Product details
Overview
5962-9751402QPA from Texas Instruments is a Q-Temp automotive-grade dual rail-to-rail output operational amplifier optimized for low-voltage, micropower operation. It delivers 50 µA per channel supply current, 950 µV max input offset voltage (at TA = 25°C), 0 V to 4.5 V common-mode input range with 5-V supply, and 600-Ω output drive capability-enabling precision signal conditioning in battery-powered automotive sensor interfaces and analog front-ends.
For engineers reviewing the 5962-9751402QPA datasheet, 5962-9751402QPA pinout, 5962-9751402QPA application, or 5962-9751402QPA equivalent, key selection criteria include its extended common-mode input range, absence of phase inversion at rail extremes, micropower consumption, rail-to-rail output swing, and qualification to automotive temperature and reliability standards (–40°C to 125°C).
Technical Context
The 5962-9751402QPA employs Advanced LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typ) and high input impedance (10¹² Ω), making it suitable for high-impedance source interfacing such as piezoelectric transducers and remote sensors. Its architecture eliminates phase inversion when common-mode voltage reaches either supply rail-a critical advantage over standard CMOS op-amps in single-supply systems.
It is fully characterized at 3-V and 5-V supplies, supports rail-to-rail output swing (e.g., 4.97 V VOH at IOH = –100 µA, VDD = 5 V), and maintains stable operation with 100 pF capacitive loads. The device exhibits 18 nV/√Hz input voltage noise at 1 kHz and 46–52 kHz gain-bandwidth product depending on supply voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - Enables operation from single Li-ion cell (3.0 V) up to industrial 9-V rails without level-shifting. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - Supports precision DC-coupled amplification in automotive sensor signal chains requiring <1 mV error budget. |
| Supply Current per Channel | 100–150 µA typ at 25°C - Enables multi-channel monitoring in always-on vehicle subsystems with sub-300 µA total quiescent draw. |
| Common-Mode Input Range | 0 V to 4.5 V (min) with 5-V supply - Allows direct interface to 0–5 V sensor outputs without external biasing resistors. |
| Output Drive Capability | ±50 mA short-circuit current; drives 600-Ω loads - Sufficient for telecom line drivers and ADC reference buffer applications without external gain stages. |
| Input Bias Current | 1 pA typ - Preserves signal integrity from high-impedance sources like pH electrodes or photodiode transimpedance nodes. |
| Operating Temperature | –40°C to +125°C - Qualified per automotive Q-Temp requirements for under-hood and ADAS module deployment. |
Pinout & Package
Ceramic flat-pack (U) 20-pin package with hermetic sealing and gold-plated leads for high-reliability automotive use. Pin 1 marked via corner notch; pins 1–10 on top row left-to-right, pins 11–20 on bottom row right-to-left.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7, 9, 11, 13, 15, 17, 19 | No internal connection (NC) | Unused pins; must be left floating or grounded per layout guidelines to avoid parasitic coupling. |
| 2 | Amplifier 2 Output | Rail-to-rail output capable of sourcing/sinking ±50 mA; connects directly to ADC input or filter network. |
| 4 | Amplifier 2 Inverting Input | High-impedance node (10¹² Ω); sensitive to PCB leakage-requires guard ring in high-precision layouts. |
| 6 | Amplifier 2 Non-Inverting Input | Same high-Z characteristics as IN–; used for unity-gain buffers or differential sensing configurations. |
| 8 | Amplifier 1 Output | Independent rail-to-rail output; enables dual-path signal processing (e.g., differential pair or active filter stages). |
| 10 | Amplifier 1 Inverting Input | Matches pin 4 electrically; supports matched feedback networks across both channels. |
| 12 | Amplifier 1 Non-Inverting Input | Matches pin 6; allows identical configuration for both amplifiers in dual-sensor applications. |
| 14 | VDD+ | Positive supply rail; decoupling capacitor (0.1 µF ceramic) required within 5 mm for stability. |
| 16 | VDD– / GND | Ground reference or negative supply; shared return path mandates star grounding for dual-channel crosstalk control. |
| 18, 20 | NC | Electrically isolated; no internal bond wire-may be used for mechanical anchoring or thermal relief. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full dynamic range into ADCs: VOH = 4.97 V, VOL = 0.04 V (VDD = 5 V, IO = ±100 µA), minimizing headroom loss. |
| No phase inversion at supply rails | Enables robust single-supply operation with sensors whose output swings to ground or VDD-eliminates need for input clamping diodes. |
| Extended common-mode input range | 0 V to 4.5 V (min) with 5-V supply allows direct interface to 0–5 V industrial sensors without level-shifting circuitry. |
| 1 pA typical input bias current | Preserves accuracy in high-Z transducer interfaces (e.g., thermopiles, piezo elements) where leakage would otherwise dominate error. |
| Q-Temp automotive qualification | Fully tested and screened per MIL-PRF-38535 Class Q requirements, including temperature cycling, burn-in, and lot acceptance testing. |
| Low 18 nV/√Hz input voltage noise | Supports clean amplification of µV-level signals (e.g., strain gauges, ECG electrodes) without degrading SNR in bandwidth-limited systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2422AQD | Same die, plastic D-package (8-pin SOIC); not hermetically sealed; rated –40°C to 125°C but lacks MIL-PRF-38535 Q-level screening. | Suitable for cost-sensitive automotive modules where hermeticity and radiation tolerance are non-critical (e.g., infotainment). | Select TLV2422AQD only if board-level conformal coating and extended reliability testing can compensate for non-hermetic packaging. |
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C max drift vs. 2 µV/°C for 5962-9751402QPA; higher 17 µA/channel IDD; same 1.8–5.5 V supply range. | Better for DC-precision applications (e.g., weigh scales) but less optimal for wide-temp, low-IQ automotive use cases. | Choose OPA2333AIDR only when long-term offset stability dominates over quiescent current and temperature range requirements. |
Compared with TLV2422AQD and OPA2333AIDR, the 5962-9751402QPA uniquely combines Q-Temp qualification, hermetic U-package reliability, 50 µA/channel IQ, and rail-to-rail output-making it the sole option qualified for safety-critical under-hood analog signal paths without derating.

FAQ
What is the maximum operating temperature range for the 5962-9751402QPA?
The 5962-9751402QPA is rated for continuous operation from –40°C to +125°C and is fully qualified to Q-Temp automotive standards, including temperature cycling, burn-in, and lot acceptance testing per MIL-PRF-38535 Class Q. This makes it suitable for engine bay and transmission control unit deployments where ambient temperatures exceed 105°C.
Does the 5962-9751402QPA support true rail-to-rail input operation?
No-the 5962-9751402QPA features rail-to-rail *output* swing and an extended common-mode input range (0 V to 4.5 V min with 5-V supply), but it does not provide rail-to-rail *input* capability. Its input stage operates down to VDD– (ground) but requires ≥0.8 V headroom from VDD+ for linear operation, as specified in the recommended operating conditions.
Can the 5962-9751402QPA drive a 10 kΩ load while maintaining rail-to-rail output?
Yes-the 5962-9751402QPA maintains rail-to-rail output swing into 10 kΩ loads: at VDD = 5 V, VOH = 4.97 V and VOL = 0.04 V (typical) with IO = ±100 µA. Its 600-Ω drive rating refers to minimum load for guaranteed performance; lighter loads like 10 kΩ exhibit even better swing and settling behavior.
Is the 5962-9751402QPA pin-compatible with other TLV2422 variants?
No-the 5962-9751402QPA uses a 20-pin ceramic flat-pack (U) package with numerous NC pins, whereas standard TLV2422 variants use 8-pin SOIC (D), TSSOP (PW), or ceramic DIP (JG) packages. Pin mapping, footprint, and thermal characteristics differ significantly; PCB redesign is required for substitution.
What is the input offset voltage drift specification for the 5962-9751402QPA over temperature?
The 5962-9751402QPA has a temperature coefficient of input offset voltage (αVIO) of 2 µV/°C across its full operating range (–40°C to +125°C). This means offset can drift up to ±330 µV over the full temperature span, remaining well within the 950 µV max limit at 25°C and supporting stable performance in automotive thermal environments.
