Product details
Overview
5962-9564003Q2A from Texas Instruments is a dual rail-to-rail output operational amplifier in the TLC225x family, designed for high-impedance signal conditioning in battery-powered systems. It delivers 35 µA per channel supply current, 19 nV/√Hz input voltage noise at 1 kHz, and 850 µV maximum input offset voltage at 25°C, operating across –40°C to 125°C with ±2.2 V to ±8 V supply range.
For engineers reviewing the 5962-9564003Q2A datasheet, 5962-9564003Q2A pinout, 5962-9564003Q2A application, or 5962-9564003Q2A equivalent, key selection criteria include micropower operation, rail-to-rail output swing, low input bias current (1 pA typ), wide common-mode input range including negative rail, and qualification for high-reliability automotive environments.
Technical Context
The 5962-9564003Q2A implements Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining ultra-low input bias current (1 pA typ) and low noise (19 nV/√Hz). Its input stage supports common-mode voltage down to the negative rail, enabling single-supply sensor interfacing without level-shifting circuitry.
It is fully specified for both single-supply (e.g., +5 V) and split-supply (e.g., ±5 V) operation, with guaranteed performance over –40°C to 125°C. The device features internal ESD protection, macromodel support, and is qualified to MIL-PRF-38535 Class Q standards for high-reliability applications.

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 5962-9564003Q2A; higher supply current (17 µA/ch vs. 35 µA/ch). | Superior DC accuracy for long-term drift-sensitive applications; less suitable for ultra-low-power wake-up circuits. | Select OPA2333AIDR when microvolt-level stability over temperature/time outweighs micropower priority. |
| LMV722QDR | Higher bandwidth (10 MHz vs. 0.21 MHz); higher supply current (120 µA/ch); not MIL-qualified; commercial temp range only (–40°C to 125°C). | Better suited for AC-coupled signal paths requiring faster settling; lacks radiation-hardened packaging and Q-grade screening. | Select LMV722QDR for cost-sensitive automotive infotainment or body electronics where military reliability is not mandated. |
Compared with OPA2333AIDR and LMV722QDR, the 5962-9564003Q2A uniquely balances ultra-low power (35 µA/ch), rail-to-rail output, 1 pA input bias, and MIL-PRF-38535 Class Q qualification-making it irreplaceable in high-reliability, battery-limited embedded systems where all four attributes are simultaneously required.

FAQ
What is the maximum supply voltage rating for the 5962-9564003Q2A?
The 5962-9564003Q2A has an absolute maximum supply voltage rating of ±8 V across VDD+ and VDD– terminals. Operation beyond this limit risks permanent damage. Recommended operating range is ±2.2 V to ±8 V, with full electrical specifications guaranteed across that span. This rating applies to both split-supply and single-supply configurations (e.g., 0 V to 16 V).
Does the 5962-9564003Q2A support true rail-to-rail input capability?
No-the 5962-9564003Q2A provides rail-to-rail *output* swing but its common-mode input voltage range extends only to VDD– and up to VDD+ –1.5 V. At ±5 V supply, this yields a usable input range of –5 V to +3.5 V. This design enables robust operation with ground-referenced sensors while maintaining low input bias current via the Advanced LinCMOS™ process.
How does the 5962-9564003Q2A differ from the commercial-grade TLC2252CD?
The 5962-9564003Q2A is the MIL-PRF-38535 Class Q qualified version of the TLC2252A, featuring hermetic ceramic DIP packaging, extended temperature validation (–40°C to 125°C), rigorous screening for burn-in and parametric limits, and full compliance with military quality assurance requirements. The TLC2252CD is a commercial plastic DIP variant rated only for 0°C to 70°C and lacks radiation hardness or lot traceability.
Can the 5962-9564003Q2A drive capacitive loads directly?
The 5962-9564003Q2A is stable with capacitive loads up to 100 pF when configured with unity-gain feedback and a 50 kΩ load resistor, as verified by phase margin (63°) and gain margin (15 dB) measurements. For loads exceeding 100 pF, external isolation resistance (e.g., 10 Ω–50 Ω in series with the output) is recommended to maintain stability and prevent peaking or oscillation in precision measurement paths.
Is a SPICE macromodel available for the 5962-9564003Q2A?
Yes-a validated SPICE macromodel for the TLC2252A (the base commercial-grade device) is included in the official SLOS176D datasheet and available for download from Texas Instruments' website. While the 5962-9564003Q2A shares identical electrical behavior, users should apply derating factors for temperature extremes and validate timing margins under worst-case process corners when simulating for Class Q applications.
