Product details
Overview
LMH6733MQ/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 small-signal bandwidth at unity gain (±5V), 650 MHz at AV = +2 (5V), 3750 V/µs slew rate, and 2.1 nV/√Hz input voltage noise - enabling use in HDTV component video drivers, flash ADC front-ends, and radar IF amplifiers.
For engineers reviewing the LMH6733MQ/NOPB datasheet, LMH6733MQ/NOPB pinout, LMH6733MQ/NOPB application, or LMH6733MQ/NOPB equivalent, key selection criteria include its flow-through 16-pin SSOP pinout, individual shutdown pins per channel, ±1 to ±10 gain range without external compensation, and rail-to-rail output swing (1 V from each supply rail) on 3–12 V single or ±1.5–±6 V split supplies.
Technical Context
The LMH6733MQ/NOPB employs TI's current-feedback architecture with low-impedance inverting input (~30 Ω) and high-impedance non-inverting input (~200 kΩ), enabling stable unity-gain operation and bandwidth independence from closed-loop gain when using appropriate feedback resistors (e.g., 340 Ω at AV = +2). Its three independent amplifiers share no internal ground reference, supporting flexible single- or dual-supply configurations.
Each channel features dedicated DISx control pins with defined enable/disable thresholds (VDMIN = 3.6 V, VDMAX = 3.2 V), 10 ns enable/disable timing, and >70 mA linear output current into 100 Ω loads. Crosstalk between channels is −80 dB (input-referred, 10 MHz), confirming isolation suitable for multi-channel timing-critical systems.
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 without attenuation |
| Slew Rate | 3750 V/µs - enables clean 2 V step response in ≤0.7 ns (10%–90%), critical for pulse fidelity in radar receivers |
| Input Noise Voltage | 2.1 nV/√Hz above 10 MHz - preserves SNR in wide-dynamic-range applications like DDS post-amplification |
| Output Swing | ±3.7 V into 100 Ω on ±5V supplies (1.3 V from rails) - ensures full utilization of 10-bit+ ADC input ranges |
| Supply Current | 18 mA typical (all three amps enabled, 5V) - 5.5 mA per amplifier, enabling low-power triple-channel buffering |
| CMIR | ±4.0 V on ±5V supplies (CMRR > 43 dB) - accommodates large common-mode transients in line-driver interfaces |
| Crosstalk | −80 dB input-referred at 10 MHz - prevents inter-channel interference in multi-path analog signal chains |
Pinout & Package
The LMH6733MQ/NOPB is housed in a 16-pin SSOP package (Package Number DBQ0016A) with flow-through pinout optimized for minimal trace length and reduced parasitic coupling in high-frequency layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | −IN A | Inverting input of Channel A; low-impedance node (~30 Ω) requiring controlled-impedance routing |
| 2 | +IN A | Non-inverting input of Channel A; high-impedance node (~200 kΩ), sensitive to stray capacitance |
| 3 | −IN B | Inverting input of Channel B; electrically isolated from Channel A/C with −80 dB crosstalk |
| 4 | +IN B | Non-inverting input of Channel B; supports independent DC biasing per channel |
| 5 | DIS B | Active-high shutdown control for Channel B; enables <1.8 mA quiescent current per disabled channel |
| 6 | DIS C | Active-high shutdown control for Channel C; independent of Channels A/B for power-gating flexibility |
| 7 | −IN C | Inverting input of Channel C; identical impedance and layout rules as Pins 1 and 3 |
| 8 | +IN C | Non-inverting input of Channel C; allows three independent gain stages on one die |
| 9 | −VS | Negative supply rail; must be decoupled locally with 0.1 µF ceramic capacitor |
| 10 | OUT C | Output of Channel C; capable of ±70 mA linear current into 100 Ω loads |
| 11 | +VS | Positive supply rail; shared by all three amplifiers; requires low-ESR bulk + local ceramic decoupling |
| 12 | OUT B | Output of Channel B; flow-through layout minimizes adjacent-output coupling |
| 13 | −VS | Second negative supply connection; reduces ground bounce in high-current switching |
| 14 | OUT A | Output of Channel A; supports video-level drive (1 VPP, 75 Ω) with <0.03% differential gain error |
| 15 | +VS | Second positive supply connection; improves PSRR and thermal stability under load |
| 16 | DIS A | Active-high shutdown control for Channel A; enables per-channel power management in battery-sensitive designs |
Key Features
| Feature | Design Value |
|---|---|
| Current-feedback architecture | Enables stable unity-gain operation and bandwidth retention across AV = ±1 to ±10 without external compensation |
| Individual channel shutdown | Three independent DIS pins allow dynamic power scaling - reducing total ICC from 18 mA to ~2.5 mA with two channels off |
| Rail-to-rail output swing | Delivers 1.12–3.89 V output on 5V supply (1.12 V from V−, 1.11 V from V+), maximizing dynamic range in single-supply systems |
| Low distortion at 10 MHz | HD2 = −72 dBc, HD3 = −63 dBc (±5V, 2 VPP) - meets broadcast-grade video and communications spectral purity requirements |
| Flow-through SSOP pinout | Minimizes signal path length and crosstalk; eliminates need for layer transitions or vias in high-frequency PCB routing |
| High PSRR/CMRR | +PSRR = 61.5 dB, CMRR = 55 dB (±5V) - maintains accuracy in noisy industrial or automotive power environments |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6738MQ/NOPB | Pin-compatible 16-pin SSOP; identical pinout and electrical specs but rated for −40°C to +125°C (vs. +85°C for LMH6733MQ/NOPB) | Required for extended-temperature industrial or automotive under-hood use; same layout and BOM except temperature grade | Select LMH6738MQ/NOPB when operating ambient exceeds +85°C or AEC-Q100 qualification is needed |

FAQ
What supply voltage ranges does the LMH6733MQ/NOPB support?
The LMH6733MQ/NOPB operates from 3 V to 12 V single supply or ±1.5 V to ±6 V split supply. At ±5 V, it achieves 1.0 GHz −3 dB bandwidth and ±3.7 V output swing into 100 Ω. The device maintains specified performance across the full operating temperature range of −40°C to +85°C, with absolute maximum supply voltage of 13.2 V (V+ − V−).
Does the LMH6733MQ/NOPB require external compensation for unity-gain stability?
No, the LMH6733MQ/NOPB does not require external compensation for unity-gain stability. Its current-feedback architecture provides inherently stable operation across gains of ±1 to ±10 when used with recommended feedback resistors (e.g., 340 Ω at AV = +2). This eliminates the need for compensation capacitors or complex loop tuning in standard configurations.
How is channel shutdown implemented on the LMH6733MQ/NOPB?
Each channel of the LMH6733MQ/NOPB has a dedicated active-high disable pin (DIS A, DIS B, DIS C). A logic-high signal ≥3.6 V enables the channel; ≤3.2 V disables it. When disabled, supply current drops to ≤1.8 mA per channel, and output enters high-impedance state. Enable/disable timing is 10 ns and 15 ns respectively, supporting fast power cycling in burst-mode systems.
What is the input impedance profile of the LMH6733MQ/NOPB?
The LMH6733MQ/NOPB exhibits asymmetric input impedance: the inverting input presents ~30 Ω (output impedance of internal buffer), while the non-inverting input is ~200 kΩ with 1 pF capacitance. This current-feedback structure mandates careful attention to feedback resistor selection (e.g., 340 Ω at AV = +2) and minimizes sensitivity to gain-setting resistor tolerance.
Can the LMH6733MQ/NOPB drive 75 Ω video loads directly?
Yes, the LMH6733MQ/NOPB can drive 75 Ω video loads directly. In AC-coupled single-supply configurations (e.g., +5 V), it delivers 0.03% differential gain and 0.025° differential phase error at 4.43 MHz - meeting broadcast video standards. Output swing reaches ±3.55 V into 100 Ω and maintains linearity up to ±70 mA, supporting robust 75 Ω back-terminated driving.
