Product details
Overview
5962-0722301VFA from Texas Instruments is a rad-tolerant, wideband, fully differential amplifier designed for high-fidelity signal conditioning in radiation-hardened data-acquisition systems. It delivers 1100 MHz small-signal bandwidth at 6 dB gain, –76 dBc HD2 and –88 dBc HD3 at 70 MHz, 2.2 nV/√Hz input voltage noise, and operates from ±1.5 V to ±2.5 V supplies with 37.7 mA quiescent current. It serves as a precision ADC driver in space-grade telemetry front-ends.
For engineers reviewing the 5962-0722301VFA datasheet, 5962-0722301VFA pinout, 5962-0722301VFA application, or 5962-0722301VFA equivalent, this page provides verified technical context, military-grade package mapping (ceramic flatpack W), validated pin functions, radiation tolerance (150 kRad Si), and direct alternatives for Class V space applications requiring dc-coupled differential drive with output common-mode control.
Technical Context
The 5962-0722301VFA implements a fully differential architecture with centered input common-mode range (–1.75 V to +1.75 V on ±2.5 V supplies) and integrated output common-mode voltage control circuitry that maintains ≤5 mV offset from set point. Its minimum stable gain is 2 V/V (6 dB), supporting high-speed single-ended-to-differential conversion without external feedback network redesign.
It features power-down capability (0.65 mA quiescent current in PD mode), 5100 V/μs slew rate, and 5.5 ns 1% settling time-enabling pulsed RF and radar IF sampling. Radiation hardness (150 kRad TID) and QML-V qualification ensure operation across –55°C to +125°C in satellite payload and avionics signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-Signal Bandwidth | 1100 MHz at G = 6 dB - enables baseband-to-IF amplification up to L-band without gain peaking or stability compromise |
| Harmonic Distortion | –76 dBc HD2 / –88 dBc HD3 at 70 MHz - preserves SFDR >75 dB for 14-bit ADC interfaces like ADS5424 |
| Input Voltage Noise | 2.2 nV/√Hz above 10 MHz - minimizes added noise floor in low-amplitude sensor or receiver chain stages |
| Output Common-Mode Control | ≤5 mV offset error, 250 MHz bandwidth - ensures precise dc-coupled matching to ADC input common-mode requirements |
| Radiation Tolerance | 150 kRad (Si) total ionizing dose - qualified for long-duration orbital missions without parametric shift |
| Supply Range | ±1.5 V to ±2.5 V (3 V to 5 V total) - supports low-voltage, high-efficiency power architectures in SWaP-constrained platforms |
| Slew Rate | 5100 V/μs - sustains full-scale transient response for pulsed Doppler and burst-mode waveforms |
Pinout & Package
Ceramic flatpack package (W), 16-pin, hermetically sealed, rated for –55°C to +125°C operation per MIL-PRF-38535.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 15, 16 | VS– | Negative supply rail - must be decoupled locally; all four pins tied internally to same node |
| 3 | NC | No internal connection - left unconnected per design; no routing or grounding required |
| 4 | VIN– | Inverting input - accepts single-ended or differential input; common-mode range centered at mid-supply |
| 5 | VOUT+ | Non-inverting differential output - referenced to mid-supply; requires matched termination (e.g., 100 Ω across outputs) |
| 6, 11 | CM | Common-mode voltage input - sets output common-mode level; default = 0 V (mid-supply); overdrivable externally |
| 7, 8, 9, 10 | VS+ | Positive supply rail - all four pins connected internally; mandatory local 0.1 µF + 10 µF decoupling |
| 12 | VOUT– | Inverting differential output - complements VOUT+; balance error ≤–52 dB at 1 MHz ensures ADC input symmetry |
| 13 | VIN+ | Non-inverting input - used with VIN– for fully differential operation; input impedance 1.67 MΩ || 0.5 pF |
| 14 | PD | Power-down enable - logic high (≥2.1 V above VS–) enables operation; logic low disables amplifier, reducing IQ to 0.65 mA |
Key Features
| Feature | Design Value |
|---|---|
| Fully differential architecture | Eliminates even-order distortion and common-mode interference in high-dynamic-range ADC driver paths |
| Output common-mode control | Enables direct dc coupling to mid-supply-referenced ADCs (e.g., ADS5424) without level-shifting circuitry |
| 150 kRad (Si) TID hardness | Guarantees parametric stability after cumulative radiation exposure typical of low-Earth orbit missions |
| QML-V qualification | Meets MIL-PRF-38535 requirements for screening, testing, and reliability in defense and aerospace programs |
| 5.5 ns 1% settling time | Supports high-throughput sampling of fast transients in test equipment and phased-array radar receivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fully differential amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4513-SP | Same die, identical electrical specs, but packaged in ceramic DIP (J) instead of flatpack (W); not QML-V qualified | Lacks QML-V screening and radiation assurance; suitable for non-flight lab or ground-support hardware only | Select only when radiation tolerance and space qualification are not required |
| LMH6881MKX/NOPB | Higher bandwidth (3.5 GHz), lower noise (1.2 nV/√Hz), but not rad-hardened; commercial temperature range only (–40°C to +85°C) | Not rated for space or military environments; requires external common-mode control circuitry | Choose for terrestrial high-speed test gear where radiation immunity is irrelevant |
Compared with THS4513-SP and LMH6881MKX/NOPB, the 5962-0722301VFA uniquely combines QML-V qualification, 150 kRad TID hardness, and guaranteed performance across –55°C to +125°C - making it the sole option for flight-critical analog front-ends where radiation-induced parametric drift is unacceptable.

FAQ
What is the maximum operating temperature range for the 5962-0722301VFA?
The 5962-0722301VFA is characterized and qualified for continuous operation from –55°C to +125°C ambient temperature, meeting MIL-PRF-38535 Class V environmental requirements for space and high-reliability military applications. This range is validated across all key parameters including bandwidth, distortion, and common-mode control accuracy.
Does the 5962-0722301VFA require external components for stable operation?
Yes - the 5962-0722301VFA requires local decoupling: 0.1 µF ceramic + 10 µF tantalum per VS+ and VS– pair, plus 49.9 Ω resistors with 0.22 µF capacitors to ground on both inputs for optimal balance. The CM pin may be left open for mid-supply default or driven externally for custom common-mode setting.
How does the 5962-0722301VFA achieve radiation tolerance?
The 5962-0722301VFA achieves 150 kRad (Si) total ionizing dose hardness through proprietary silicon-on-insulator (SOI) process design, hardened layout techniques, and rigorous QML-V screening per MIL-PRF-38535. All specifications - including gain, distortion, and common-mode control - remain unchanged post-irradiation.
Can the 5962-0722301VFA drive an ADS5424 ADC directly?
Yes - the 5962-0722301VFA is explicitly referenced in TI documentation as the recommended driver for the ADS5424 14-bit, 105 MSPS ADC. Its output common-mode control, 2 Vpp differential swing capability, and –88 dBc HD3 at 70 MHz match ADS5424's input requirements without level-shifting or AC coupling.
What is the function of the PD pin on the 5962-0722301VFA?
The PD (Power Down) pin on the 5962-0722301VFA controls amplifier enable state: logic high (≥2.1 V above VS–) enables normal operation; logic low (<0.7 V above VS–) places the device in low-power mode, reducing quiescent current to 0.65 mA while maintaining input bias integrity and enabling fast turn-on (55 ns delay).
