Product details
Overview
LT6205HS5#TRPBF from Analog Devices (formerly Linear Technology) is a single, high-speed, rail-to-rail output voltage-feedback operational amplifier optimized for 100MHz video signal processing in automotive and industrial environments. It delivers 450V/μs slew rate, 50mA output drive, and operates from 2.7V to 12.6V supply with input common-mode range including ground - enabling robust DC-coupled video amplification in compact SOT-23 layouts.
For engineers reviewing the LT6205HS5#TRPBF datasheet, LT6205HS5#TRPBF pinout, LT6205HS5#TRPBF application, or LT6205HS5#TRPBF equivalent, key selection criteria include its –40°C to 125°C automotive-grade temperature rating, 3.5mV typical input offset voltage, rail-to-rail output swing within 60mV of rails at 5mA load, 90dB channel separation at 10MHz, and compatibility with 75Ω coaxial cable driver topologies requiring low distortion and fast settling.
Technical Context
The LT6205HS5#TRPBF employs a proprietary complementary drive generator output stage that enables true rail-to-rail swing while maintaining high slew rate across its full operating voltage range. Its input stage uses back-to-back diodes (±1.4V differential limit) and series current-limiting resistors for robust overvoltage protection without phase reversal.
It is internally compensated for unity-gain stability and optimized for driving capacitive loads up to 20pF directly; larger loads require external series isolation resistors (10–50Ω) between output and load to maintain 3% settling in ≤25ns. Gain-bandwidth remains stable across temperature and supply variations, with 50MHz minimum GBW guaranteed over –40°C to 125°C.
Key Specifications

| Supply Range | 2.7V to 12.6V; operates from single 3.3V or 5V rails, or split ±5V supplies |
| Channel Separation | 90dB at 10MHz; critical for dual-channel RGB or Y/C separation in multi-amplifier systems |

Use Value: 90dB channel separation at 10MHz eliminates ghosting between split outputs; 3.5mV max VOS ensures consistent black-level alignment across all outputs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6629MA/NOPB | Higher 1.5GHz GBW but 12mA quiescent current; no guaranteed 125°C operation | Better for >100MHz RF IF stages; unsuitable for automotive under-hood deployment | Select LMH6629MA/NOPB only when bandwidth >500MHz is required and temperature range ≤85°C suffices |
| ADA4891-1ARJZ-R7 | Lower 225MHz GBW, 175V/μs slew, 1.2mA IS; specified only to 105°C | Lower power alternative for non-automotive portable video; lacks 125°C qualification and 50mA drive | Choose ADA4891-1ARJZ-R7 for battery-powered consumer displays where thermal margin is limited and 125°C is unnecessary |
Compared with LMH6629MA/NOPB and ADA4891-1ARJZ-R7, the LT6205HS5#TRPBF uniquely balances 100MHz bandwidth, 450V/μs slew, 50mA drive, and full –40°C to 125°C automotive qualification in a 5-pin SOT-23 - making it the only drop-in solution for space-constrained, thermally harsh video signal conditioning.

FAQ
What is the maximum guaranteed gain-bandwidth product for LT6205HS5#TRPBF over its full temperature range?
The LT6205HS5#TRPBF guarantees a minimum gain-bandwidth product of 50MHz across its full –40°C to 125°C operating temperature range, as specified in the Electrical Characteristics table for the LT6205H grade. This is lower than the 100MHz typical value measured at 25°C but ensures predictable bandwidth performance in automotive under-hood environments where thermal derating applies.
Can LT6205HS5#TRPBF drive a 75Ω coaxial cable directly without external components?
No - the LT6205HS5#TRPBF cannot drive a 75Ω coaxial cable directly. It requires a 75Ω series resistor at the output to form a proper source termination matching the cable characteristic impedance. This creates a 2:1 voltage divider, so the amplifier must deliver 2VP-P to achieve 1VP-P at the load. The LT6205HS5#TRPBF's 50mA output drive and rail-to-rail swing make it fully capable of this requirement on 3.3V or 5V supplies.
Does LT6205HS5#TRPBF support true single-supply operation with input referenced to ground?
Yes - the LT6205HS5#TRPBF supports true single-supply operation with input common-mode voltage ranging from V– (ground) to V+ – 2V. Its input stage includes ground-sensing capability and does not require level-shifting circuitry for DC-coupled video signals with 0V black level references, unlike many older op amps that demand input bias above ground.
What is the purpose of the back-to-back diodes on the inputs of LT6205HS5#TRPBF?
The back-to-back diodes on the +IN and –IN pins of the LT6205HS5#TRPBF limit differential input voltage to ±1.4V, protecting the internal transistors from overvoltage damage. When used with the integrated 150Ω input current-limiting resistors (RIN), they allow safe operation even if inputs are driven beyond the supply rails - provided transient current stays below 25mA, as confirmed in Absolute Maximum Ratings and Applications Information.
Is LT6205HS5#TRPBF pin-compatible with other members of the LT6205/LT6206/LT6207 family?
Yes - the LT6205HS5#TRPBF shares identical 5-lead TSOT-23 pinout with all LT6205 variants (C/I/H grades), including LT6205CS5#TRPBF and LT6205IS5#TRPBF. This allows direct substitution in existing designs when upgrading to the extended temperature range, provided PCB layout and thermal management accommodate the higher 125°C junction limit and associated power dissipation behavior.
