Product details
Overview
5962-9751402QHA from Texas Instruments is a Q-Temp automotive-grade dual rail-to-rail output operational amplifier optimized for micropower, wide-input-voltage operation. It delivers 50 µA per channel supply current, 950 µV max input offset voltage (at 25°C), 1 pA typical input bias current, and rail-to-rail output swing with 5-V single-supply operation - enabling precision signal conditioning in battery-powered automotive sensor interfaces.
For engineers reviewing the 5962-9751402QHA datasheet, 5962-9751402QHA pinout, 5962-9751402QHA application, or 5962-9751402QHA equivalent, key selection criteria include its –40°C to 125°C operating range, guaranteed low-offset performance across temperature, no phase inversion at rail inputs, 600-Ω output drive capability, and qualification to automotive reliability standards.
Technical Context
The 5962-9751402QHA implements Advanced LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typ) and high input impedance (>1012 Ω), making it suitable for interfacing with high-impedance sources like piezoelectric transducers and resistive sensors. Its extended common-mode input voltage range (0 V to 4.5 V min on 5-V supply) eliminates phase inversion near supply rails - a critical advantage over standard CMOS op-amps in single-supply systems.
This device is fully characterized at 3-V and 5-V supplies, with rail-to-rail output enabling full dynamic range utilization when driving ADCs or low-voltage logic. The 18 nV/√Hz input voltage noise at 1 kHz and 0.008 V/µs slew rate support low-frequency precision applications without bandwidth compromise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports wide-input-voltage operation in automotive 3.3-V and 5-V domains with headroom for transient conditions. |
| Input Offset Voltage (max) | 950 µV at 25°C - enables accurate DC-coupled amplification in precision sensor front-ends without trimming. |
| Supply Current per Channel | 100–150 µA typ at 25°C - ensures micropower operation for always-on vehicle subsystems and remote sensing nodes. |
| Input Bias Current (typ) | 1 pA - preserves signal integrity from high-impedance sources such as thermistors and pH electrodes. |
| Output Drive Capability | ±50 mA short-circuit current; drives 600-Ω loads - sufficient for telecom line drivers and analog output stages. |

Ceramic flat-pack (U) package with 20-pin configuration, hermetically sealed for high-reliability automotive use.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7, 9, 11, 13, 15, 17, 19 | No internal connection (NC) | Unused pins; must remain unconnected to avoid parasitic coupling or mechanical stress. |
| 2 | Amplifier 2 Output | Rail-to-rail output capable of sourcing/sinking ±50 mA; connects directly to ADC input or load. |
| 4 | Amplifier 2 Inverting Input | High-impedance node (1012 Ω); requires guarded layout to minimize leakage-induced offset. |

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 TSSOP-8 package; not hermetically sealed; rated –40°C to 125°C but not MIL-PRF-38535 qualified. | Suitable for non-safety-critical automotive modules (e.g., infotainment) where cost and PCB area are prioritized over hermetic reliability. | Select 5962-9751402QHA for ASIL-B/C systems requiring certified screening; TLV2422AQD for cost-sensitive designs with equivalent electrical specs. |
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift vs. 2 µV/°C for 5962-9751402QHA; higher quiescent current (17 µA per amp). | Better for ultra-stable DC measurements (e.g., current shunt amplification), but less optimal for micropower always-on monitoring. | Choose 5962-9751402QHA when micropower and automotive qualification outweigh ultra-low drift; OPA2333AIDR when long-term DC accuracy dominates. |
Compared with TLV2422AQD and OPA2333AIDR, the 5962-9751402QHA uniquely combines MIL-qualified hermetic packaging, sub-1-mV offset, and 50-µA/channel consumption - making it the only option meeting simultaneous requirements for under-hood reliability, precision, and energy efficiency.

FAQ
What is the maximum operating temperature range for the 5962-9751402QHA?
The 5962-9751402QHA is specified for continuous operation from –40°C to +125°C ambient temperature. This range is validated per MIL-PRF-38535 Class Q requirements and includes full electrical characterization across the entire span - ensuring reliable performance in under-hood automotive environments such as engine control modules and transmission control units.
Does the 5962-9751402QHA support true rail-to-rail input operation?
No, the 5962-9751402QHA features rail-to-rail *output* swing but has an extended common-mode input voltage range from 0 V to VDD – 0.8 V (min). It does not include rail-to-rail input circuitry. However, its lack of phase inversion at the supply rails - combined with wide input range - provides functional advantages similar to rail-to-rail input op-amps in many single-supply applications.
Is the 5962-9751402QHA pin-compatible with other TLV2422 variants?
No - the 5962-9751402QHA uses a 20-pin ceramic flat-pack (U) package with multiple NC pins, whereas standard TLV2422 variants use 8-pin SOIC (D), TSSOP (PW), or CERDIP (JG) packages. Pin count, layout, and thermal characteristics differ significantly; PCB redesign is required for substitution.
What is the input offset voltage specification for the 5962-9751402QHA over temperature?
The 5962-9751402QHA (A-grade variant) guarantees a maximum input offset voltage of 1800 µV over its full operating range of –40°C to +125°C. At 25°C, the limit is tighter: 950 µV max. Its temperature coefficient is 2 µV/°C, enabling predictable drift modeling in precision calibration routines.
Can the 5962-9751402QHA drive a 10-kΩ load while maintaining rail-to-rail output?
Yes - the 5962-9751402QHA maintains rail-to-rail output swing into 10-kΩ loads across its full operating temperature range. Its closed-loop output impedance is 130 Ω at 100 kHz, and it delivers >4.25 V high-level and <0.5 V low-level output voltages on a 5-V supply with 500-µA load current - well within specifications for driving ADC inputs and logic interfaces.
