Product details
Overview
LT1816CMS8#PBF from Analog Devices (formerly Linear Technology) is a dual, high-speed, programmable-current operational amplifier in an 8-lead MSOP package. It delivers 220MHz gain-bandwidth, 1500V/µs slew rate, and 6.5mA per amplifier supply current at ±5V, with unity-gain stability and 6nV/√Hz input noise-ideal for precision video buffering and active filter stages in instrumentation systems.
For engineers reviewing the LT1816CMS8#PBF datasheet, LT1816CMS8#PBF pinout, LT1816CMS8#PBF application, or LT1816CMS8#PBF equivalent, key selection criteria include its programmable ISET pin for low-power mode (1.5mA), ±3.5V input CMR at ±5V supplies, 50mA output drive into 100Ω, and guaranteed operation from –40°C to 85°C in the MS8 package.
Technical Context
The LT1816CMS8#PBF implements a voltage-feedback topology with current-feedback slewing characteristics, enabling fast transient response without sacrificing DC accuracy. Its input stage uses complementary NPN/PNP emitter followers for bias current cancellation, supporting differential input voltages up to ±6V (transient only).
It features an ISET pin that allows dynamic adjustment of supply current and bandwidth: full-speed mode (6.5mA, 220MHz GBW) with ≤75Ω to V–, or low-power mode (1.5mA, 50MHz GBW) with 40kΩ to V–. Output drives ±3.5V into 100Ω at ±5V supplies and swings 1V to 4V on single 5V with 100Ω load referenced to 2.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 220MHz - supports stable closed-loop operation up to 100MHz in AV = 2 configuration with 50Ω source/load. |
| Slew Rate | 1500V/µs - enables clean 5MHz, 2VP-P output into 100Ω with –70dB THD in inverting gain-of-–1. |
| Supply Current (per amp) | 6.5mA at ±5V - balances speed and power; reduces to 1.5mA in low-power mode via ISET pin. |
| Input Offset Voltage | ≤2.0mV (max, –40°C to 85°C) - ensures <100µV error in 50mV full-scale sensor signal conditioning. |
| Input Noise Density | 6nV/√Hz at 10kHz - maintains SNR >70dB for 10MHz baseband signals in data acquisition front-ends. |
| Output Drive | ±50mA into 100Ω - sustains ±3.5V swing under heavy capacitive + resistive loads typical in cable driver applications. |
| Common-Mode Range | ±3.5V at ±5V supplies - accommodates rail-to-rail input signals in ±5V industrial analog interfaces. |
Pinout & Package
LT1816CMS8#PBF is housed in an 8-lead plastic MSOP (MS8) package, 3mm × 3mm, 1.1mm height, with exposed pad thermally connected to V–.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT A | Amplifier A output | Drives loads up to ±50mA; requires local 0.01µF bypass to V– for stability. |
| 2: –IN A | Inverting input A | High-impedance node; sensitive to layout-keep trace short and guard with ground. |
| 3: +IN A | Non-inverting input A | Matches –IN A; balanced source resistance minimizes offset from 8µA max input bias current. |
| 4: V– | Negative supply | Reference for ISET pin; connects internally to exposed pad for thermal performance. |
| 5: V+ | Positive supply | Accepts ±1.25V to ±5.5V; PSRR ≥75dB ensures immunity to supply ripple. |
| 6: OUT B | Amplifier B output | Independent output; channel separation ≥80dB prevents crosstalk in dual-channel systems. |
| 7: –IN B | Inverting input B | Electrically isolated from Channel A; supports independent feedback networks. |
| 8: +IN B | Non-inverting input B | Same DC specs as +IN A; enables matched dual-path signal processing. |
Key Features

|---|---|
| Programmable supply current | ISET pin enables seamless transition between full-speed (6.5mA) and low-power (1.5mA) modes without external control logic. |
| Unity-gain stable | Operates reliably at AV = 1 with no external compensation-reduces BOM count in buffer designs. |
| High slew rate + low distortion | 1500V/µs slew with –70dB THD at 5MHz enables composite video amplification without ghosting or ringing. |
| Wide input common-mode range | ±3.5V at ±5V supplies allows direct interfacing with ±3.3V logic and legacy ±5V DACs/ADCs. |

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 (4nV/√Hz), lower supply current (3.5mA), but 1GHz GBW and no ISET pin. | Optimized for ultra-low-noise photodiode amps; lacks programmable power for duty-cycled systems. | Select when lowest noise dominates over programmability and cost. |
| LMH6629MA/NOPB | Higher slew rate (3000V/µs), higher supply current (12.5mA), no ISET, SO-8 only. | Better for RF IF amplification; unsuitable where low-power mode or MSOP footprint is required. | Select for maximum speed in fixed-power systems with SO-8 layout compatibility. |
Compared with ADA4897-2ARMZ and LMH6629MA/NOPB, the LT1816CMS8#PBF uniquely combines programmable current, MSOP footprint, and 220MHz GBW-making it optimal for space-constrained, battery-aware instrumentation where dynamic power scaling matters more than absolute noise floor or peak slew rate.

FAQ
What is the maximum operating temperature range for the LT1816CMS8#PBF?
The LT1816CMS8#PBF is specified for operation from –40°C to 85°C and is guaranteed across this full industrial temperature range. Its MS8 package has θJA = 250°C/W, and junction temperature must remain below 150°C under all conditions-requiring thermal design consideration at high ambient or load currents.
How does the ISET pin function on the LT1816CMS8#PBF?
The ISET pin on the LT1816CMS8#PBF controls supply current and bandwidth: connecting it to V– through ≤75Ω enables full-speed mode (6.5mA, 220MHz GBW), while a 40kΩ resistor enables low-power mode (1.5mA, 50MHz GBW). The LT1816CMS8#PBF datasheet specifies exact current vs. RSET curves and guarantees performance at both extremes.
Can the LT1816CMS8#PBF drive a 100Ω load to ±3.5V with ±5V supplies?
Yes-the LT1816CMS8#PBF delivers ±50mA output current and achieves ±3.5V output swing into 100Ω with ±5V supplies, as confirmed in the Electrical Characteristics table (VOUT = ±3.5V, RL = 100Ω, TA = –40°C to 85°C). This makes it suitable for driving coaxial video lines and low-impedance active filters.
Is the LT1816CMS8#PBF unity-gain stable?
Yes-the LT1816CMS8#PBF is explicitly unity-gain stable and requires no external compensation for AV = 1 configurations. Its internal compensation ensures phase margin >40° at unity gain, enabling robust use as a voltage follower in high-frequency signal routing without risk of oscillation.
What is the input voltage noise density of the LT1816CMS8#PBF?
The LT1816CMS8#PBF has an input voltage noise density of 6nV/√Hz at 10kHz, measured under standard conditions (VS = ±5V, TA = 25°C). This value remains stable across frequency and temperature, supporting high-fidelity signal amplification in 100kHz–10MHz bandwidth applications such as medical sensor front-ends and spectrum analyzers.
