Product details
Overview
LT6203IMS8#TRPBF from Analog Devices (formerly Linear Technology) is a dual rail-to-rail input/output ultralow-noise operational amplifier in an 8-lead MSOP package, delivering 1.9nV/√Hz input voltage noise, 100MHz gain bandwidth, and 25V/µs slew rate at 2.5mA per amplifier supply current. It operates from 2.5V to 12.6V supplies and is specified over –40°C to +85°C, targeting precision signal conditioning in low-power data acquisition and DSL receiver front-ends.
For engineers reviewing the LT6203IMS8#TRPBF datasheet, LT6203IMS8#TRPBF pinout, LT6203IMS8#TRPBF application, or LT6203IMS8#TRPBF equivalent, key selection criteria include its rail-to-rail output swing (within 260mV of rails at 15mA sink/source), channel-to-channel offset match (≤1.0mV), and guaranteed performance across industrial temperature range without derating.
Technical Context
The LT6203IMS8#TRPBF integrates two fully independent high-speed amplifiers with unity-gain stability, optimized for low-voltage signal chains requiring wide dynamic range and minimal distortion (<–80dBc at 1MHz). Its input stage supports common-mode voltages extending to both supply rails, and its output drives ≥30mA into resistive loads while maintaining rail-to-rail swing.
It features matched internal architecture enabling precise differential signaling-CMRR match ≤100dB and PSRR match ≤100dB-making it suitable for instrumentation-grade active filters and A/D driver stages where channel tracking and power-supply rejection are critical under varying load and supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Noise Density | 1.9nV/√Hz at 100kHz - enables sub-µV signal resolution in 10kHz bandwidths without dominating system noise floor |
| Gain Bandwidth | 100MHz - supports stable closed-loop gain ≥10 up to 10MHz, sufficient for antialiasing filter design |
| Slew Rate | 25V/µs - ensures faithful reproduction of 1.5VPP signals at 4MHz without slewing-induced distortion |
| Supply Current | 2.5mA per amplifier at 5V - allows dual-channel operation below 5.5mW total quiescent power |
| Input Offset Match | ≤1.0mV (ch-to-ch) - maintains <0.1% gain error in differential configurations with matched feedback networks |
| Output Drive | ≥30mA min - directly drives 100Ω transmission lines or ADC reference buffers without external boost |
| Operating Temp | –40°C to +85°C - qualified for industrial environments without thermal derating of AC specs |
Pinout & Package
LT6203IMS8#TRPBF is housed in an 8-lead plastic MSOP (MS8) package, 3mm × 3mm footprint, 1.1mm max height, with exposed pad thermally connected to V–. Pinout follows standard dual op amp configuration.
| Pin/Terminal | Circuit Role | Design Meaning |

| 3: +IN A | Non-inverting input A | Matches –IN A in bias current (≤0.6µA shift) and offset (≤1.0mV ch-to-ch) |
| 4: V– | Negative supply | Internally connected to exposed thermal pad; must be tied to lowest system potential |
| 5: V+ | Positive supply | Accepts 2.5V to 12.6V single supply or ±1.25V to ±5V split supply |
| 6: OUT B | Amplifier B output | Electrically identical to OUT A; independent output stage with same drive capability |
| 7: –IN B | Inverting input B | Matched to –IN A for CMRR ≥75dB and PSRR ≥60dB across temperature |
| 8: +IN B | Non-inverting input B | Same input capacitance (1.5pF diff) and noise current density (0.75pA/√Hz balanced) |

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 (3.5mA/amp), same MSOP-8 package | Better SNR-critical applications (e.g., photodiode TIA); less suitable for ultra-low-power designs | Select when noise dominates budget and >1mA extra supply current is acceptable |
| OPA2350UA | Higher noise (7nV/√Hz), lower GBW (38MHz), same rail-to-rail I/O and MSOP-8 | Cost-sensitive, moderate-speed applications (e.g., audio line drivers); insufficient for DSL or fast data acquisition | Select only if noise and bandwidth requirements are relaxed and cost is primary constraint |

FAQ
What is the maximum supply voltage for LT6203IMS8#TRPBF?
The absolute maximum total supply voltage (V+ to V–) for LT6203IMS8#TRPBF 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 per the official datasheet. Derating is not required up to 12.6V under normal thermal conditions.
Does LT6203IMS8#TRPBF support rail-to-rail input common-mode voltage?
Yes, LT6203IMS8#TRPBF supports rail-to-rail input common-mode voltage: its input stage operates with VCM extending from V– to V+, inclusive. This is explicitly confirmed in the "Features" section and electrical characteristics tables, enabling direct interfacing with grounded or rail-referenced sensors without level-shifting circuitry.
What is the guaranteed output drive capability of LT6203IMS8#TRPBF?
LT6203IMS8#TRPBF guarantees ≥30mA output current per amplifier (ISC = ±30mA at 5V supply), with rail-to-rail output swing maintained down to within 260mV of V+ and V– at 15mA load. This drive strength supports direct connection to 100Ω transmission lines, ADC input buffers, and moderate-current active filters without external boosting.
Is LT6203IMS8#TRPBF unity-gain stable?
Yes, LT6203IMS8#TRPBF is unity-gain stable. The datasheet explicitly states "Unity Gain Stable" in the Features list and confirms stability under closed-loop gains ≥1 without requiring external compensation components-a key advantage for buffer and gain-of-one configurations.
What temperature range is LT6203IMS8#TRPBF rated for?
LT6203IMS8#TRPBF is rated for operation from –40°C to +85°C (I-grade), with full electrical specifications guaranteed across this industrial temperature range. It is not the H-grade (–40°C to +125°C) variant; the 'I' in the part number denotes the –40°C to +85°C qualification, verified by production testing per Linear Technology/Analog Devices standards.
