Product details
Overview
LT6203IMS8#PBF from Analog Devices (formerly Linear Technology) is a dual rail-to-rail input/output, ultralow-noise operational amplifier optimized for low-power signal conditioning. It delivers 1.9nV/√Hz input voltage noise at 100kHz, 100MHz gain bandwidth, and 25V/µs slew rate while drawing only 2.5mA per amplifier at 5V supply. It operates from 2.5V to 12.6V and is specified over –40°C to +85°C, making it ideal for precision battery-powered instrumentation and DSL receiver front-ends.
For engineers reviewing the LT6203IMS8#PBF datasheet, LT6203IMS8#PBF pinout, LT6203IMS8#PBF application, or LT6203IMS8#PBF equivalent, key selection criteria include its rail-to-rail output swing (within 50mV of rails at 5mA), low distortion (–80dBc at 1MHz), and guaranteed performance across industrial temperature range without derating.
Technical Context
The LT6203IMS8#PBF integrates two fully independent, unity-gain-stable amplifiers in an 8-pin MSOP package with standard op amp pinout. Its bipolar input stage enables low input bias current (±7.0µA typ) and high common-mode rejection (90dB typ), while the output stage supports ±30mA drive into resistive loads and maintains rail-to-rail swing under load.
It features a wide supply range (2.5V to 12.6V), operates down to 3V minimum supply, and maintains stable AC performance-including 100MHz GBW and 25V/µs slew rate-across temperature and supply variations, enabling direct replacement in legacy ±5V or single-supply 3V/5V systems without redesign.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Noise Voltage Density | 1.9nV/√Hz at 100kHz - enables high-resolution sensor signal amplification without adding measurable noise floor |
| Gain Bandwidth Product | 100MHz - supports closed-loop gains up to 10 at 10MHz or unity gain at full 100MHz, suitable for active filters and ADC drivers |
| Slew Rate | 25V/µs - ensures faithful reproduction of fast transients in video or communication signals up to ~4MHz full-power bandwidth |
| Supply Current per Amp | 2.5mA at 5V - allows dual-channel operation under 5.1mA total, critical for battery-backed data acquisition systems |
| Input Offset Voltage | 0.2mV max (typ 0.1mV) at 25°C - reduces DC error in precision gain stages and reference buffers |
| Output Swing | Within 50mV of rails at 5mA load - maximizes dynamic range in single-supply 3V/5V systems driving SAR ADCs or analog switches |
| CMRR | 90dB typical - rejects common-mode interference in noisy industrial environments or unshielded sensor interfaces |
Pinout & Package
LT6203IMS8#PBF is housed in an 8-lead plastic MSOP (MS8) package, 3mm × 3mm, 0.65mm pitch, with exposed pad thermally connected to V–. Pinout follows industry-standard dual op amp configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Delivers rail-to-rail buffered signal; capable of ±30mA sink/source |
| 2 (–IN A) | Inverting input A | Differential node for feedback networks; high-impedance (4MΩ common-mode) |
| 3 (+IN A) | Non-inverting input A | High-impedance sensor or reference interface point; includes rail-to-rail common-mode range |
| 4 (V–) | Negative supply | Reference for both amplifiers; undersurface metal pad must be soldered for thermal performance |
| 5 (V+) | Positive supply | Accepts 2.5V to 12.6V; PSRR of 74dB minimizes supply ripple coupling |
| 6 (OUT B) | Amplifier B output | Independent output channel; identical specs and drive capability as OUT A |
| 7 (–IN B) | Inverting input B | Second differential input; matched offset and CMRR to channel A within 0.3mV and 85dB |
| 8 (+IN B) | Non-inverting input B | Second high-Z input; supports independent signal paths in dual-channel applications |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode range extends beyond rails (V– – 0.1V to V+ + 0.1V); output swings to within 50mV of rails at 5mA, preserving full signal headroom |
| Ultralow noise | 1.9nV/√Hz input voltage noise + 1.1pA/√Hz input current noise - optimal for low-level transducer amplification without added Johnson noise penalty |
| Unity-gain stability | Stable with capacitive loads ≤100pF and no external compensation required - simplifies layout in high-speed sensor interfaces |
| Industrial temp grade | Specified from –40°C to +85°C with no parameter derating - eliminates need for thermal margining in outdoor or factory-floor deployments |
| Low distortion | –80dBc harmonic distortion at 1MHz - meets fidelity requirements for DSL line receivers and audio preamps |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-noise op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4897-2ARMZ | Lower noise (1.0nV/√Hz), higher supply current (3.6mA/amp), narrower supply range (3–10V) | Better for ultra-low-noise photodiode amps; less suitable for 2.5V or 12V systems | Choose when noise dominates budget and supply is tightly regulated at 5V |
| OPA2350UA | Higher noise (7nV/√Hz), lower supply current (1.8mA/amp), rail-to-rail I/O, same MSOP-8 package | Preferred for ultra-low-power sensor nodes where noise >5nV/√Hz is acceptable | Choose when battery life is critical and system SNR allows higher noise floor |
Compared with ADA4897-2ARMZ and OPA2350UA, the LT6203IMS8#PBF uniquely balances ultralow noise (1.9nV/√Hz), low power (2.5mA), and wide supply range (2.5–12.6V) in a temperature-qualified industrial-grade part-making it the optimal choice for DSL, portable test equipment, and multi-supply mixed-signal systems.

FAQ
What is the maximum supply voltage rating for LT6203IMS8#PBF?
The absolute maximum total supply voltage (V+ to V–) for LT6203IMS8#PBF is 12.6V. Operation beyond this risks permanent damage. The device is fully specified from 2.5V to 12.6V supply, with guaranteed performance including 100MHz GBW and rail-to-rail output swing across that range. At 12V supply, supply current remains within 3.0mA per amplifier.
Does LT6203IMS8#PBF support true rail-to-rail input common-mode range?
Yes, LT6203IMS8#PBF supports rail-to-rail input common-mode range: its inputs operate from V– – 0.1V to V+ + 0.1V, exceeding the supply rails. This enables direct interfacing with sensors or DACs that swing to the rails, and eliminates level-shifting circuitry in single-supply systems. Input resistance is 4MΩ common-mode and 12kΩ differential-mode.
What is the output drive capability of LT6203IMS8#PBF?
LT6203IMS8#PBF delivers ±30mA minimum short-circuit output current per amplifier and sustains rail-to-rail swing into 1kΩ loads. At 5mA load, output saturates within 50mV of each rail (V+ and V–). It drives capacitive loads up to 100pF stably without external compensation, supporting direct connection to ADC inputs and long PCB traces.
Is LT6203IMS8#PBF pin-compatible with other dual op amps in MSOP-8?
LT6203IMS8#PBF uses the industry-standard dual op amp pinout in MSOP-8: pins 1/6 = outputs, 2/7 = inverting inputs, 3/8 = non-inverting inputs, 4 = V–, 5 = V+. It is pin-compatible with OP2177, ADA4077-2, and OPA2350UA in the same package, though electrical specs (noise, speed, supply range) differ significantly-always verify loop stability and signal chain performance.
What is the operating temperature range for LT6203IMS8#PBF?
The LT6203IMS8#PBF is rated for –40°C to +85°C ambient operating temperature (I-grade), with all electrical specifications guaranteed across this range. It is not the H-grade (–40°C to +125°C) variant; the 'I' suffix in the part number explicitly denotes industrial temperature qualification, validated per JEDEC JESD22-A108.
