Product details
Overview
5962-0721901VHA from Texas Instruments is a radiation-hardened, high-reliability wideband operational amplifier in a 10-terminal flatpack (CDFP2-F10/GDFP1-F10), delivering ±80 mA output current at ±2.5 V supply, 78 dB CMRR, and operation from –55°C to +125°C - used in precision analog front-ends of military radar receivers and spaceborne telemetry conditioning circuits.
For engineers reviewing the 5962-0721901VHA datasheet, 5962-0721901VHA pinout, 5962-0721901VHA application, or 5962-0721901VHA equivalent, key selection criteria include radiation hardness assurance (RHA), MIL-PRF-38535 Class V qualification, dual-supply operation down to ±1.35 V, thermal performance up to +125°C ambient, and no-connection terminal layout for PCB isolation in high-noise environments.
Technical Context
This device implements a monolithic silicon wideband op-amp architecture optimized for low-noise, high-slew-rate signal conditioning under extreme temperature and radiation exposure. It supports dual ±1.35 V to ±2.75 V and single +2.7 V to +5 V supply configurations with rail-to-rail input common-mode range extending ±0.2 V beyond rails.
Designed for Class V space applications, it meets MIL-STD-883 screening requirements including burn-in, life test, and post-irradiation parameter verification. Its 14.7°C/W θJC enables direct heatsinking in hermetic flatpacks, while ESD ratings (1600 V HBM, 1000 V CDM) support handling in cleanroom assembly lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±1.35 V to ±2.75 V dual; enables low-voltage precision amplification in battery-constrained avionics systems |
| Output Current (Sourcing) | ±80 mA at ±2.5 V (RL = 10 Ω); drives low-impedance loads like ADC drivers or RF mixer bias networks |
| CMRR | 78 dB at ±1 V common-mode swing; rejects power supply noise in mixed-signal sensor interfaces |
| Quiescent Current | 17.5–18.9 mA at ±2.5 V; balances speed and power in thermally constrained satellite payloads |
| Operating Temperature | –55°C to +125°C ambient; qualified per MIL-PRF-38535 for extended-life deployment in orbital and deep-terrain platforms |

Equivalent & Alternatives
The following parts are listed as comparable options for similar wideband operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-0721901QHA | Same die, Class Q (high-reliability) instead of Class V; lower RHA assurance level, no space radiation testing | Approved for ground-based military systems but not certified for orbital deployment | Select when radiation hardness is not required and cost sensitivity favors non-space-qualified sourcing |
| OPA656UB | Commercial-grade, non-RHA, SOIC-8 package; 230 MHz GBW vs. 1.5 GHz (THS4304M core), no MIL-STD-883 screening | Limited to benign environments; lacks thermal/radiation qualification and hermetic packaging | Use only for lab prototyping or non-critical commercial subsystems where Class V compliance is unnecessary |
Compared with 5962-0721901VHA, the 5962-0721901QHA offers identical electrical performance but omits space-level radiation testing, while the OPA656UB trades hermeticity, screening, and RHA for lower cost and surface-mount convenience - neither is pin-compatible nor drop-in replaceable due to differing pin count, package, and qualification scope.

FAQ
What is the radiation hardness assurance (RHA) level certified for 5962-0721901VHA?
The 5962-0721901VHA is certified to MIL-PRF-38535 Class V radiation hardness assurance, meeting Appendix B requirements for total ionizing dose (TID) tolerance in space applications. Its RHA designator "V" confirms qualification for orbital deployment, with post-irradiation parameter verification performed per Table IIA test subgroups 1–3 at +25°C.
Does 5962-0721901VHA support single-supply operation?
Yes, 5962-0721901VHA supports single-supply operation from +2.7 V to +5 V, as specified in Section 1.4 of the drawing. Its input common-mode range extends to –VS – 0.2 V, enabling ground-referenced inputs even in single-supply configurations - a key feature for interfacing with sensors in portable military equipment.
What is the meaning of the "H" in the part number 5962-0721901VHA?
The "H" in 5962-0721901VHA denotes the case outline per MIL-STD-1835: specifically, a 10-terminal flatpack (CDFP2-F10 or GDFP1-F10). This hermetic ceramic package provides mechanical robustness, thermal stability, and moisture resistance essential for long-duration deployment in aerospace and defense platforms.
Can 5962-0721901VHA be used in place of commercial op-amps like THS4304DRG4?
No - 5962-0721901VHA is not a direct replacement for THS4304DRG4. While both share the THS4304M core, 5962-0721901VHA features MIL-PRF-38535 Class V qualification, hermetic flatpack packaging, 10-pin layout with NC terminals, and radiation testing. The DRG4 is a commercial SOIC-8 variant lacking screening, RHA, or military temperature range validation.
What thermal management guidance applies to 5962-0721901VHA in high-power operation?
For reliable operation, keep the junction temperature ≤ +125°C. With θJC = 14.7°C/W and θJA = 189°C/W, use direct heatsinking via pins 5 (–VS) and 8 (+VS), maintain ≥ 1 cm² copper pour per supply pin, and limit continuous dissipation to 344 mW at +85°C ambient - as defined in Absolute Maximum Ratings (Sheet 3).
