Product details
Overview
LT1206CR#TRPBF from Analog Devices (formerly Linear Technology) is a current-feedback operational amplifier optimized for high-current video and cable driving applications. It delivers 250mA minimum output drive, 60MHz small-signal bandwidth at AV = 2 with 100Ω load, 900V/µs slew rate, 0.02% differential gain, and 0.17° differential phase - enabling robust RGB, composite video, and multi-cable distribution in broadcast and test equipment.
For engineers reviewing the LT1206CR#TRPBF datasheet, LT1206CR#TRPBF pinout, LT1206CR#TRPBF application, or LT1206CR#TRPBF equivalent, key selection criteria include capacitive-load stability up to 10,000pF, shutdown mode (<200µA IS), adjustable supply current via external resistor, ±5V to ±15V dual-supply operation, and 7-lead DD package thermal performance (θJA = 30°C/W with 2500 mm² copper).
Technical Context
The LT1206CR#TRPBF employs a proprietary complementary bipolar architecture with current-feedback topology, enabling wide bandwidth independent of closed-loop gain while maintaining high slew rate and low distortion. Its transresistance input stage provides high input impedance (10MΩ) and low input bias current asymmetry.
Stability with large capacitive loads is achieved via optional COMP pin compensation (0.01µF between OUT and COMP), and shutdown control is implemented through a supply-referenced S/D pin that adjusts quiescent current from 30mA down to <200µA - supporting dynamic power management in video signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-Signal Bandwidth | 60MHz at AV = 2, RL = 100Ω - supports full HD baseband video signal integrity without gain-dependent bandwidth roll-off. |
| Slew Rate | 900V/µs at AV = 2, RL = 50Ω - enables clean 1080p/60Hz RGB signal reproduction with minimal edge distortion. |
| Differential Gain / Phase | 0.02% / 0.17° at NTSC video level (2V), RL = 30Ω - meets broadcast-grade color fidelity requirements for analog video systems. |
| Output Drive Current | 250mA minimum - drives multiple 75Ω coaxial cables simultaneously without gain compression or thermal derating. |
| Supply Range | ±5V to ±15V - accommodates legacy industrial video gear and modern low-voltage designs via adjustable quiescent current. |
| Shutdown Current | <200µA - reduces system standby power in portable test instruments and modular video routers. |
| Capacitive Load Stability | Stable with CL = 10,000pF - eliminates need for external isolation resistors when driving long PCB traces or backplane interconnects. |
Pinout & Package
The LT1206CR#TRPBF is housed in a 7-lead plastic DD (R) package with exposed thermal tab connected to V+; θJA = 30°C/W with 2500 mm² copper area. Pin 1 is V+, Pin 2 is OUT, Pin 3 is V–, Pin 4 is COMP, Pin 5 is V+, Pin 6 is S/D, Pin 7 is –IN, and +IN is internally tied to Pin 5 (V+) - confirming noninverting configuration by default.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ (Pins 1, 5) | Positive Supply Input | Dual connection improves current delivery and thermal path; tab is electrically tied to V+ for enhanced heatsinking. |
| OUT (Pin 2) | Amplifier Output | Capable of sourcing/sinking ≥250mA; requires direct routing to load to preserve bandwidth and minimize parasitic inductance. |
| V– (Pin 3) | Negative Supply Input | Reference for internal biasing; must be decoupled locally with low-ESR capacitor near package. |
| COMP (Pin 4) | Compensation Node | Optional 0.01µF capacitor to OUT flattens response with capacitive loads; leave open for purely resistive termination. |
| S/D (Pin 6) | Shutdown Control | Supply-referenced input: grounded for normal operation; pulled to V+ to enter shutdown (<200µA IS). |
| –IN (Pin 7) | Inverting Input | Current-feedback node requiring precise resistive feedback (e.g., 560Ω) to maintain stability and bandwidth. |
| +IN (Internal) | Noninverting Input | Internally connected to Pin 5 (V+); device operates as unity-gain buffer unless external feedback network is added. |
Key Features
| Feature | Design Value |
|---|---|
| Current-feedback architecture | Enables constant 60MHz bandwidth across gains - critical for multi-channel RGB amplifiers where gain varies per channel. |
| 10,000pF capacitive load tolerance | Eliminates series isolation resistors in video line drivers, preserving DC coupling and reducing component count. |
| Adjustable supply current (5–30mA) | Single external resistor on S/D pin scales power vs. bandwidth trade-off - e.g., 121kΩ sets IS ≈ 5mA for low-power test fixtures. |
| 0.02% differential gain | Ensures accurate color saturation in NTSC/PAL video without post-correction circuitry or calibration. |
| Thermal shutdown protection | Prevents latch-up during overload or poor heatsinking; cycles slowly (10ms–seconds) to avoid system interruption. |
Applications
| RGB Video Distribution | Test Equipment Signal Buffer |

Equivalent & Alternatives
The following parts are listed as comparable options for similar current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1226CS8#TRPBF | Higher 100MHz bandwidth but lower 140mA output drive; no shutdown pin; SO-8 package only. | Better suited for high-speed ADC buffering than multi-cable video distribution. | Select when bandwidth >60MHz is mandatory and load current ≤140mA. |
| THS3091DGNR | 2100V/µs slew rate, 220MHz bandwidth, but higher 12.5mA quiescent current and no COMP pin for capacitive loads. | Optimized for pulse amplification in medical imaging, not broadcast video fidelity. | Select for ultrafast transient response where differential gain/phase specs are secondary. |
Compared with LT1226CS8#TRPBF and THS3091DGNR, the LT1206CR#TRPBF uniquely balances high output current (250mA), video-optimized distortion performance (0.02%/0.17°), and integrated capacitive-load compensation - making it irreplaceable in cost-sensitive, thermally constrained RGB distribution designs.

FAQ
What is the maximum capacitive load the LT1206CR#TRPBF can drive stably?
The LT1206CR#TRPBF is specified stable with up to 10,000pF capacitive load when the COMP pin is used with a 0.01µF capacitor to OUT. Without COMP compensation, stability degrades above ~1000pF. This capability eliminates external isolation resistors in video line drivers and simplifies PCB layout for high-current analog signal routing.
How does the shutdown feature work on the LT1206CR#TRPBF?
The LT1206CR#TRPBF shutdown pin (S/D) is supply-referenced: grounding it enables normal operation (IS ≈ 30mA), while pulling it to V+ places the device in low-power mode (IS < 200µA). The output enters high-impedance state with ~40pF capacitance. This allows dynamic power gating in battery-operated test gear without external MOSFET switches.
Can the LT1206CR#TRPBF be used in single-supply configurations?
Yes - the LT1206CR#TRPBF operates from split supplies (±5V to ±15V) or single supplies (10V to 30V total), provided input common-mode and output swing remain within specified limits. For single-supply use, bias the +IN node at mid-rail using resistive divider and AC-couple inputs/outputs to maintain DC operating point.
What is the thermal resistance of the LT1206CR#TRPBF in its 7-lead DD package?
The LT1206CR#TRPBF in R-package has θJA = 30°C/W when mounted on a 2500 mm² copper area (1 oz), per Linear's characterization data. With smaller copper (e.g., 125 mm²), θJA rises to 35°C/W. The exposed V+-tied tab enables direct thermal coupling to ground planes, making it superior to SO-8 alternatives for high-power video applications.
Does the LT1206CR#TRPBF require external compensation for resistive loads?
No - the COMP pin should be left open (unconnected) for purely resistive loads like 75Ω video terminations. Connecting the 0.01µF capacitor between OUT and COMP reduces bandwidth (e.g., 55MHz → 35MHz into 30Ω) and introduces unnecessary phase shift. Compensation is strictly for capacitive-load stabilization, not general-purpose use.
