Product details
Overview
LT6211CMS#PBF from Analog Devices (formerly Linear Technology) is a dual current feedback amplifier with programmable supply current per channel (300µA to 6mA), rail-to-rail output, 700V/µs slew rate, and 200MHz bandwidth at 6mA. It operates on ±1.5V to ±6V or 3V–12V supplies and delivers ±75mA minimum output drive-ideal for high-speed video buffering and cable driver applications in compact MSOP-10 form factor.
For engineers reviewing the LT6211CMS#PBF datasheet, LT6211CMS#PBF pinout, LT6211CMS#PBF application, or LT6211CMS#PBF equivalent, key selection criteria include programmable bandwidth vs. quiescent current trade-off, differential gain/phase performance into 150Ω, C-Load™ capacitive-load drive capability, and dual-channel isolation in 10-lead MSOP package.
Technical Context
The LT6211CMS#PBF implements a current feedback architecture with two independent ISET pins enabling per-channel quiescent current programming via external resistors. Bandwidth scales directly with supply current: 10MHz at 300µA/channel, 100MHz at 3mA, and 200MHz at 6mA under ±5V/150Ω conditions.
Its rail-to-rail output stage supports 0.05V to 2.85V swing on 3V single supply and up to ±4.8V on ±5V, with fast settling (20ns to 0.1%), low distortion (–70dB HD2, –75dB HD3 at 1MHz), and excellent channel separation (>100dB at 1MHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current Range | 300µA to 6mA per amplifier - enables dynamic power/bandwidth optimization without changing layout |
| Small-Signal Bandwidth | 200MHz at 6mA (±5V, AV=1, RL=150Ω) - supports high-definition video and broadband signal conditioning |
| Slew Rate | 700V/µs - ensures faithful reproduction of fast transients in pulse and video signals |
| Output Drive | ±75mA minimum - drives heavy loads including 75Ω/150Ω video lines and capacitive cables |
| Differential Gain/Phase | 0.20% / 0.10° into 150Ω - meets broadcast-grade video fidelity requirements |
| Rail-to-Rail Output | 0.05V to 2.85V on 3V supply - maximizes dynamic range in low-voltage systems |
| Input Noise Density | 6.5nV/√Hz at 6mA - preserves SNR in precision analog front-ends |
Pinout & Package
LT6211CMS#PBF is housed in a 10-lead plastic MSOP package (3mm × 3mm, 0.8mm height) with exposed pad connected to V– for thermal management. Pin 1 is OUT A; pin 10 is V–. The package supports standard reflow and offers θJA = 120°C/W on 2oz copper FR-4 board with 100mm² copper attached to Pin 5 (ISET A).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT A | Amplifier A output | Drives external load; rail-to-rail capable; requires local 0.1µF bypass |
| V– | Negative supply rail | Reference for both amplifiers; exposed pad must be soldered to PCB ground plane |
| +IN A | Noninverting input A | High-impedance node (≥0.5MΩ); protected by ESD diodes |
| –IN A | Inverting input A | Current-feedback node; sensitive to parasitic capacitance; keep trace short |
| ISET A | Quiescent current control A | Connect resistor to V– to set IS; open-circuit not allowed; sets bandwidth/slew rate |
| OUT B | Amplifier B output | Independent output; >100dB channel separation at 1MHz prevents crosstalk |
| –IN B | Inverting input B | Electrically isolated from Channel A; same layout rules apply |
| +IN B | Noninverting input B | Independent high-Z input; common-mode range extends to within 1.2V of rails |
| ISET B | Quiescent current control B | Independent of ISET A; allows asymmetric channel configuration |
| V+ | Positive supply rail | Accepts 3V–12V single or ±1.5V–±6V dual; bypass with 0.1µF ceramic + 4.7µF tantalum |
Key Features
| Feature | Design Value |
|---|---|
| Programmable bandwidth | 10MHz to 200MHz per channel via ISET resistor - eliminates need for multiple op-amp SKUs |
| C-Load™ capacitive-drive capability | Stable with unlimited capacitive loads - removes need for series isolation resistors in LCD/camera interfaces |
| Video-optimized distortion performance | –70dB HD2 / –75dB HD3 at 1MHz - meets NTSC/PAL broadcast linearity specs without post-correction |
| Wide supply flexibility | Operates from 3V single supply or ±1.5V dual - supports battery-powered and industrial rail systems |
| Low-power high-speed operation | 300µA/channel delivers 10MHz BW - enables always-on sensor signal conditioning in portable devices |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual current feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT6211CDD#PBF | Same electrical specs but in 3mm × 3mm DFN-10 package with exposed pad tied to V–; θJA = 43°C/W vs. 120°C/W for MSOP | Better thermal performance required in high-density, high-power applications; no leaded option for wave-soldering | Select when PCB space is constrained and thermal dissipation >150mW per channel is expected |
| ADA4891-2ARZ | Voltage-feedback architecture; fixed 220MHz GBW; 175V/µs slew rate; 2.7–12V supply; no ISET pin or programmable current | Lacks bandwidth/power trade-off flexibility; higher quiescent current (6.5mA typical); lower output drive (±65mA) | Choose only if fixed high-speed, low-distortion performance suffices and programmability is unnecessary |
Compared with LT6211CDD#PBF, LT6211CMS#PBF trades thermal efficiency for leaded manufacturability and easier prototyping; versus ADA4891-2ARZ, it provides unique current-programmable bandwidth and superior output drive, critical for video and cable applications where dynamic power scaling matters.

FAQ
What is the maximum supply voltage rating for LT6211CMS#PBF?
The LT6211CMS#PBF has an absolute maximum total supply voltage (V+ to V–) of 13.2V. It operates across a wide range: 3V to 12V single supply or ±1.5V to ±6V dual supplies. Exceeding 13.2V risks permanent damage, and operation above ±6V or 12V is not characterized or guaranteed.
Can LT6211CMS#PBF drive a 75Ω video load with broadcast-quality linearity?
Yes. The LT6211CMS#PBF delivers 0.20% differential gain and 0.10° differential phase into a 150Ω load (equivalent to two 75Ω loads in parallel), meeting NTSC/PAL broadcast standards. Its rail-to-rail output and 700V/µs slew rate maintain fidelity for 1080i/60 video signals without external correction circuitry.
How does the ISET pin function on LT6211CMS#PBF?
The ISET pin on LT6211CMS#PBF sets quiescent current per channel using an external resistor to V–. For example, 20kΩ yields ~6mA, 56kΩ yields ~3mA, and 1MΩ yields ~300µA. Both ISET A and ISET B must be terminated - floating pins cause undefined bias and instability. The ISET pin is not a shutdown control.
Is LT6211CMS#PBF stable driving large capacitive loads?
Yes. The LT6211CMS#PBF features C-Load™ technology, meaning it remains stable with unlimited capacitive loads without requiring external series isolation resistors. This eliminates signal degradation and simplifies layout in LCD interface, camera module, and long-cable applications where capacitance exceeds 1000pF.
What is the thermal resistance (θJA) of LT6211CMS#PBF in MSOP-10 package?
The LT6211CMS#PBF in MSOP-10 has a specified θJA of 120°C/W, measured on a 2500mm² 3/32″ FR-4 board with 2oz copper on both sides and 100mm² copper attached to Pin 5 (ISET A). Performance improves with additional copper area or multi-layer boards - never leave the exposed pad unconnected.
