Product details
Overview
LT6210IS6#TRPBF 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 700V/µs slew rate, ±75mA output drive, and maintains video-grade performance (0.20% differential gain, 0.10° differential phase) into 150Ω loads. It is used in high-speed cable drivers and portable video signal conditioning.
For engineers reviewing the LT6210IS6#TRPBF datasheet, LT6210IS6#TRPBF pinout, LT6210IS6#TRPBF application, or LT6210IS6#TRPBF equivalent, key selection criteria include programmable quiescent current vs. bandwidth trade-off, ISET pin biasing method, rail-to-rail output swing under varying load conditions, and thermal performance in the 6-lead TSOT-23 package at –40°C to 85°C.
Technical Context
The LT6210IS6#TRPBF employs a current-feedback architecture with an ISET pin that sets quiescent current via external resistor or current source - enabling precise optimization of bandwidth, slew rate, and distortion without changing gain-setting resistors. Its transimpedance stage provides high open-loop gain stability across supply voltages from ±1.5V to ±6V or 3V to 12V single supply.
It features a low-distortion rail-to-rail output stage capable of driving ±75mA into 150Ω while maintaining <0.1% settling in 20ns for 2V steps. Input common-mode range extends to within 1.2V of rails, and C-Load™ capability allows stable operation with capacitive loads up to 10nF when series resistance is applied.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current Range | 300µA to 6mA per amplifier - enables dynamic power/bandwidth scaling; 300µA yields 10MHz BW, 6mA yields 200MHz BW. |
| Slew Rate | 700V/µs at 6mA - supports fast transient response for video and communication signals without slewing distortion. |
| Output Drive | ±75mA minimum into 150Ω - sufficient for driving coaxial cables and multiple downstream loads without buffering. |
| Rail-to-Rail Output Swing | 0.05V to 2.85V on 3V supply; ±4.8V on ±5V supply - maximizes dynamic range in low-voltage and dual-supply systems. |
| Differential Gain/Phase | 0.20% / 0.10° into 150Ω - meets broadcast video fidelity requirements for SD/HD analog video paths. |
| Input Noise Density | 6.5nV/√Hz at 6mA - low enough for high-fidelity signal amplification without significant SNR degradation. |
| Bandwidth (AV = 1) | 200MHz at IS = 6mA - supports wideband applications including RF IF stages and high-speed data acquisition front-ends. |
Pinout & Package
LT6210IS6#TRPBF is housed in a 6-lead TSOT-23 package (1mm height), specified for –40°C to 85°C operation. The package exposes no thermal pad; thermal resistance θJA = 230°C/W on minimal copper, dropping to 160°C/W with 20mm² copper attached to Pin 2 (V–).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT | Amplifier output | Drives load directly; rail-to-rail swing supports full utilization of supply voltage headroom. |
| V– | Negative supply rail | Reference for internal bias; also serves as thermal path when connected to PCB copper. |
| +IN | Noninverting input | High-impedance node (≥0.5MΩ); accepts input signals up to V+ – 1.2V and V– + 1.2V. |
| ISET | Quiescent current control | Connect external resistor to V– (or ground) to set supply current; 20kΩ → 6mA, 56kΩ → 3mA, 1MΩ → 300µA. |
| –IN | Inverting input | Current-input node of CFB topology; feedback resistor connects here to set closed-loop gain and bandwidth. |
| V+ | Positive supply rail | Accepts 3V to 12V single supply or up to ±6V dual supply; PSRR >60dB over 0.001–10MHz. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable bandwidth | 10MHz to 200MHz via ISET resistor - eliminates need for multiple op-amp variants in scalable designs. |
| C-Load™ capacitive drive | Stable with ≥10nF load when series resistor ≥15Ω - simplifies termination for long traces or cables without external isolation. |
| Fast settling time | 20ns to 0.1% for 2V step - enables accurate pulse amplification in test equipment and data converters. |
| Low distortion at 1MHz | –70dBc HD2 / –75dBc HD3 at 2VP-P - preserves signal integrity in composite video and baseband communication paths. |

FAQ
What is the function of the ISET pin on the LT6210IS6#TRPBF?
The ISET pin on the LT6210IS6#TRPBF sets the amplifier's quiescent supply current via an external resistor to V– (or ground). A 20kΩ resistor yields 6mA, 56kΩ yields 3mA, and 1MΩ yields 300µA. This direct current control enables dynamic optimization of bandwidth, slew rate, and distortion without altering gain configuration - a core feature distinguishing the LT6210IS6#TRPBF from fixed-current op-amps.
Can the LT6210IS6#TRPBF drive a 75Ω coaxial cable directly?
Yes, the LT6210IS6#TRPBF can drive a 75Ω coaxial cable directly when configured for 6mA supply current, delivering 200MHz bandwidth and 0.20% differential gain into 150Ω (standard video load). For 75Ω, use matched 75Ω series termination at the output and ensure feedback resistor values (e.g., RF = RG = 887Ω) maintain stability and gain accuracy - verified in the LT6210IS6#TRPBF typical application circuits.
What is the maximum capacitive load the LT6210IS6#TRPBF can drive stably?
The LT6210IS6#TRPBF can drive up to 10nF capacitively when a series resistor ≥15Ω is placed between the output and load - a capability enabled by its C-Load™ architecture. Without series resistance, stability degrades beyond ~100pF. The exact limit depends on supply current: at 6mA, feedback resistor value (e.g., 887Ω), and load impedance - refer to Figure 30 in the LT6210IS6#TRPBF datasheet for capacitive load vs. feedback resistance curves.
How does the LT6210IS6#TRPBF perform on a 3V single supply?
On a 3V single supply, the LT6210IS6#TRPBF delivers rail-to-rail output swing from 0.05V to 2.85V into 150Ω, supports 70MHz bandwidth at 3mA, and maintains –70dBc HD2 at 1MHz. Its input common-mode range spans 0.8V to 2.2V, and PSRR exceeds 60dB - making it suitable for battery-powered video and sensor interfaces where headroom and power efficiency are critical.
Is the LT6210IS6#TRPBF pin-compatible with other TSOT-23 op-amps?
No, the LT6210IS6#TRPBF has a unique 6-pin TSOT-23 pinout (OUT, V–, +IN, ISET, –IN, V+) not shared by standard voltage-feedback op-amps like the LT1782 or ADA4891-1. Substituting requires PCB layout changes due to ISET pin placement and CFB-specific feedback topology - the LT6210IS6#TRPBF must be designed-in from the outset for its programmable current and current-feedback advantages.
