Product details
Overview
LT1816CS8#PBF from Analog Devices (formerly Linear Technology) is a dual high-speed voltage-feedback operational amplifier with programmable supply current, 220MHz gain-bandwidth product, 1500V/µs slew rate, and ±5V or single 5V supply operation. It delivers ±3.5V output swing into 100Ω with ±5V supplies and drives video, RF, and data acquisition circuits requiring low distortion and fast settling.
For engineers reviewing the LT1816CS8#PBF datasheet, LT1816CS8#PBF pinout, LT1816CS8#PBF application, or LT1816CS8#PBF equivalent, key selection criteria include guaranteed 220MHz GBW at ±5V, programmable current mode (1–6.5mA per amplifier), 6nV/√Hz input noise, ±1.25V minimum supply, and SO-8 package compatibility with industrial temperature range (0°C to 70°C).
Technical Context
The LT1816CS8#PBF uses a voltage-feedback topology with current-feedback slewing characteristics, enabling both precision DC performance and wideband AC response. Its input stage employs complementary NPN/PNP emitter followers for bias current cancellation, supporting ±3.5V common-mode range on ±5V supplies and rail-to-rail output swing capability under load.
It features an ISET pin for supply current programming via external resistor (0–40kΩ), allowing dynamic trade-off between speed (220MHz → 30MHz) and power (6.5mA → 1mA per amplifier). Channel separation exceeds 80dB, and it remains unity-gain stable driving 100Ω loads with <25% overshoot and 15ns settling to 0.1%.
Key Specifications

| 3 | +IN A | Non-inverting input A - balanced source impedance recommended to cancel IB-induced offset |
| 4 | V– | Negative supply - connect to ground (single 5V) or –5V; ties ISET reference for current programming |
| 5 | V+ | Positive supply - decouple with 0.01µF ceramic + optional 1µF tantalum for high-current transients |
| 6 | –IN B | Inverting input B - independent channel; same layout rules as Pin 2 |
| 7 | +IN B | Non-inverting input B - electrically isolated from Channel A; supports differential or dual-path designs |
| 8 | OUT B | Amplifier B output - identical drive capability to Pin 1; enables dual-channel buffering or parallel drive |
Key Features

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 noise (4.5nV/√Hz), lower supply current (3.5mA), but 105MHz GBW and no ISET pin | Better for low-power, low-noise precision apps; unsuitable where >200MHz GBW or programmability required | Select when noise dominates over speed; avoid if programmable current or >150MHz bandwidth needed |
| LMH6629MA/NOPB | Higher slew (3800V/µs), higher supply current (12.5mA), no programmability, 1.5GHz GBW | Targeted at ultra-high-speed (>500MHz) apps; excessive power for 220MHz use cases | Choose only when >300MHz bandwidth is mandatory; overkill and inefficient for LT1816CS8#PBF's target use points |
Compared with ADA4897-2ARMZ and LMH6629MA/NOPB, the LT1816CS8#PBF uniquely balances 220MHz bandwidth, 1500V/µs slew, and on-the-fly current/speed adjustment - making it optimal for adaptive signal chains where power and performance must scale together.

FAQ
What supply voltages does the LT1816CS8#PBF support?
The LT1816CS8#PBF operates from ±1.25V to ±5.5V dual supplies or 2.5V to 5V single supply. At ±5V, it delivers ±3.5V output swing into 100Ω; on single 5V, output swings from 1V to 4V with 100Ω load referenced to 2.5V. Minimum supply is guaranteed by PSRR spec, not absolute rating.
Does the LT1816CS8#PBF have a programmable current feature?
Yes - the LT1816CS8#PBF includes an ISET pin that allows supply current per amplifier to be programmed from 1mA to 6.5mA using an external resistor (0–40kΩ) between ISET and V–. This adjusts gain-bandwidth from 30MHz to 220MHz and slew rate from 300V/µs to 1500V/µs, enabling dynamic power/performance scaling.
What is the maximum output current of the LT1816CS8#PBF?
The LT1816CS8#PBF delivers a minimum of ±50mA output current per amplifier when VOUT = ±3V and overdriven by 30mV. In low-power mode (ISET = 40kΩ), it still provides ±30mA. Short-circuit current is ±100mA (sinking or sourcing), with thermal derating above 85°C ambient.
Is the LT1816CS8#PBF unity-gain stable?
Yes - the LT1816CS8#PBF is unity-gain stable and specified to drive 100Ω loads in G=1 configuration with <25% overshoot and 15ns 0.1% settling time. It remains stable with capacitive loads up to 10pF; larger loads require isolation resistors (10–50Ω) between output and capacitance.
What package type is used for the LT1816CS8#PBF?
The LT1816CS8#PBF uses an 8-lead plastic SO (Small Outline) package (S8), 3.9mm × 4.9mm body size, 1.27mm lead pitch, with no internal connection to the exposed pad. It is RoHS-compliant and lead-free (PBF suffix), rated for 0°C to 70°C operation.
