Product details
Overview
5962-9751401QPA from Texas Instruments is a Q-grade (–40°C to 125°C) dual rail-to-rail output operational amplifier in ceramic flatpack (U) package, featuring micropower operation (100–150 µA per channel), 5-V supply compatibility, 0 V to 4.5 V common-mode input range, and 950 µV max input offset voltage at 25°C. It serves precision signal conditioning in high-reliability automotive and aerospace sensor interfaces.
For engineers reviewing the 5962-9751401QPA datasheet, 5962-9751401QPA pinout, 5962-9751401QPA application, or 5962-9751401QPA equivalent, key selection criteria include its extended temperature qualification, rail-to-rail output swing into 600-Ω loads, low 18 nV/√Hz input noise at 1 kHz, absence of phase inversion, and suitability for interfacing with low-voltage ADCs in battery-constrained or harsh-environment systems.
Technical Context
The 5962-9751401QPA implements Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining wide common-mode input range (0 V to 4.5 V with 5-V supply) and no phase inversion - critical for sensor front-ends where inputs approach supply rails. Its dual-amplifier architecture supports independent signal paths without crosstalk degradation.
Designed for MIL-PRF-38535 Class Q compliance, it undergoes full characterization across –40°C to 125°C, with tested parameters including input offset voltage (≤950 µV), supply current (100–150 µA/channel), and output drive capability (±50 mA short-circuit, 600-Ω load compatible). It operates from 2.7 V to 10 V supplies and exhibits 70 dB minimum CMRR and 80 dB SVR.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333QPWRQ1 | Chopper-stabilized (0.02 µV/°C drift), lower offset (10 µV max), but higher quiescent current (17 µA/channel). | Better for ultra-low-drift DC applications; unsuitable for micropower or >100 kHz bandwidth needs. | Select when long-term DC accuracy outweighs power budget constraints. |
| LMV722QDRQ1 | Lower cost CMOS design, 1.8 V min supply, but only rated to 105°C and lacks MIL-PRF-38535 qualification. | Suitable for commercial automotive infotainment; not approved for safety-critical or flight hardware. | Select for cost-sensitive Tier-2 subsystems where extended temperature and military traceability are not required. |
Compared with 5962-9751401QPA, OPA2333QPWRQ1 trades micropower for chopper-based precision, while LMV722QDRQ1 sacrifices qualification rigor for cost and voltage flexibility - making 5962-9751401QPA uniquely suited for high-integrity analog signal chains where reliability, temperature margin, and rail-to-rail performance are non-negotiable.

FAQ
What is the maximum operating temperature range for the 5962-9751401QPA?
The 5962-9751401QPA is qualified for continuous operation from –40°C to 125°C per MIL-PRF-38535 Class Q requirements. All electrical parameters - including input offset voltage, supply current, and output drive - are fully tested across this range, making it suitable for under-hood automotive and avionics applications where thermal extremes are routine. The 5962-9751401QPA's ceramic flatpack (U) package ensures mechanical and thermal stability at peak temperatures.
Does the 5962-9751401QPA support rail-to-rail input operation?
No, the 5962-9751401QPA features rail-to-rail *output* swing but not rail-to-rail input. Its common-mode input voltage range extends from 0 V to 4.5 V (minimum) with a 5-V supply - meaning it accepts inputs down to ground and up to within 0.5 V of VDD+, but does not reach the positive rail. This design avoids phase inversion while balancing input stage headroom and power efficiency. The 5962-9751401QPA is explicitly characterized for no phase inversion when driven to the rails.
What is the typical input noise performance of the 5962-9751401QPA at 1 kHz?
The 5962-9751401QPA delivers 18 nV/√Hz typical equivalent input noise voltage at 1 kHz under 5-V supply conditions, as confirmed in the SLOS199C datasheet Section 12. This low-noise characteristic, combined with 1 pA typical input bias current and 10¹² Ω input resistance, makes the 5962-9751401QPA especially effective for amplifying weak signals from high-impedance sources such as piezoelectric sensors, pH electrodes, and medical biopotential transducers without degrading signal integrity.
Is the 5962-9751401QPA pin-compatible with other TLV2422 variants?
Yes - the 5962-9751401QPA uses the same 20-pin ceramic flatpack (U) footprint and pinout as other TLV2422M/TLV2422AM variants, including identical NC pin assignments and functional pin mapping (e.g., Pin 2 = OUT2, Pin 11 = OUT1, Pin 17 = VDD+). However, due to its Q-grade qualification and tighter offset specification (950 µV max), it is not a drop-in replacement for C- or I-suffix versions in commercial designs unless MIL-PRF-38535 compliance is also required.
Can the 5962-9751401QPA drive a 600-Ω load effectively?
Yes - the 5962-9751401QPA is explicitly specified to drive 600-Ω loads, as stated in the device description and verified by output voltage swing data: at 5-V supply and IOH = –1 mA, VOH ≥ 4.75 V (typical), and at IOL = 500 µA, VOL ≤ 0.15 V (typical). This capability enables direct interfacing with telecom line drivers, legacy ADC reference inputs, and instrumentation-grade signal chains without external buffer stages - a key differentiator versus many micropower op-amps.
