Product details
Overview
SM73308MGX/NOPB from Texas Instruments is a single-channel, low-noise, rail-to-rail output operational amplifier optimized for precision signal conditioning in harsh environments. It delivers 3.5 MHz gain-bandwidth, 12.5 nV/√Hz input voltage noise at 100 Hz, ≤850 µV input offset voltage (max), and operates from 2.7 V to 5.5 V across −40°C to 125°C - enabling use in automotive sensor front-ends and high-accuracy current sensing.
For engineers reviewing the SM73308MGX/NOPB datasheet, SM73308MGX/NOPB pinout, SM73308MGX/NOPB application, or SM73308MGX/NOPB equivalent, key selection criteria include its guaranteed 2.7 V/5 V performance, SC70-5 package footprint, ultra-low input bias current (≤250 pA), extended temperature operation, and rail-to-rail output swing within 50 mV of rails into 2 kΩ.
Technical Context
The SM73308MGX/NOPB employs a precision bipolar-input architecture with integrated ESD protection and silicon-dust process enhancements for stability over temperature. Its input common-mode range extends to V− and up to V+ − 0.9 V, supporting ground-referenced transducer interfaces.
It features unity-gain stable compensation, 100 dB open-loop gain (RL = 2 kΩ), and phase margin of 79° at 5 V supply - enabling robust performance in active filters, instrumentation amplifiers, and closed-loop current-sense configurations without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 5.5 V - supports single-cell Li-ion and dual-cell alkaline systems without level-shifting. |
| Gain-Bandwidth Product | 3.5 MHz - enables stable closed-loop gain ≥10 at 350 kHz for anti-aliasing and sensor signal bandwidths. |
| Input Offset Voltage | ≤850 µV (max) - ensures ≤0.085% error in 1 V full-scale precision current sensing applications. |
| Voltage Noise Density | 7.5 nV/√Hz @ 10 kHz - minimizes noise contribution in 10–100 kHz instrumentation amplifier stages. |
| Rail-to-Rail Output | Swings to within 50 mV of rails @ 2 kΩ - preserves dynamic range in low-voltage data acquisition systems. |
| Input Bias Current | ≤250 pA @ 25°C - prevents significant error in high-impedance pH or thermopile sensor interfaces. |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive and industrial motor control environments. |
Pinout & Package
SM73308MGX/NOPB is housed in a 5-pin SC70 package (Package Number DCK), measuring 2.0 mm × 2.1 mm × 0.9 mm with 0.65 mm pitch. The package is moisture-sensitive level 1 (MSL-1) and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 (VOUT) | Amplifier Output | Delivers rail-to-rail voltage; capable of sourcing/sinking ≥35 mA short-circuit current (limited duty). |
| 3 (+IN) | Non-Inverting Input | High-impedance node (≥10¹³ Ω); connects to reference or sensor high-side in differential configurations. |
| 4 (GND) | Ground Reference | System return path; must be low-impedance and separated from power ground in mixed-signal layouts. |
| 5 (−IN) | Inverting Input | Feedback node in standard op-amp configurations; sensitive to PCB leakage and parasitic capacitance. |

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 max TCVOS vs. SM73308MGX/NOPB's 0.35 µV/°C; higher quiescent current (17 µA vs. 0.9 mA). | Better for DC-critical applications like precision DAC buffers; less suitable for wideband active filters due to lower GBW (350 kHz). | Select OPA333AIDBVR only when sub-µV drift dominates system error budget and bandwidth <100 kHz suffices. |
| TLV2782CDR | CMOS input; 1 pA IB vs. 250 pA; lower noise floor (11 nV/√Hz) but no guaranteed 2.7 V specs; narrower temp range (−40°C to 105°C). | Preferred for ultra-high-Z photodiode amps; not recommended for automotive under-hood use or 125°C industrial control. | Choose TLV2782CDR for battery-powered portable instruments where input impedance >1 TΩ is mandatory and ambient temp stays <105°C. |
Compared with OPA333AIDBVR and TLV2782CDR, SM73308MGX/NOPB uniquely balances low noise, guaranteed low-voltage operation, extended temperature range, and rail-to-rail output - making it optimal for automotive and industrial precision analog signal chains where all four attributes are simultaneously required.

FAQ
What is the maximum input offset voltage specification for SM73308MGX/NOPB across temperature?
The SM73308MGX/NOPB has a maximum input offset voltage of 850 µV at room temperature (25°C), and this limit is ensured across the full operating range of −40°C to 125°C per the datasheet's "Maximum VOS 850 µV (Limit)" specification. This value applies under standard test conditions with V+ = 2.7 V or 5.0 V and RL > 1 MΩ.
Does SM73308MGX/NOPB support rail-to-rail input common-mode voltage?
No, SM73308MGX/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 handle inputs within 0.9 V of the positive rail. This is confirmed in both 2.7 V and 5.0 V DC Electrical Characteristics tables.
What is the thermal resistance (θJA) of SM73308MGX/NOPB in the SC70-5 package?
The SM73308MGX/NOPB in the SC70-5 (DCK) package has a junction-to-ambient thermal resistance (θJA) of 440 °C/W, as specified in the Operating Ratings section. This value assumes standard JEDEC 2-layer board conditions and directly impacts maximum allowable power dissipation at elevated ambient temperatures.
Can SM73308MGX/NOPB drive capacitive loads without instability?
Yes, SM73308MGX/NOPB is stable with capacitive loads up to at least 500 pF when driving a 2 kΩ load, as shown in Figure 38 and Figure 39 of the datasheet. For heavier capacitive loads (>500 pF), isolation resistors or feedback capacitor compensation may be required to maintain 25% overshoot limits in pulse response.
Is SM73308MGX/NOPB pin-compatible with other SC70-5 op-amps like OPA333 or TLV2782?
No, SM73308MGX/NOPB is not pin-compatible with OPA333AIDBVR or TLV2782CDR. While all three use the SC70-5 package, their pinouts differ: SM73308MGX/NOPB assigns Pin 1 to V+, Pin 2 to VOUT, Pin 3 to +IN, Pin 4 to GND, and Pin 5 to −IN - whereas OPA333 and TLV2782 place VOUT on Pin 1 and V+ on Pin 5. PCB layout must be verified per each device's connection diagram.
