Product details
Overview
LMH6733MQX/NOPB from Texas Instruments is a triple, current-feedback operational amplifier optimized for high-speed video and wideband signal conditioning. It delivers 1.0 GHz −3 dB bandwidth at unity gain (±5V), 650 MHz at AV = +2 (5V), 3750 V/µs slew rate, 2.1 nV/√Hz input voltage noise, and individual shutdown pins per channel - enabling use in HDTV component video drivers and flash ADC front-ends.
For engineers reviewing the LMH6733MQX/NOPB datasheet, LMH6733MQX/NOPB pinout, LMH6733MQX/NOPB application, or LMH6733MQX/NOPB equivalent, key selection criteria include its current-feedback architecture, flow-through 16-pin SSOP pinout, rail-to-rail output swing (1 V from rails), ±1 to ±10 gain range without external compensation, and 5.5 mA per amplifier supply current at 5V.
Technical Context
The LMH6733MQX/NOPB implements a current-feedback topology with low-impedance inverting input (~30 Ω) and high-impedance non-inverting input (~200 kΩ), enabling stable operation across gains ±1 to ±10 using fixed RF values (e.g., 340 Ω at AV = +2). Its bandwidth scales inversely with feedback resistance, not closed-loop gain - distinguishing it from voltage-feedback amplifiers.
Each of the three independent amplifiers features dedicated DIS pins (DIS A/B/C), allowing selective channel shutdown with 10 ns enable/disable timing. The device operates from single 3–12 V or split ±1.5 V to ±6 V supplies, with CMIR extending to 1.0–4.0 V (single) or ±3.8 V (split) and output swing to within 1 V of each rail under 100 Ω load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 1.0 GHz at AV = +1, ±5V supply - supports baseband video and IF signals up to UHF. |
| Slew Rate | 3750 V/µs at ±5V - enables clean 2 VPP step response with 0.7 ns rise time (10–90%). |
| Input Voltage Noise | 2.1 nV/√Hz above 10 MHz - preserves SNR in wideband receiver chains and ADC drivers. |
| Supply Current | 5.5 mA per amplifier at 5V - total 16.7 mA typical for all three channels enabled. |
| Output Current | ±70 mA linear output drive into 100 Ω - sufficient for driving 75 Ω coax with back-termination. |
| CMIR / Output Swing | 1.0–4.0 V common-mode input range and 1.12–3.88 V output swing (RL = 100 Ω, 5V) - supports single-supply video DC-coupled interfaces. |
| Distortion (HD2/HD3) | −72 dBc / −63 dBc at 2 VPP, 10 MHz (±5V) - meets broadcast-grade differential gain/phase specs (0.03%/0.03°). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6738MM/NOPB | Pin-compatible 16-pin SSOP triple CFA; identical pinout and electrical specs but rated for −40°C to +125°C industrial temp range. | Required for extended temperature environments (e.g., automotive infotainment, outdoor AV enclosures). | Select LMH6738MM/NOPB when operating ambient exceeds +85°C or MIL-STD-810 thermal cycling is required. |
| THS3201DGN | Single-channel, 1.8 GHz CFA in 8-pin MSOP; higher bandwidth but no integrated shutdown and different gain-setting behavior. | Used where only one high-speed channel is needed and board space is constrained. | Choose THS3201DGN for ultra-wideband single-channel designs; avoid for triple-channel or per-channel power gating needs. |
Compared with LMH6733MQX/NOPB, LMH6738MM/NOPB offers extended temperature rating without layout change, while THS3201DGN trades channel count and shutdown for higher bandwidth and smaller footprint - making LMH6733MQX/NOPB optimal for cost-sensitive, triple-channel, single-supply video and instrumentation systems.

FAQ
What supply voltage ranges does the LMH6733MQX/NOPB support?
The LMH6733MQX/NOPB operates from single 3 V to 12 V or split ±1.5 V to ±6 V supplies. Absolute maximum supply voltage is 13.2 V (V+ − V−). At 5 V single supply, it delivers 650 MHz bandwidth and 5.5 mA per amplifier quiescent current. The device has no internal ground reference, enabling flexible configuration in either supply mode without performance penalty.
Does the LMH6733MQX/NOPB require external compensation for unity-gain stability?
No, the LMH6733MQX/NOPB does not require external compensation for unity-gain stability. Its current-feedback architecture provides inherently stable operation across gains ±1 to ±10 using appropriate feedback resistors (e.g., 340 Ω at AV = +2). The datasheet confirms stable 1.0 GHz −3 dB bandwidth at AV = +1 with ±5 V supplies and no added components.
How is channel shutdown implemented on the LMH6733MQX/NOPB?
Each amplifier in the LMH6733MQX/NOPB has a dedicated active-high shutdown pin: DIS A (Pin 16), DIS B (Pin 5), and DIS C (Pin 6). Driving a DIS pin ≥3.6 V enables the corresponding amplifier; ≤3.2 V disables it. Enable/disable timing is 10 ns and 15 ns respectively, and disabled channels draw ≤1.8 mA total supply current - enabling dynamic power optimization in multi-stage signal paths.
What is the recommended feedback resistor for AV = +2 configuration with LMH6733MQX/NOPB?
The recommended feedback resistor for AV = +2 is 340 Ω with 5 V supply and 383 Ω with ±5 V supply, as specified in the Electrical Characteristics tables and Typical Performance plots. These values optimize bandwidth, flatness, and stability. Deviating significantly (e.g., <250 Ω or >450 Ω) causes peaking, ringing, or reduced bandwidth - confirmed by Figure 36 (RF vs. Gain) and Application Information section.
Can the LMH6733MQX/NOPB drive 75 Ω coaxial cable directly?
Yes, the LMH6733MQX/NOPB can drive 75 Ω coax directly using a back-termination configuration: place a 75 Ω resistor (RO) in series with the output, then connect the load to ground. This eliminates reflections while maintaining signal integrity. The amplifier's ±70 mA linear output current and 0.05 Ω DC output impedance ensure minimal droop, and Figure 40 in the datasheet validates this topology for component video transmission.
