescent current (17 µA vs. 0.9 mA) | Better long-term DC stability in ultra-low-drift systems; less suitable for low-power battery operation | Select OPA333AIDBVR when offset drift dominates error budget; choose SM73308MG/NOPB for lower power + wider supply range |
| LMV721IDBVR | Higher input bias current (100 nA vs. 250 pA); lower GBW (1.5 MHz vs. 3.5 MHz); same SC70-5 package | Lower cost for non-critical industrial sensing; insufficient for high-speed data acquisition or low-impedance sensor interfaces | Choose LMV721IDBVR only where VOS <1.5 mV and noise >20 nV/√Hz are acceptable; SM73308MG/NOPB preferred for renewable energy grade specs |
Compared with OPA333AIDBVR and LMV721IDBVR, SM73308MG/NOPB uniquely balances ultra-low noise (7.5 nV/√Hz), extended temperature operation (−40°C to 125°C), and low supply current (550 µA) in the SC70-5 footprint - making it optimal for automotive and industrial precision analog front-ends where power, noise, and reliability are co-constrained.

FAQ
What is the maximum input offset voltage specification for SM73308MG/NOPB over temperature?
The SM73308MG/NOPB has a maximum input offset voltage of 1.0 mV across the full −40°C to 125°C operating range, with tighter limits of 0.85 mV at room temperature (25°C). This guaranteed limit is specified in the Electrical Characteristics tables for both 2.7 V and 5.0 V supply conditions, ensuring predictable DC error in precision sensor interfaces without trimming.
Does SM73308MG/NOPB support rail-to-rail input common-mode voltage?
No, SM73308MG/NOPB does not support rail-to-rail input. Its input common-mode voltage range is specified as 0 V to V+ − 0.9 V - meaning it accepts signals down to ground but cannot accommodate inputs within 0.9 V of the positive rail. This limitation is clearly defined in the Electrical Characteristics table under "VCM" for both 2.7 V and 5.0 V supplies.
What is the recommended minimum load resistance for SM73308MG/NOPB to maintain rail-to-rail output swing?
To achieve rail-to-rail output swing within 50 mV of the supply rails, SM73308MG/NOPB requires a minimum load resistance of 2 kΩ. With a 600 Ω load, output swing degrades to within 100 mV of the rails. These values are explicitly tested and guaranteed in the datasheet's "VO" parameter table under both 2.7 V and 5.0 V supply conditions.
Is SM73308MG/NOPB qualified for automotive applications?
Yes, SM73308MG/NOPB is explicitly designated as "Renewable Energy Grade" and qualified for operation from −40°C to 125°C with guaranteed specifications at both extremes. While not AEC-Q100 certified by default, its extended temperature performance, robust ESD tolerance (2000 V HBM), and automotive-focused application notes confirm suitability for under-hood and cabin sensor front-ends where TI's extended reliability screening applies.
What package type and dimensions does SM73308MG/NOPB use?
SM73308MG/NOPB uses the SC70-5 package (TI Package Number DCK), measuring 2.0 mm × 2.1 mm × 0.9 mm with 0.65 mm lead pitch. This ultra-compact outline is documented in the "Mechanical Data" section of the SNOSB90B datasheet and is compatible with standard SMT reflow profiles including infrared and wave soldering up to 260°C for 10 seconds.
