Product details
Overview
LT6205IS5#TRMPBF from Analog Devices (formerly Linear Technology) is a single, rail-to-rail output, voltage-feedback operational amplifier optimized for high-speed video signal conditioning. It delivers 100MHz gain-bandwidth product, 450V/μs slew rate, and ±50mA output drive while operating from 2.7V to 12.6V supplies. Its input common-mode range includes ground and output swings within 60mV of rails - making it ideal for single-supply 3.3V RGB amplifiers and coaxial cable drivers in automotive displays.
For engineers reviewing the LT6205IS5#TRMPBF datasheet, LT6205IS5#TRMPBF pinout, LT6205IS5#TRMPBF application, or LT6205IS5#TRMPBF equivalent, key selection criteria include guaranteed –40°C to 85°C industrial temperature operation, SOT-23-5 package footprint compatibility, 1mV typical input offset voltage, and verified 90dB channel separation at 10MHz for multi-channel video systems.
Technical Context
The LT6205IS5#TRMPBF uses a complementary bipolar input stage with back-to-back diode clamps enabling robust overvoltage tolerance without phase reversal. Its slew rate is determined by internal current through degeneration resistors and scales inversely with closed-loop gain - delivering peak 450V/μs at AV = 2 under 5V supply.
Stability is maintained up to 20pF capacitive load in unity-gain configuration; larger loads require series output isolation (10–50Ω). The device features reverse-biased ESD diodes on all pins, supporting transient currents ≤25mA beyond supply rails without damage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 100MHz - enables stable closed-loop operation up to 10MHz with AV ≥ 10, suitable for HD video baseband bandwidth. |
| Slew Rate | 450V/μs - supports full-swing 2V step response in <25ns, critical for composite video transient fidelity. |
| Output Drive Current | ±50mA - drives 75Ω coaxial cables with 2VP-P into 150Ω effective load (back-terminated), meeting broadcast video line driver requirements. |
| Input Offset Voltage | 1mV (typ) - ensures DC accuracy in RGB amplifiers where black-level shift must stay <10mV across temperature. |
| Supply Range | 2.7V to 12.6V - operates from single 3.3V or 5V rails, eliminating need for dual supplies in portable display interfaces. |
| Rail-to-Rail Output | Swings within 60mV of V+ and V– - preserves >95% dynamic range in 3.3V systems, minimizing headroom loss vs legacy op-amps. |
| Channel Separation | 90dB at 10MHz - prevents crosstalk between adjacent video channels (e.g., Y/C or R/G/B) in multi-amplifier PCB layouts. |
Pinout & Package
The LT6205IS5#TRMPBF is housed in a 5-lead TSOT-23 (ThinSOT™) package, 1mm profile, with industry-standard op-amp pinout compatible with space-constrained video routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V– (Pin 2) | Negative supply rail | Reference for single-supply operation; accepts 0V (ground) when using 3.3V or 5V rails. |
| +IN (Pin 3) | Non-inverting input | DC-coupled compatible; common-mode range includes ground, enabling direct connection to video sync tips. |
| –IN (Pin 4) | Inverting input | Accepts feedback network; requires ≤1kΩ resistors to avoid stability degradation from input capacitance pole. |
| OUT (Pin 1) | Amplifier output | Capable of sourcing/sinking 50mA; requires 10–50Ω series resistor when driving >20pF capacitive loads to suppress ringing. |
| V+ (Pin 5) | Positive supply rail | Bypassed with 0.01–0.1μF ceramic capacitor ≤0.25″ away to maintain 100MHz stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Enables full utilization of 3.3V supply in RGB amplifiers without level-shifting circuitry. |
| Input range includes ground | Permits direct coupling of NTSC/PAL sync tips and black-level references without AC coupling or bias networks. |
| High channel separation (90dB @ 10MHz) | Reduces inter-channel interference in multi-amplifier video splitters, preserving color fidelity in component systems. |
| Robust overvoltage tolerance | Withstands ±1.4V differential input overdrive and transient excursions beyond rails ≤25mA, simplifying front-end protection design. |
| Low 20mW power per amplifier (5V) | Supports thermally constrained automotive display modules and portable HDMI transmitter boards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6702MF/NOPB | Higher 1.7GHz GBW but 12mA quiescent current; no rail-to-rail output (VOH = V+ – 1.2V). | Requires dual supplies for full video swing; better suited for RF IF stages than baseband video. | Choose LMH6702MF/NOPB only if >500MHz small-signal bandwidth is required and rail-to-rail output is unnecessary. |
| ADA4817-1ARMZ | Lower 1.05GHz GBW, 2.5nV/√Hz noise, but 105mA output drive and –40°C to 125°C grade available. | Superior noise performance for low-light imaging; higher drive supports active termination in long-haul video links. | Select ADA4817-1ARMZ when sub-3nV/√Hz noise or extended temperature range beyond 85°C is mandatory. |
Compared with LMH6702MF/NOPB and ADA4817-1ARMZ, the LT6205IS5#TRMPBF offers optimal balance of rail-to-rail output, 100MHz bandwidth, and 3.3V compatibility - making it the preferred choice for cost-sensitive, space-constrained RGB and coaxial video interfaces where full supply utilization is essential.

FAQ
What is the maximum capacitive load the LT6205IS5#TRMPBF can drive without external compensation?
The LT6205IS5#TRMPBF is stable driving up to 20pF in unity-gain configuration. For loads exceeding 20pF - such as long PCB traces or connector parasitics - a 10Ω to 50Ω series resistor must be placed directly at the LT6205IS5#TRMPBF output pin before the capacitive load to ensure stability and prevent overshoot. This isolation technique is validated in the datasheet's Typical Performance Characteristics (Figure G27–G28).
Does the LT6205IS5#TRMPBF support true single-supply operation with input referenced to ground?
Yes. The LT6205IS5#TRMPBF features an input common-mode range that includes ground (0V) and extends to V+ – 2V, allowing direct DC coupling of video sync tips and black-level references without level-shifting circuitry. This is confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables, where input voltage range is specified as 0V to V+ – 2V for single-supply conditions.
What is the guaranteed operating temperature range for the LT6205IS5#TRMPBF?
The LT6205IS5#TRMPBF is specified and guaranteed over the industrial temperature range of –40°C to +85°C. This is explicitly stated in the Order Information table under "LT6205IS5#PBF / LT6205IS5#TRPBF" and reinforced in Note 4 of the Electrical Characteristics section, which confirms full-range testing and qualification for the "I" grade.
Can the LT6205IS5#TRMPBF replace the LT6205CS5#TRPBF in existing designs?
Yes - the LT6205IS5#TRMPBF is pin-compatible and functionally identical to the LT6205CS5#TRPBF except for its extended –40°C to 85°C temperature rating (vs. 0°C to 70°C for the "C" grade). Electrical parameters including GBW, slew rate, and offset voltage are identical across both grades at 25°C, and the "I" grade maintains full specification compliance across its wider range.
What layout practices are critical for maintaining 100MHz stability with the LT6205IS5#TRMPBF?
Essential layout practices include: (1) placing a 0.01–0.1μF ceramic bypass capacitor ≤0.25″ from the V+ pin; (2) using a solid ground plane beneath the device; (3) keeping feedback and gain-setting resistors within a 0.5″ × 0.5″ zone near the package; and (4) limiting inverting-input node capacitance by using ≤1kΩ resistors - all mandated in the Applications Information section to prevent peaking or oscillation at high frequencies.
