Product details
Overview
LMH6702WGFLQMLV from Texas Instruments is a radiation-hardened, current-feedback operational amplifier designed for ultra-wideband, low-distortion signal conditioning in space-grade radar and high-speed data acquisition systems. It delivers 720MHz −3dB bandwidth (AV = +2, VOUT = 0.2VPP), 1.83nV/√Hz input voltage noise, 3100V/μs slew rate, 13.4ns 0.1% settling time, and −67dBc intermodulation distortion at 75MHz - enabling precision drive of 10-bit+ flash ADCs in demanding RF front-ends.
For engineers reviewing the LMH6702WGFLQMLV datasheet, LMH6702WGFLQMLV pinout, LMH6702WGFLQMLV application, or LMH6702WGFLQMLV equivalent, this page provides verified radiation-tolerant op amp specifications, CDIP/NAB and CFP/NAC package mapping, validated pin functions, and direct alternatives for space-qualified wideband amplifier selection.
Technical Context
The LMH6702WGFLQMLV employs TI's VIP10 complementary bipolar process and current-feedback architecture, achieving unity-gain stability without external compensation while maintaining exceptional signal fidelity across DC to 720MHz. Its transimpedance gain structure decouples bandwidth from closed-loop gain, enabling consistent high-speed performance across AV = ±1 to ±10 configurations.
Designed explicitly for high-dynamic-range analog signal chains, it supports operation from −55°C to +125°C with radiation assurance up to 300krad(Si) high-dose-rate and ELDRS-free qualification. Input bias currents remain stable post-irradiation, and supply rejection exceeds 45dB across ±5V to ±6V operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3dB Bandwidth | 720MHz at AV = +2, VOUT = 0.2VPP - enables baseband-to-IF amplification through L/S-band without gain peaking. |
| Slew Rate | 3100V/μs - supports full-scale 2VPP output transitions in under 0.65ns, critical for fast-settling ADC driver stages. |
| Input Voltage Noise | 1.83nV/√Hz - preserves SNR in low-level signal paths such as radar receiver IF amplifiers and video line drivers. |
| Settling Time | 13.4ns to 0.1% - ensures accurate sampling window alignment for ≥100MSPS flash ADCs with minimal aperture error. |
| Intermodulation Distortion | −67dBc at 75MHz (two-tone test) - maintains spectral purity in wideband communication receivers and spectrum analyzers. |
| Supply Current | 12.5mA typical at ±5V - balances power efficiency with ultra-high speed in thermally constrained space payloads. |
| Radiation Tolerance | 300krad(Si) total ionizing dose, ELDRS-free - qualified per MIL-STD-883 for long-duration orbital missions. |
Pinout & Package
LMH6702WGFLQMLV is supplied in the NAC (10-pin CFP) hermetic ceramic flatpack package, measuring 9.91mm × 6.45mm. This military/aerospace-grade package provides superior thermal dissipation (θJC = 37°C/W) and hermetic sealing for space and high-reliability applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | N/C | No internal connection; electrically isolated - must be left floating or tied to ground only if required by layout EMI mitigation. |
| 2 | +VCC | Positive supply terminal - requires dedicated low-ESR decoupling (e.g., 6.8µF tantalum + 0.01µF ceramic) referenced to local ground plane. |
| 3 | VOUT | Amplifier output - drives resistive loads ≥100Ω or capacitive loads via series resistor (RS) to suppress ringing per Figure 5-10. |
| 4 | N/C | No internal connection - no routing or bonding; avoid PCB trace stubs to prevent parasitic resonance. |
| 5 | N/C | No internal connection - same isolation requirements as Pin 1 and Pin 4. |
| 6 | N/C | No internal connection - unused pin; do not connect to supply or signal nets. |
| 7 | VNON-INV | Non-inverting input - high-impedance node; requires symmetric trace routing and guard ring to minimize common-mode pickup. |
| 8 | −VCC | Negative supply terminal - mirror-decoupled to +VCC; star-ground connection mandatory for HD2 minimization. |
| 9 | VINV | Inverting input - current-input node in CFB topology; impedance matching to feedback network (RF = 237Ω) is critical for stability. |
| 10 | N/C | No internal connection - fully isolated; PCB pad may be used for mechanical anchoring only. |
Key Features
| Feature | Design Value |
|---|---|
| Current-feedback architecture | Enables constant 720MHz bandwidth across AV = ±1 to ±10 without external compensation - simplifies gain-setting in multi-stage IF chains. |
| ELDRS-free 300krad(Si) tolerance | Guarantees parametric stability after exposure to high-dose-rate space radiation environments - eliminates need for derating or burn-in screening. |
| Low 2nd-harmonic distortion | −52dBc at 20MHz (2VPP) - achieved via split ground plane layout and optimized supply decoupling, critical for NTSC/PAL video fidelity. |
| High output current drive | 80mA continuous - supports direct driving of 100Ω transmission lines or parallel ADC inputs without external buffers. |
| DC-coupled wideband response | Operates from DC to 720MHz - eliminates AC-coupling capacitors in radar pulse amplifiers and high-resolution imaging signal paths. |
Applications
| Radar Pulse Amplifier | Flash ADC Driver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar wideband, radiation-tolerant op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6703QML-SP | Higher 1.2GHz bandwidth but higher 2.2nV/√Hz noise and 15mA supply current; identical NAC package and radiation spec. | Better suited for >1GHz IF stages where noise penalty is acceptable; less optimal for low-noise ADC driving below 500MHz. | Select LMH6703QML-SP only when bandwidth >1GHz is mandatory and system SNR budget allows +0.4nV/√Hz noise increase. |
| CLC449MJ/883 | Legacy BiFET amplifier with 400MHz bandwidth, higher 3.5nV/√Hz noise, and no ELDRS-free qualification; CDIP-8 package. | Proven in older flight hardware but lacks modern distortion performance and radiation assurance rigor of LMH6702WGFLQMLV. | Use CLC449MJ/883 only for legacy redesigns requiring form-fit-function replacement without requalification; not recommended for new designs. |
Compared with LMH6702WGFLQMLV, LMH6703QML-SP trades noise and power for bandwidth headroom, while CLC449MJ/883 offers backward compatibility at the cost of signal fidelity and modern radiation assurance - making LMH6702WGFLQMLV the optimal balance for new high-dynamic-range space electronics.

FAQ
What is the maximum operating supply voltage for LMH6702WGFLQMLV?
The LMH6702WGFLQMLV has an absolute maximum supply voltage rating of ±6.75VDC. For reliable operation, TI specifies recommended conditions of ±5VDC to ±6VDC. Exceeding ±6.75V risks permanent damage to the VIP10 bipolar die; operation at ±6V is permissible but increases power dissipation and thermal stress in the NAC package.
Does LMH6702WGFLQMLV require external compensation for stability?
No, the LMH6702WGFLQMLV does not require external compensation due to its current-feedback architecture and internal optimization for unity-gain stability. The device remains stable across AV = ±1 to ±10 with the recommended 237Ω feedback resistor. Deviating from RF = 237Ω may induce peaking or ringing, as documented in TI Application Note OA-13.
What is the radiation qualification level of LMH6702WGFLQMLV?
The LMH6702WGFLQMLV is qualified to 300krad(Si) total ionizing dose under high-dose-rate conditions and is ELDRS-free per MIL-STD-883 Method 1019. It undergoes full Group A testing (subgroups 1–11) across −55°C to +125°C, with pre- and post-irradiation electrical verification confirming parameter stability.
Which package does LMH6702WGFLQMLV use, and what are its key mechanical properties?
LMH6702WGFLQMLV uses the NAC (10-pin Ceramic Flatpack) package, measuring 9.91mm × 6.45mm with hermetic ceramic construction. It features θJC = 37°C/W, θJA = 220°C/W (still air), and a mass of 227mg - optimized for thermal management and reliability in vacuum and thermal-cycling space environments.
How does LMH6702WGFLQMLV differ from commercial-grade LMH6702 variants?
LMH6702WGFLQMLV differs from commercial LMH6702 versions in radiation hardening (300krad(Si), ELDRS-free), extended temperature range (−55°C to +125°C), hermetic NAC packaging, MIL-STD-883 screening, and tighter drift specifications (e.g., ±1.0mV VIO drift over temperature). Commercial variants lack radiation testing, use plastic SOIC or SOT-23 packages, and operate only to +85°C.
