Product details
Overview
5962-9564002Q2A from Texas Instruments is a dual rail-to-rail output operational amplifier in the TLC225x family, designed for high-impedance signal conditioning in low-power systems. It delivers 19 nV/√Hz input-referred noise at 1 kHz, 1 pA typical input bias current, and 35 µA per channel supply current. Its common-mode input range includes the negative rail and output swing extends to both supply rails, making it suitable for single-supply interfacing with precision ADCs in battery-powered sensor front-ends.
For engineers reviewing the 5962-9564002Q2A datasheet, 5962-9564002Q2A pinout, 5962-9564002Q2A application, or 5962-9564002Q2A equivalent, key selection criteria include its Q-temp automotive qualification (–40°C to 125°C), 850 µV max input offset voltage (TLC2252AQ grade), rail-to-rail output drive into 100 kΩ, and compatibility with ±2.2 V to ±8 V dual supplies or 4.4 V to 16 V single supplies.
Technical Context
The 5962-9564002Q2A implements Advanced LinCMOS™ process technology to achieve micropower operation without sacrificing input impedance or noise performance. Its input stage supports common-mode voltages down to the negative rail, and the output stage uses complementary push-pull circuitry enabling full rail-to-rail swing under load.
This device is fully characterized across –40°C to 125°C and qualified to MIL-PRF-38535 Class Q standards for high-reliability automotive applications. It features 10¹² Ω differential and common-mode input resistance, 70 dB minimum CMRR over temperature, and stable unity-gain operation with 63° phase margin driving 100 pF capacitive loads.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift vs. 0.5 µV/°C for 5962-9564002Q2A; higher quiescent current (17 µA per channel vs. 35 µA). | Superior DC accuracy for long-term unattended measurements; less suitable for ultra-low-power wake-up sensor nodes. | Select OPA2333AIDR when sub-µV drift dominates system error budget over battery life. |
| LMV722QDR | Higher GBW (10 MHz vs. 0.21 MHz); higher supply current (160 µA/channel); not MIL-qualified. | Better for AC-coupled active filters or higher-frequency sensor interfaces; lacks Q-grade screening and extended temperature validation. | Select LMV722QDR only for commercial-temperature, higher-speed applications where radiation tolerance and AEC-Q100 compliance are not required. |
Compared with OPA2333AIDR and LMV722QDR, the 5962-9564002Q2A uniquely balances ultra-low power (35 µA), Q-grade reliability, and rail-to-rail output in a hermetic ceramic package-making it irreplaceable for mission-critical, low-duty-cycle sensing in harsh environments.

FAQ
What is the maximum operating supply voltage for the 5962-9564002Q2A?
The 5962-9564002Q2A supports a maximum supply voltage of ±8 V in dual-supply mode or 16 V in single-supply mode, as specified in its absolute maximum ratings. Operation beyond these limits risks permanent damage. The recommended operating range is ±2.2 V to ±8 V (dual) or 4.4 V to 16 V (single), with full electrical characterization validated across this span for the 5962-9564002Q2A.
Does the 5962-9564002Q2A support true rail-to-rail input capability?
No, the 5962-9564002Q2A does not provide rail-to-rail input common-mode range. Its input common-mode voltage range extends to the negative rail (VDD–/GND) but stops 1.5 V below the positive rail (VDD+) under all operating conditions. However, its output swing is truly rail-to-rail-reaching within 20 mV of both supply rails into 100 kΩ loads-making it ideal for maximizing dynamic range at the output stage of the 5962-9564002Q2A.
What packaging and screening level does the 5962-9564002Q2A use?
The 5962-9564002Q2A is supplied in an 8-pin ceramic dual-in-line package (JG) and is screened to MIL-PRF-38535 Class Q standards. This includes rigorous burn-in, temperature cycling, and parametric testing across –55°C to 125°C, with full traceability and lot-level documentation required for defense and space applications-distinct from commercial-grade TLC2252 variants.
How does the 5962-9564002Q2A differ from the standard TLC2252AQ?
The 5962-9564002Q2A is the QML-certified (MIL-PRF-38535) version of the TLC2252AQ, sharing identical electrical specifications-including 850 µV max input offset voltage, 35 µA/channel supply current, and rail-to-rail output-but subjected to additional military-grade screening, lot acceptance testing, and hermetic ceramic packaging. The "Q2A" suffix denotes QML-V qualification with enhanced reliability reporting for the 5962-9564002Q2A.
Can the 5962-9564002Q2A drive capacitive loads without instability?
Yes, the 5962-9564002Q2A is unity-gain stable with a 63° phase margin when driving up to 100 pF capacitive loads with a 50 kΩ series resistor, as verified in its datasheet operating characteristics. For direct capacitive loads exceeding 100 pF, a small isolation resistor (≥100 Ω) is recommended between the 5962-9564002Q2A output and the capacitor to maintain stability and prevent peaking or oscillation.
