Product details
Overview
LT6203CS8#PBF from Analog Devices (formerly Linear Technology) is a dual rail-to-rail input/output, ultralow-noise operational amplifier with 1.9nV/√Hz input voltage noise, 100MHz gain bandwidth product, and 2.5mA per amplifier supply current at 5V. It operates from 2.5V to 12.6V supplies and delivers ±30mA output drive, making it ideal for precision signal conditioning in low-power data acquisition systems.
For engineers reviewing the LT6203CS8#PBF datasheet, LT6203CS8#PBF pinout, LT6203CS8#PBF application, or LT6203CS8#PBF equivalent, key selection criteria include its guaranteed 0°C to 70°C operating range, SO-8 package with standard dual op amp pinout, rail-to-rail swing capability, and harmonic distortion below –80dBc at 1MHz.
Technical Context
The LT6203CS8#PBF integrates two independent unity-gain-stable amplifiers optimized for low-supply, high-fidelity analog signal paths. Its architecture supports full rail-to-rail common-mode input range (including both supply rails) and rail-to-rail output swing, enabling operation in single-supply configurations down to 2.5V.
It features matched channel performance including ≤0.9mV input offset voltage match and ≥83dB CMRR match over 0°C to 70°C, with low input bias current shift (≤11.3µA) across the input common-mode range - critical for high-impedance sensor interfaces and active filter stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Noise Voltage Density | 1.9nV/√Hz at 100kHz - enables high-resolution measurement of µV-level signals without dominant amplifier noise contribution |
| Gain Bandwidth Product | 100MHz - supports stable closed-loop gain up to 10× at 10MHz or unity gain at 100MHz for wideband filtering |
| Supply Current per Amp | 2.5mA max at 5V - allows dual-channel operation under 5.5mW total quiescent power at 5V |
| Input Common-Mode Range | Includes both rails (V– to V+) - eliminates level-shifting requirements in single-supply front-end designs |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs or downstream stages without headroom loss |
| Harmonic Distortion | –80dBc at 1MHz - meets SNR requirements for 14-bit+ data acquisition at audio and IF frequencies |
| Operating Temperature | 0°C to 70°C - qualified for commercial-grade instrumentation and industrial control applications |
Pinout & Package
LT6203CS8#PBF is housed in an 8-lead plastic SO (Small Outline) package with standard dual op amp pinout and JEDEC MS-012AC footprint. Thermal resistance θJA = 190°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 | –IN A | Inverting input of Amplifier A - high-impedance node (4MΩ common-mode, 12kΩ differential) |
| 3 | +IN A | Non-inverting input of Amplifier A - accepts signals from V– to V+ without phase reversal |
| 4 | V– | Negative supply rail - also connects internally to exposed pad in DFN variants (not applicable to SO-8) |
| 5 | V+ | Positive supply rail - supports single-supply (2.5V–12.6V) or split-supply (±1.25V–±5V) operation |
| 6 | OUT B | Amplifier B output - electrically identical to OUT A; enables dual-channel signal processing |
| 7 | –IN B | Inverting input of Amplifier B - matched to –IN A for differential pair or parallel configurations |
| 8 | +IN B | Non-inverting input of Amplifier B - supports independent or correlated dual-channel sensing |

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 |
|---|---|---|---|
| AD8622ARZ | Lower noise (1.3nV/√Hz), higher supply current (3.5mA/Amp), same SO-8 package | Better SNR-critical applications; less suitable for ultra-low-power designs | Choose AD8622ARZ when noise dominates budget and power is secondary |
| OPA2350UA | Higher noise (7nV/√Hz), lower supply current (1.8mA/Amp), rail-to-rail I/O, SO-8 | Lower power consumption but insufficient for high-resolution sensor interfaces | Choose OPA2350UA only where power is constrained and noise < 10nV/√Hz is acceptable |
Compared with AD8622ARZ and OPA2350UA, the LT6203CS8#PBF uniquely balances ultralow noise (1.9nV/√Hz), moderate power (2.5mA/Amp), and robust 100MHz bandwidth - making it optimal for dual-channel, battery-aware precision signal chains requiring both fidelity and efficiency.

FAQ
What is the maximum supply voltage rating for LT6203CS8#PBF?
The absolute maximum total supply voltage (V+ to V–) for LT6203CS8#PBF is 12.6V. Operation beyond this rating risks permanent damage. The device is fully specified from 2.5V to 12.6V supply range, with performance validated at 3V, 5V, and ±5V conditions. Always observe derating guidelines in thermal design when operating near maximum ratings.
Does LT6203CS8#PBF support true rail-to-rail input common-mode range?
Yes, LT6203CS8#PBF supports input common-mode voltage from V– to V+, inclusive - verified across all supply voltages (2.5V to 12.6V) and temperature ranges. This allows direct interfacing with sensors or DACs operating at either supply rail without external clamping or level-shifting circuitry.
What is the typical output drive capability of LT6203CS8#PBF?
LT6203CS8#PBF delivers minimum ±30mA output current per amplifier into resistive loads. At 5V supply and ISINK = ISOURCE = 20mA, output swing is within 240mV of V– and 325mV of V+, confirming robust drive strength for driving ADC reference buffers, active filters, or moderate-capacitive loads up to 100pF.
Is LT6203CS8#PBF unity-gain stable?
Yes, LT6203CS8#PBF is explicitly unity-gain stable per manufacturer specification. It requires no external compensation and maintains phase margin >60° at gain = 1 across all process, voltage, and temperature corners - enabling direct use in voltage followers, transimpedance amplifiers, and other gain-of-one configurations.
What is the guaranteed operating temperature range for LT6203CS8#PBF?
LT6203CS8#PBF is rated for 0°C to 70°C ambient operating temperature (Commercial grade). This range is fully tested and guaranteed per datasheet specifications. For extended temperature operation, consider LT6203IS8#PBF (–40°C to 85°C) or LT6203HMS8#PBF (–40°C to 125°C), which share identical electrical performance but different qualification testing.
