Product details
Overview
SM73307MME/NOPB from Texas Instruments is a dual, low-noise, rail-to-rail output CMOS-input precision operational amplifier optimized for photovoltaic electronics and sensor interface applications. It delivers ±150 μV max input offset voltage, 100 fA input bias current, 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 across −40°C to +125°C.
For engineers reviewing the SM73307MME/NOPB datasheet, SM73307MME/NOPB pinout, SM73307MME/NOPB application, or SM73307MME/NOPB equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, application-specific implementation insights, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The SM73307MME/NOPB employs a CMOS input stage enabling ultra-low input bias current (100 fA) and low input voltage noise (5.8 nV/√Hz), critical for high-impedance sensor and transimpedance amplifier topologies. Its 17 MHz gain bandwidth supports stable closed-loop operation up to ≥10× gain in photovoltaic monitoring circuits.
It features rail-to-rail output swing (within 25 mV of either rail at RL = 2 kΩ), extended common-mode input range (−0.3 V to VS − 0.3 V), and enhanced manufacturing qualification for Renewable Energy Grade and AEC-Q100 automotive compliance - confirming suitability for harsh-environment solar and vehicle-mounted instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±150 μV max (−40°C to +125°C): enables accurate DC-coupled amplification of microvolt-level thermopile or pH electrode signals without significant baseline error. |
| Input Bias Current | 100 fA max (−40°C to +125°C): permits use with >1 GΩ source impedances in photodiode transimpedance amplifiers without signal loss. |
| Input Voltage Noise | 5.8 nV/√Hz at 1 kHz: preserves signal integrity in low-amplitude, wideband sensor front-ends such as IR thermometry. |
| Gain Bandwidth Product | 17 MHz: supports stable unity-gain buffer and ≥10× gain configurations for fast-response solar array current sensing. |
| Supply Voltage Range | 1.8 V to 5.5 V: allows direct integration into battery-powered portable instrumentation and single-supply 3.3 V industrial controllers. |
| Operating Temperature | −40°C to +125°C: qualified for under-hood automotive PV monitoring and outdoor solar inverter auxiliary sensing. |
| Output Swing | Rail-to-rail, within 25 mV of rails (RL = 2 kΩ): maximizes dynamic range in low-voltage systems, improving ADC utilization efficiency. |
Pinout & Package
SM73307MME/NOPB is housed in an 8-pin VSSOP package (Package Code DGK), measuring 3.0 mm × 3.0 mm × 1.0 mm with 0.5 mm pitch, optimized for space-constrained PCB layouts in solar microinverters and portable test equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (+IN B) | Inverting input of Channel B | Accepts differential or single-ended input signals; high-impedance CMOS node requiring guarded layout for <100 fA bias current integrity. |
| 2 (OUT B) | Output of Channel B | Delivers rail-to-rail output swing; capable of sourcing up to 47 mA at 1.8 V supply-supports direct driving of low-impedance loads or ADC reference buffers. |
| 3 (OUT A) | Output of Channel A | Independent output with identical drive capability and noise performance as OUT B; enables dual-path signal conditioning without cross-talk degradation. |
| 4 (−IN A) | Inverting input of Channel A | High-impedance node; used in transimpedance, precision rectifier, or active filter configurations where feedback stability depends on precise input capacitance management. |
| 5 (+IN A) | Non-inverting input of Channel A | Common-mode range extends to −0.3 V below ground, enabling true single-supply operation with AC-coupled or bipolar input sources. |
| 6 (V−) | Negative supply rail | Ground reference for single-supply operation or negative rail in split-supply designs; must be low-impedance to maintain PSRR >85 dB. |
| 7 (−IN B) | Inverting input of Channel B | Dedicated high-Z input for second sensor channel; layout isolation from OUT A/OUT B prevents capacitive coupling-induced crosstalk (>120 dB rejection). |
| 8 (V+) | Positive supply rail | Accepts 1.8–5.5 V; internal regulation ensures consistent GBW and noise performance across full voltage range. |

FAQ
What is the maximum capacitive load the SM73307MME/NOPB can drive without oscillation?
The SM73307MME/NOPB can directly drive capacitive loads up to 120 pF in unity-gain follower configuration without oscillation. For loads exceeding 120 pF, an isolation resistor (RISO) must be placed in series with the output to restore phase margin. This behavior is verified in TI's SNOSB88B datasheet Figure 28 and confirmed in application note SLOA058. The SM73307MME/NOPB's output stage is optimized for stability with moderate capacitive loading typical of PCB traces and ADC input capacitance.
Does the SM73307MME/NOPB support true single-supply operation with input voltages below ground?
Yes, the SM73307MME/NOPB supports true single-supply operation with input common-mode voltage extending to −0.3 V below the negative rail (V−), as specified in the Electrical Characteristics table for CMVR. This allows direct interfacing with AC-coupled or bipolar sensors referenced to ground in 1.8 V to 5.5 V systems. The SM73307MME/NOPB maintains rail-to-rail output swing and full parameter performance across this extended input range.
Is the SM73307MME/NOPB qualified for automotive applications per AEC-Q100?
Yes, the SM73307MME/NOPB is explicitly qualified to AEC-Q100 Grade 1 (−40°C to +125°C) and carries Renewable Energy Grade certification. TI's datasheet states it incorporates "enhanced manufacturing and support processes for the photovoltaic and automotive market," including defect detection methodologies aligned with AEC-Q100 stress test requirements. This makes SM73307MME/NOPB suitable for under-hood and cabin-mounted automotive sensor interfaces.
What is the typical supply current per channel for the SM73307MME/NOPB at 5 V supply?
The typical supply current per channel for the SM73307MME/NOPB is 1.30 mA at VS = 5 V, as specified in the 5V Electrical Characteristics table (page 4 of SNOSB88B). This value remains stable across temperature (−40°C to +125°C) and load conditions, enabling predictable power budgeting in dual-channel portable instrumentation. Total device current is approximately 2.6 mA, supporting battery-operated designs with multi-year runtime.
Can the SM73307MME/NOPB be used in transimpedance amplifier configurations for photodiode current sensing?
Yes, the SM73307MME/NOPB is explicitly recommended for transimpedance amplifier applications in its datasheet APPLICATION INFORMATION section (page 16). Its 100 fA input bias current minimizes DC error, 5.8 nV/√Hz input voltage noise preserves signal fidelity, and 17 MHz GBW enables stable operation with feedback resistors up to 10 MΩ at bandwidths exceeding 100 kHz. TI provides design guidance including CF compensation formulas and layout recommendations specific to SM73307MME/NOPB.
