Product details
Overview
5962-9751002QPA from Texas Instruments is a dual-channel, rail-to-rail output operational amplifier optimized for wide-input-voltage, low-power, high-impedance signal conditioning in military and aerospace applications. It delivers 950 µV max input offset voltage at 25°C, 18 nV/√Hz input voltage noise at 1 kHz, 125 µA per channel supply current at 5 V, and operates across –40°C to 125°C with ±2.5 V (5 V) supply capability. It is used in precision sensor front-ends and analog-to-digital converter (ADC) interfacing where phase inversion immunity and extended common-mode range are critical.
For engineers reviewing the 5962-9751002QPA datasheet, 5962-9751002QPA pinout, 5962-9751002QPA application, or 5962-9751002QPA equivalent, key selection criteria include its Q-level qualification per MIL-PRF-38535, guaranteed rail-to-rail output swing into 600-Ω loads, no phase inversion over rail-to-rail common-mode input, and compatibility with 2.7–10 V single-supply operation - all validated for high-reliability embedded systems.
Technical Context
The 5962-9751002QPA implements an Advanced LinCMOS™ process architecture enabling ultra-low input bias current (1 pA typ) and high input impedance (>1 TΩ), making it suitable for piezoelectric transducer amplification and high-impedance source buffering. Its internal compensation ensures stable unity-gain operation with 62° phase margin at 100 kHz when driving 2 kΩ || 100 pF loads.
It features a fully differential input stage with extended common-mode input range (0 V to 4.5 V min on 5 V supply) and rail-to-rail output stage capable of sourcing/sinking ±3 mA while maintaining <1.25 V low-level and >4 V high-level output voltage under load - critical for direct interfacing with SAR and sigma-delta ADCs requiring full-scale analog input swing.

Pinout & Package
Ceramic flatpack (U) package with 8 leads, hermetically sealed, compliant with MIL-STD-883 testing requirements for high-reliability deployment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output A | Rail-to-rail output capable of swinging within 100 mV of either rail under 3 mA load. |
| 2 | Inverting Input A | Differential input node with 1000 GΩ common-mode resistance - minimizes loading on high-Z sources. |
| 3 | Non-inverting Input A | High-impedance input referenced to system ground or virtual ground; immune to phase reversal at supply rails. |
| 4 | Ground / VDD– | Power return path shared by both amplifiers; requires low-inductance connection to minimize crosstalk. |
| 5 | VDD+ | Positive supply input rated for 12 V absolute max; decoupling capacitor mandatory for stability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333MDRGTEP | Zero-drift architecture; 0.02 µV/°C offset drift vs. 2 µV/°C for 5962-9751002QPA; higher quiescent current (17 µA vs. 125 µA per channel). | Used in ultra-stable DC-coupled medical instrumentation; not qualified to MIL-PRF-38535. | Select when nanovolt-level drift dominates over radiation tolerance and extended temperature range. |
| LM158AH/883 | Bipolar input; 2 mV max VIO; 200 nA IIB; wider supply range (3–36 V); no rail-to-rail output. | Legacy military designs requiring proven field reliability but tolerating reduced dynamic range and higher input error. | Select when interoperability with existing bipolar-based schematics is required and rail-to-rail output is not essential. |
Compared with OPA2333MDRGTEP and LM158AH/883, the 5962-9751002QPA uniquely balances QML-Q qualification, rail-to-rail output, sub-microvolt offset, and picoampere bias current - making it irreplaceable in new high-reliability analog signal chains where all four attributes are simultaneously mandated.

FAQ
What is the absolute maximum supply voltage rating for the 5962-9751002QPA?
The 5962-9751002QPA has an absolute maximum supply voltage rating of 12 V across VDD+ and VDD– terminals. Operation beyond this limit risks permanent damage. Recommended operating range is 2.7 V to 10 V. This rating is verified per MIL-STD-883 Method 3015 and applies to both single-supply (VDD+, GND) and split-supply (±VDD) configurations. The 5962-9751002QPA must be operated within these limits to maintain QML-Q qualification compliance.
Does the 5962-9751002QPA support true rail-to-rail input operation?
No, the 5962-9751002QPA provides rail-to-rail *output* swing but not rail-to-rail *input*. Its common-mode input voltage range extends from VDD– to (VDD+ – 1.3 V) - for example, 0 V to 3.7 V on a 5 V supply. This wide-input-voltage capability avoids phase inversion near the rails but does not include the negative rail in the input range. The 5962-9751002QPA is explicitly characterized for this behavior in its SLOS168F datasheet Figure 4 and Table 1.
What is the guaranteed output current capability of the 5962-9751002QPA at 125°C?
The 5962-9751002QPA guarantees ±3 mA output current into resistive loads at full operating temperature (–40°C to +125°C), as confirmed in the "Electrical Characteristics" tables for Q-level parts (page 7, SLOS168F). This is measured at VOH ≥4.0 V and VOL ≤1.25 V with VDD = 5 V. Output drive remains stable across temperature due to Advanced LinCMOS™ process design, and the 5962-9751002QPA maintains 600-Ω load capability without thermal shutdown under continuous operation.
Is the 5962-9751002QPA compatible with standard SOIC-8 PCB footprints?
No, the 5962-9751002QPA uses a ceramic flatpack (U) package with 0.300-inch body width and 0.050-inch lead pitch - incompatible with SOIC-8 land patterns. Its pin spacing, lead form (flat gull-wing), and hermetic sealing require dedicated layout per MIL-PRF-38535 mechanical drawings. Substituting into SOIC-8 layouts would cause solder joint reliability failure and violate QML-Q assembly requirements. The 5962-9751002QPA must be mounted using its specified U-package footprint.
How does the 5962-9751002QPA handle input overvoltage conditions beyond its common-mode range?
The 5962-9751002QPA includes internal ESD protection diodes that clamp input voltages exceeding VDD– by more than 0.3 V or VDD+ by more than 0.3 V, limiting current to ±5 mA per input (per Absolute Maximum Ratings table, page 4). Exceeding these clamping thresholds risks latch-up or parametric shift. For robust overvoltage protection, external series resistors (≥10 kΩ) and Schottky clamps to rails are recommended. This behavior is documented in Note 2 of the 5962-9751002QPA datasheet.
