Product details
Overview
LT1816AIMS#PBF from Analog Devices (formerly Linear Technology) is a dual, high-speed, programmable-supply-current operational amplifier in a 10-lead MSOP package. It delivers 220MHz gain-bandwidth, 1500V/µs slew rate, and 6.5mA per amplifier supply current at ±5V, with low 1.5mV max input offset voltage and 6nV/√Hz input noise-enabling precision video buffering and active filter design in industrial instrumentation.
For engineers reviewing the LT1816AIMS#PBF datasheet, LT1816AIMS#PBF pinout, LT1816AIMS#PBF application, or LT1816AIMS#PBF equivalent, key selection criteria include its dual-channel configuration, ISET-programmable current mode (1–2mA low-power option), ±3.5V input common-mode range at ±5V supplies, and guaranteed –40°C to +85°C operation in the MSOP package.
Technical Context
The LT1816AIMS#PBF employs a voltage-feedback topology with current-feedback slewing behavior, enabling both high DC accuracy and fast transient response. Its input stage uses complementary NPN/PNP emitter followers for low input bias current (±8µA max) and first-order bias cancellation.
It supports dual supply (±1.25V to ±5.5V) and single 2.5V–5V operation, with rail-to-rail output swing into 100Ω loads (±3.5V at ±5V supplies). The ISET pin allows dynamic switching between full-speed (6.5mA) and low-power (1.5mA) modes via external resistor programming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 220MHz - enables stable unity-gain operation and supports >100MHz signal paths in active filters or RF IF stages. |
| Slew Rate | 1500V/µs - ensures minimal distortion on fast 5MHz, 2VP-P signals driving 100Ω loads (THD = –70dB). |
| Supply Current per Amplifier | 6.5mA (full speed), 1.5mA (low power) - selectable via ISET pin resistor; reduces thermal load in space-constrained designs. |
| Input Offset Voltage | 1.5mV max - supports DC-coupled precision amplification without significant calibration overhead. |
| Input Noise Voltage Density | 6nV/√Hz at 10kHz - critical for low-noise sensor front-ends and high-fidelity analog signal chains. |
| Operating Temperature Range | –40°C to +85°C - qualified for industrial control, test equipment, and automotive cabin electronics. |
| Output Drive Capability | ±50mA min into 100Ω - sustains ±3.5V swing at ±5V supplies, suitable for driving coaxial cables or ADC input buffers. |

| 7 | OUT B | Amplifier B output; fully independent channel with identical AC/DC specs to OUT A. |
| 8 | –IN B | Inverting input of Amp B; matched to –IN A for interleaved or differential pair configurations. |
| 9 | +IN B | Non-inverting input of Amp B; enables dual-channel instrumentation or stereo signal processing. |
| 10 | ISET | Current programming terminal; sinking ≤200µA; sets supply current from 1.5mA (40kΩ to V–) to 6.5mA (≤75Ω to V–). |
Key Features
| Feature | Design Value |
|---|---|
| Programmable supply current | Adjustable from 1.5mA to 6.5mA per amplifier via ISET pin resistor-enables dynamic power scaling in battery-powered or thermally constrained systems. |
| Unity-gain stable | Guaranteed stable at AV = 1 with 500Ω load; eliminates need for external compensation in buffer applications. |
| Low input offset drift | 10µV/°C max over –40°C to +85°C-reduces calibration frequency in precision measurement front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4897-2ARMZ | Lower 1nV/√Hz noise, 220MHz GBW, but fixed 3.7mA supply current and no ISET programmability. | Lacks low-power mode; unsuitable where dynamic current scaling is required for thermal or battery life management. | Prefer when ultra-low noise dominates over power flexibility. |
| LMH6629MA/NOPB | Higher 2.9nV/√Hz noise, 1.5GHz GBW, 100mA output drive, but 12.5mA supply current and no temperature-rated –40°C to +85°C guarantee. | Over-specified for 220MHz needs; higher quiescent power and unqualified extended temperature range limit industrial use. | Prefer only for >500MHz small-signal bandwidth requirements with relaxed thermal constraints. |
Compared with ADA4897-2ARMZ and LMH6629MA/NOPB, the LT1816AIMS#PBF uniquely balances programmable current, guaranteed industrial temperature operation, and 220MHz performance in a compact MSOP-making it optimal for cost-sensitive, thermally constrained dual-channel analog signal conditioning.

FAQ
What is the maximum supply voltage for the LT1816AIMS#PBF?
The LT1816AIMS#PBF has an absolute maximum total supply voltage (V+ to V–) of 12.6V. For reliable operation, it is specified across ±1.25V to ±5.5V dual supplies or 2.5V–5V single supplies. Exceeding these ranges risks permanent damage per Absolute Maximum Ratings.
Does the LT1816AIMS#PBF support single-supply operation?
Yes, the LT1816AIMS#PBF operates from a single 2.5V to 5V supply. With a 5V supply and output loaded to 2.5V, it delivers 1V to 4V output swing. Input common-mode range spans 0.9V to 4.1V, supporting DC-coupled inputs in single-supply configurations.
How does the ISET pin function on the LT1816AIMS#PBF?
The ISET pin on the LT1816AIMS#PBF sinks current to set supply current per amplifier. Connecting it to V– via ≤75Ω enables full-speed mode (6.5mA); using a 40kΩ resistor enables low-power mode (1.5mA). The LT1816AIMS#PBF datasheet specifies exact current vs. RSET curves and corresponding GBW/slew rate trade-offs.
Is the LT1816AIMS#PBF unity-gain stable?
Yes, the LT1816AIMS#PBF is unity-gain stable into 500Ω loads. It requires no external compensation in AV = 1 configurations, simplifying design of high-fidelity buffers for ADC drivers or video distribution. Stability is verified across –40°C to +85°C and all supply voltages.
What is the thermal performance of the LT1816AIMS#PBF in its MSOP package?
The LT1816AIMS#PBF in the 10-lead MSOP package has θJA = 250°C/W with short PCB traces. Its underside metal pad connects internally to V–, allowing direct thermal coupling to a ground plane or copper pour to reduce junction temperature-critical when delivering ±50mA into 100Ω loads at elevated ambient temperatures.
