Product details
Overview
LT6202CS5#TRMPBF from Analog Devices (formerly Linear Technology) is a single-channel, rail-to-rail input/output ultralow-noise operational amplifier with 1.9nV/√Hz input voltage noise, 100MHz gain bandwidth product, and 2.5mA supply current per amplifier. It operates from 2.5V to 12.6V supplies and delivers ±30mA output drive, making it ideal for precision signal conditioning in battery-powered data acquisition systems.
For engineers reviewing the LT6202CS5#TRMPBF datasheet, LT6202CS5#TRMPBF pinout, LT6202CS5#TRMPBF application, or LT6202CS5#TRMPBF equivalent, key selection criteria include its 1.9nV/√Hz noise floor at 100kHz, rail-to-rail swing capability down to 5mV from rails under no load, and guaranteed performance across –40°C to 85°C for industrial-grade signal chains.
Technical Context
The LT6202CS5#TRMPBF employs a proprietary low-noise bipolar input stage optimized for unity-gain stability and wide supply range operation. Its architecture maintains 90dB typical CMRR and 74dB PSRR while supporting rail-to-rail common-mode input range and full-swing output into 1kΩ loads.
It achieves 25V/µs slew rate and 100MHz GBW with <–80dBc harmonic distortion at 1MHz, enabling high-fidelity amplification in active filters, A/D driver stages, and DSL receiver front-ends without external compensation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4898-1ARMZ | Higher 1.1nV/√Hz noise, 220MHz GBW, 3.5mA supply current, SO-8 package | Better suited for >50MHz closed-loop designs; less optimal for ultra-low-power battery use | Select when higher speed and lower noise outweigh power budget constraints |
| OPA320AIDBVR | Lower 7nV/√Hz noise, 20MHz GBW, 1.6mA supply current, SOT-23-5 package | Optimized for <10MHz precision DC-coupled applications; insufficient bandwidth for RF/IF stages | Select for cost-sensitive, low-bandwidth sensor interfaces where 100MHz is unnecessary |
Compared with ADA4898-1ARMZ and OPA320AIDBVR, the LT6202CS5#TRMPBF uniquely balances 100MHz bandwidth, 1.9nV/√Hz noise, and 2.5mA consumption in a space-constrained TSOT-23 package-making it the preferred choice for high-fidelity, medium-speed signal chains where board area and power are jointly constrained.

FAQ
What is the maximum supply voltage for the LT6202CS5#TRMPBF?
The LT6202CS5#TRMPBF has an absolute maximum total supply voltage (V+ to V–) of 12.6V. Operation beyond this rating risks permanent damage. For reliable long-term performance, Analog Devices specifies operation from 2.5V to 12.6V, with full electrical characterization at 3V, 5V, and ±5V supplies. The LT6202CS5#TRMPBF maintains specified noise, bandwidth, and output swing across this entire range.
Does the LT6202CS5#TRMPBF require external compensation for unity-gain stability?
No, the LT6202CS5#TRMPBF is internally compensated for unity-gain stability. It does not require external capacitors or feedback network adjustments to remain stable at gain = 1. This is confirmed in the device's datasheet under "Features" and verified in typical application circuits. The LT6202CS5#TRMPBF remains stable driving capacitive loads up to 100pF directly, though larger loads may benefit from series output resistance per layout guidelines.
What is the input offset voltage specification for the LT6202CS5#TRMPBF at 25°C and 5V supply?
At TA = 25°C and VS = 5V, the LT6202CS5#TRMPBF has a typical input offset voltage of 0.1mV and a maximum of 0.5mV when VCM = half supply. Under worst-case conditions (VCM = V+ to V–), the max offset rises to 2.2mV. These values are explicitly listed in the "ELECTRICAL CHARACTERISTICS" table on page 4 of the official datasheet. The LT6202CS5#TRMPBF's offset drift is 3.0µV/°C typical, ensuring predictable behavior across temperature.
Can the LT6202CS5#TRMPBF drive a 50Ω load effectively?
The LT6202CS5#TRMPBF is rated for ±30mA short-circuit output current and delivers ≥30mA into resistive loads, but continuous 50Ω driving at full swing requires careful thermal consideration. At 5V supply and 2V output swing, it sources ~40mA - exceeding its 30mA min spec and approaching thermal limits in the TSOT-23 package. For sustained 50Ω drive, use current-limiting series resistance or consider the dual LT6203 in SO-8 for better power dissipation. The LT6202CS5#TRMPBF is best applied with ≥100Ω loads or pulsed 50Ω operation.
Is the LT6202CS5#TRMPBF pin-compatible with other op amps in SOT-23-5 packages?
The LT6202CS5#TRMPBF uses standard op amp pinout for SOT-23-5: Pin 1 = OUT, Pin 2 = V–, Pin 3 = +IN, Pin 4 = –IN, Pin 5 = V+. This matches industry-standard assignments (e.g., OPA320, AD8605, MCP6001), enabling drop-in replacement in many layouts - provided supply range, bandwidth, noise, and output drive requirements align. However, no formal pin-compatibility claim is made by Analog Devices; validation of loop stability and transient response is required when substituting the LT6202CS5#TRMPBF into existing designs.
