Product details
Overview
LT1210IR#TRPBF from Analog Devices is a current feedback amplifier optimized for high-output-current, wide-bandwidth applications such as cable drivers and video amplifiers. It delivers 1.1A minimum output drive, 35MHz bandwidth at AV = 2 with 10Ω load, 900V/µs slew rate, ±5V to ±15V supply operation, and operates across –40°C to 85°C.
For engineers reviewing the LT1210IR#TRPBF datasheet, LT1210IR#TRPBF pinout, LT1210IR#TRPBF application, or LT1210IR#TRPBF equivalent, key selection criteria include capacitive-load stability (up to 10,000pF), shutdown mode (<200µA supply current), adjustable quiescent current via external resistor, and compatibility with ±5V SO-16 or ±15V DD/TO-220 packages.
Technical Context
The LT1210IR#TRPBF uses a current feedback architecture with separate input and output stages, enabling high slew rate and large-signal bandwidth independent of closed-loop gain configuration. Its transresistance stage provides stable gain control through feedback resistor selection rather than internal compensation.
It features an optional COMP pin for capacitive-load compensation, a SHUTDOWN pin referenced to V+ for bias current control, and thermal shutdown protection triggered above 150°C junction temperature. The device maintains stability with 10,000pF loads when COMP is connected, and supports adjustable supply current from 7.5mA to 50mA using external RSD.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 35MHz at AV = 2, RL = 10Ω - enables high-fidelity video signal amplification up to 1080p line rates |
| Slew Rate | 900V/µs at AV = 2, RL = 10Ω - supports fast transient response in ADSL line drivers and test equipment |
| Output Drive | 1.1A min into RL = 1Ω - drives low-impedance coaxial cables and twisted-pair lines without external buffers |
| Supply Range | ±5V to ±15V - accommodates both low-voltage portable systems and high-power industrial signal chains |
| Capacitive Load Stability | Stable with CL = 10,000pF when COMP pin used - eliminates need for external isolation resistors in LCD panel or DAC output buffering |
| Shutdown Current | <200µA - reduces system power by >99% during idle periods in battery-powered instrumentation |
| Input Impedance | 10MΩ - minimizes loading on high-impedance sensor or DAC outputs in precision signal paths |
Pinout & Package
The LT1210IR#TRPBF is packaged in a 7-lead Plastic DD (R package), with exposed tab electrically connected to V+. Thermal resistance θJA is 27°C/W with 1000 mm² copper area on top side of PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT | Amplifier Output | High-current output node capable of sourcing/sinking 1.1A; requires low-inductance layout for RF stability |
| V– | Negative Supply Rail | Connects to negative supply; also serves as reference for inverting input stage and thermal shutdown circuitry |
| COMP | Compensation Terminal | Optional connection point for 0.01µF capacitor to OUT to stabilize capacitive loads up to 10,000pF |
| V+ | Positive Supply Rail | Connects to positive supply; internal bias network references SHUTDOWN pin to V+ |
| SHUTDOWN | Bias Control Input | Current-sinking terminal: open or pulled to V+ disables amplifier; resistor to ground sets quiescent current |
| +IN | Noninverting Input | High-impedance (10MΩ) input with ±5V differential clamp; used for unity-gain buffer configurations |
| –IN | Inverting Input | Current-input node for feedback network; requires low-stray-capacitance routing to maintain stability |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar current feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6720MA/NOPB | Lower output current (120mA), higher bandwidth (1.8GHz), no shutdown or COMP pin | Optimized for RF/IF gain blocks, not high-current cabling or video distribution | Choose LMH6720MA/NOPB only when bandwidth >500MHz is required and load current <150mA |
| THS3091D | Higher slew rate (2750V/µs), same 1.1A output, but limited to ±15V max supply and no adjustable supply current | Targeted at high-speed oscilloscope front-ends and pulsed laser drivers | Choose THS3091D when ultra-fast transient response is critical and thermal management permits fixed 12mA quiescent current |
Compared with LMH6720MA/NOPB and THS3091D, the LT1210IR#TRPBF uniquely balances high output current, capacitive-load stability, and programmable power consumption - making it suitable for cost-sensitive, thermally constrained video and telecom infrastructure where adjustable bias and robust short-circuit protection are essential.

FAQ
What is the maximum capacitive load the LT1210IR#TRPBF can drive stably?
The LT1210IR#TRPBF is stable with up to 10,000pF capacitive loads when the COMP pin is connected to the OUT pin via a 0.01µF capacitor. This configuration eliminates peaking and maintains ≤1dB flatness to 40MHz. Without COMP, stability degrades significantly beyond 200pF. The LT1210IR#TRPBF's ability to drive large capacitive loads makes it ideal for LCD timing controllers and DAC output buffering where long traces or display panels introduce substantial capacitance.
How does the SHUTDOWN pin function on the LT1210IR#TRPBF?
The SHUTDOWN pin on the LT1210IR#TRPBF is a current-sinking terminal referenced to V+. When left open or pulled to V+, the device enters shutdown mode with supply current <200µA and output impedance ~70pF. When a resistor is connected from SHUTDOWN to ground, quiescent current scales linearly - e.g., 82kΩ yields ~9mA at ±15V. This feature enables dynamic power scaling in battery-powered instruments and thermal management in high-density layouts. The LT1210IR#TRPBF's shutdown transition time is ~1µs, supporting rapid enable/disable sequencing.
What package type is used for the LT1210IR#TRPBF?
The LT1210IR#TRPBF uses the 7-lead Plastic DD (R package), also known as DDPAK, with an exposed metal tab electrically connected to V+. This surface-mount package supports ±15V operation and offers θJA = 27°C/W with 1000 mm² copper area on the PCB topside. It is distinct from the SO-16 variant (LT1210CS#TRPBF) and TO-220 variant (LT1210CT7#PBF). The LT1210IR#TRPBF's DD package provides superior thermal performance compared to SO-16 for ±15V applications while maintaining compact footprint.
Can the LT1210IR#TRPBF operate from a single supply?
Yes, the LT1210IR#TRPBF supports single-supply operation, though its specified performance is characterized for split supplies (±5V to ±15V). When operated from a single supply (e.g., +10V and ground), input common-mode range and output swing are constrained by rail proximity - VIN must remain within ±2V of mid-rail for ±5V equivalents, and VOUT swing is reduced by ~1.5V from each rail. For optimal linearity and distortion performance, split supplies are recommended. The LT1210IR#TRPBF's internal architecture does not require matched rails, but offset voltage drift increases ~500µV per volt of supply mismatch.
What is the typical slew rate of the LT1210IR#TRPBF under standard conditions?
The LT1210IR#TRPBF has a typical slew rate of 900V/µs at AV = 2 with RL = 10Ω and ±15V supplies, measured per Note 7 in the datasheet. This value varies with gain configuration: it reaches ~1100V/µs in inverting mode (AV = –1) and drops to ~770V/µs in unity-gain noninverting mode. Slew rate is also affected by feedback resistor value and supply voltage - lower RF or higher VS increases slew rate. The LT1210IR#TRPBF's current-feedback topology means slew rate depends on output-stage current delivery, not just internal compensation, enabling predictable high-speed behavior across configurations.
