Product details
Overview
LT6210IS6#TRMPBF from Analog Devices (formerly Linear Technology) is a single-channel, current-feedback operational amplifier with externally programmable supply current (300µA to 6mA), rail-to-rail output, and bandwidth scalable from 10MHz to 200MHz. It delivers ±75mA output drive, 700V/µs slew rate, and supports ±1.5V to ±6V or 3V–12V supplies. It is used in high-speed video buffering and cable driver applications requiring low distortion and capacitive-load stability.
For engineers reviewing the LT6210IS6#TRMPBF datasheet, LT6210IS6#TRMPBF pinout, LT6210IS6#TRMPBF application, or LT6210IS6#TRMPBF equivalent, key selection criteria include programmable quiescent current vs. bandwidth trade-off, C-Load™ capacitive-drive capability, differential gain/phase performance into 150Ω, and TSOT-23 thermal behavior under varying ISET configurations.
Technical Context
The LT6210IS6#TRMPBF employs a current-feedback architecture with an ISET pin that controls bias current via external resistor or current source, enabling dynamic optimization of bandwidth, slew rate, and harmonic distortion. Its transimpedance gain stage drives a low-impedance rail-to-rail output stage capable of ±75mA into 150Ω loads.
It operates across wide supply ranges (±1.5V to ±6V or 3V–12V) while maintaining stable quiescent current independent of supply voltage. Input protection includes back-to-back diodes and ESD structures, with common-mode input range extending to within 1.2V of rails on ±5V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current Range | 300µA to 6mA per amplifier - enables power/bandwidth tuning without changing layout |
| Small-Signal Bandwidth | 10MHz at 300µA; 200MHz at 6mA - directly scalable with ISET resistor value |
| Slew Rate | 120V/µs (300µA) to 700V/µs (6mA) - supports fast transient response in video and line-driver stages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT6200CS6#TRMPBF | Fixed 20mA supply current; 500MHz bandwidth; no ISET pin; higher power consumption | Better for fixed-high-speed applications where programmability is unnecessary | Select when maximum bandwidth is prioritized over power scalability |
| ADA4891-1ARJZ-R7 | Voltage-feedback topology; 220MHz GBW; 175V/µs slew; no programmable current; lower noise (4.5nV/√Hz) | Preferred for precision DC-coupled gain stages with tighter offset specs | Select when low input offset (0.5mV max) and voltage-feedback stability are critical |

FAQ
What is the operating temperature range for LT6210IS6#TRMPBF?
The LT6210IS6#TRMPBF is specified for operation from –40°C to +85°C. This industrial temperature grade is confirmed in the order information table, where "I" denotes the –40°C to 85°C range, and the S6 package marking "LTA3" corresponds to this grade. The device undergoes full performance testing across this range.
How does the ISET pin on LT6210IS6#TRMPBF set supply current?
The ISET pin on LT6210IS6#TRMPBF accepts an external resistor to V– (or a current sink) to program supply current from 300µA to 6mA. For example, a 20kΩ resistor yields ~6mA on ±5V supplies. The relationship is monotonic and documented in the Typical AC Performance table; no external bias circuitry is needed beyond the resistor.
Can LT6210IS6#TRMPBF drive a 75Ω coaxial cable directly?
Yes, LT6210IS6#TRMPBF can drive a 75Ω coaxial cable directly. Its ±75mA output current and 0.20%/0.10° differential gain/phase performance into 150Ω (effectively two 75Ω terminations) are validated in the datasheet. Application circuits show 75Ω series termination at the output with no isolation resistor required due to C-Load™ stability.
What is the maximum capacitive load LT6210IS6#TRMPBF can drive without compensation?
LT6210IS6#TRMPBF can drive unlimited capacitive loads without external compensation, thanks to its C-Load™ architecture. The datasheet confirms stability with >10,000pF loads when using appropriate feedback resistors (e.g., 887Ω at 6mA). This eliminates series isolation resistors typically needed with conventional op amps.
Does LT6210IS6#TRMPBF support single-supply operation?
Yes, LT6210IS6#TRMPBF supports single-supply operation from 3V to 12V. At 3V, it delivers rail-to-rail output swing from 0.05V to 2.85V into 150Ω, and the ISET pin is biased to V– (ground) via resistor. Input common-mode range extends to within 1.2V of rails, enabling use with simple level-shifting networks.
