Product details
Overview
5962-9751401Q2A from Texas Instruments is a dual rail-to-rail output, micropower operational amplifier designed for high-reliability automotive and military applications. It features 50 µA per channel supply current, 950 µV max input offset voltage (TA = 25°C), rail-to-rail output swing (0 V to VDD), and extended common-mode input range (0 V to 4.5 V min at 5-V supply). It is used in precision sensor signal conditioning within harsh-environment vehicle control modules.
For engineers reviewing the 5962-9751401Q2A datasheet, 5962-9751401Q2A pinout, 5962-9751401Q2A application, or 5962-9751401Q2A equivalent, key selection criteria include its Q-temp automotive qualification (–40°C to 125°C), low 1 pA typical input bias current, 18 nV/√Hz input voltage noise at 1 kHz, 600-Ω output drive capability, and absence of phase inversion near supply rails.
Technical Context
The 5962-9751401Q2A implements an Advanced LinCMOS™ process architecture enabling rail-to-rail output operation without phase inversion when common-mode inputs approach VDD or VDD–/GND. Its input stage supports wide common-mode range (0 V to VDD – 0.8 V) and exhibits ultra-low input bias current (1 pA typ) due to CMOS input transistors.
It delivers micropower performance (100–150 µA per channel at 25°C) while maintaining usable gain-bandwidth (46–52 kHz at VDD = 3–5 V) and 600-Ω load drive - a deliberate trade-off optimized for battery-powered, low-voltage analog front-ends where quiescent current and output headroom are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports single-supply operation from Li-ion (3.3 V) up to industrial 5 V or 9 V rails. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - enables accurate DC-coupled amplification in precision sensor interfaces without trimming. |
| Supply Current per Channel | 100–150 µA at 25°C - allows multi-channel signal conditioning in power-constrained automotive ECUs. |
| Output Drive Capability | ±50 mA short-circuit current; drives 600-Ω loads - sufficient for direct interfacing with ADC reference buffers or low-Z transducer drivers. |
| Input Bias Current (typ) | 1 pA - preserves signal integrity from high-impedance sources like piezoelectric sensors or pH electrodes. |
| Input Voltage Noise | 18 nV/√Hz at f = 1 kHz - suitable for low-frequency (<10 kHz) sensor signal amplification with minimal added noise. |
| Common-Mode Input Range | 0 V to VDD – 0.8 V - accepts ground-referenced or rail-referenced inputs without external level-shifting. |
Pinout & Package
Ceramic Flat Pack (U) package, 20-pin, hermetically sealed, qualified per MIL-PRF-38535 Class Q for high-reliability applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 4, 6, 7, 9, 11, 13, 14, 16, 17, 19 | No internal connection (NC) | Unused pins; must be left floating or tied to GND per layout guidelines - no electrical function. |
| 2 | Amplifier 2 Output | Delivers rail-to-rail output voltage; capable of sourcing/sinking ±50 mA into 600-Ω loads. |
| 5 | Amplifier 2 Inverting Input | High-impedance (10¹² Ω) CMOS input; sensitive to PCB leakage and EMI coupling. |
| 8 | Amplifier 2 Non-Inverting Input | Same impedance and noise characteristics as Pin 5; differential pair input node. |
| 10 | Amplifier 1 Output | Independent rail-to-rail output; electrically isolated from Pin 2 except via shared supply rails. |
| 12 | Amplifier 1 Inverting Input | Matches Pin 5 in specs; supports unity-gain stable configurations with >62° phase margin. |
| 15 | Amplifier 1 Non-Inverting Input | Matches Pin 8; enables dual-channel instrumentation or parallel signal paths. |
| 18 | VDD+ | Positive supply terminal; requires local 0.1-µF ceramic decoupling to minimize PSRR degradation. |
| 20 | VDD–/GND | Ground reference for single-supply operation; serves as return path for both amplifiers and output loads. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Swings within 25 mV of VDD and GND at 500 µA load - maximizes dynamic range for 12-bit+ ADC interfacing. |
| No phase inversion | Operates linearly with common-mode inputs driven to either supply rail - eliminates output glitches in over-range conditions. |
| Extended common-mode input range | 0 V to 4.5 V (min) at 5-V supply - accepts ground-sensed signals without level-shifting circuitry. |
| Low input bias current (1 pA typ) | Minimizes voltage error across high-impedance source impedances (>1 MΩ) - critical for electrochemical sensors. |
| Q-temp automotive qualification | Qualified per AEC-Q100 and MIL-PRF-38535 Class Q (–40°C to 125°C) - assured operation in engine bay and transmission control units. |
Applications
| Automotive Engine Control Unit (ECU) Sensor Interface | Industrial Battery-Powered Data Logger |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2422AQDR | Same die, SOIC-8 package (Pb-free, RoHS-compliant); wider temp range (–40°C to 125°C) but non-hermetic plastic body. | Lacks MIL-PRF-38535 qualification and hermetic sealing - unsuitable for aerospace or mission-critical automotive safety systems. | Select only for cost-sensitive, non-safety-critical industrial designs where plastic packaging and commercial traceability suffice. |
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C max offset drift vs. 2 µV/°C for 5962-9751401Q2A; higher 17 µA per channel IDD. | Better DC precision for ultra-low-drift applications (e.g., precision weigh scales), but higher power and no Q-temp/MIL qualification. | Choose when sub-µV drift dominates over power and qualification requirements; avoid where military/aerospace certification is mandatory. |
Compared with TLV2422AQDR and OPA2333AIDR, the 5962-9751401Q2A uniquely combines MIL-PRF-38535 Class Q qualification, hermetic ceramic packaging, and micropower rail-to-rail operation - making it irreplaceable in safety-critical, high-temperature, or long-lifecycle embedded systems where component pedigree and environmental resilience are non-negotiable.

FAQ
What is the maximum operating temperature range for the 5962-9751401Q2A?
The 5962-9751401Q2A is rated for operation from –40°C to +125°C ambient temperature, meeting Q-temp automotive qualification requirements. This range is validated per MIL-PRF-38535 Class Q test flow and includes full electrical characterization across the entire span, not just derated parameters at extremes.
Does the 5962-9751401Q2A support true rail-to-rail input operation?
No - the 5962-9751401Q2A provides rail-to-rail *output* swing but has an extended common-mode input range (0 V to VDD – 0.8 V), not rail-to-rail input. Its input stage does not operate with inputs at VDD or GND, unlike dedicated RRI op-amps. However, it avoids phase inversion when inputs approach the rails.
Is the 5962-9751401Q2A pin-compatible with standard SOIC-8 dual op-amps?
No - the 5962-9751401Q2A uses a 20-pin Ceramic Flat Pack (U) package with numerous NC pins and non-standard pin assignments. It is not pin-compatible with SOIC-8, MSOP-8, or TSSOP-8 dual op-amps. Layout redesign is required for substitution.
What is the typical input bias current specification for the 5962-9751401Q2A?
The 5962-9751401Q2A exhibits a typical input bias current of 1 pA at 25°C, with a maximum of 150 pA across its full operating temperature range (–40°C to 125°C). This ultra-low value stems from its CMOS input stage and enables use with high-impedance sensors without significant offset error.
Can the 5962-9751401Q2A drive a 10-kΩ load with rail-to-rail output swing?
Yes - the 5962-9751401Q2A maintains rail-to-rail output swing (within 25 mV of rails) when driving ≥10-kΩ loads. Its 600-Ω drive capability ensures robust performance even into lower-impedance loads, but for 10-kΩ, output swing remains fully specified and stable across temperature and supply voltage.
