Product details
Overview
LT6202CS8#TRPBF from Analog Devices (formerly Linear Technology) is a single-channel, rail-to-rail input/output operational amplifier optimized for low-noise, low-power signal conditioning in 3V–5V systems. It delivers 1.9nV/√Hz input voltage noise at 100kHz, 100MHz gain bandwidth, 25V/µs slew rate, and draws only 2.5mA per amplifier at 5V - enabling high-fidelity analog front-ends in battery-powered data acquisition and precision sensor interfaces.
For engineers reviewing the LT6202CS8#TRPBF datasheet, LT6202CS8#TRPBF pinout, LT6202CS8#TRPBF application, or LT6202CS8#TRPBF equivalent, key selection criteria include its guaranteed 0°C to 70°C operation, 8-pin SO package with standard op amp pinout, rail-to-rail output swing within 35mV of rails at 5mA, and –80dBc harmonic distortion at 1MHz - critical for driving SAR ADCs and active filter stages.
Technical Context
The LT6202CS8#TRPBF employs a proprietary bipolar complementary input stage enabling simultaneous rail-to-rail input common-mode range (including both supply rails) and ultra-low 1.9nV/√Hz voltage noise. Its unity-gain-stable architecture supports direct use in buffer, gain, and differential configurations without external compensation.
It maintains full performance across 2.5V to 12.6V total supply range, with specified behavior at 3V, 5V, and ±5V supplies. CMRR of 90dB typ and PSRR of 74dB typ ensure robust rejection of supply and common-mode interference in mixed-signal environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4898-1ARMZ | Higher 1.05nV/√Hz noise, 290MHz GBW, 190V/µs slew rate, 12.6mA supply current | Better for wideband (>50MHz) applications; overkill for ≤10MHz data acquisition where power matters | Select when bandwidth/noise trade-off favors ultra-low noise over quiescent power |
| OPA350UA | 2.5nV/√Hz noise, 38MHz GBW, 22V/µs slew rate, 5.7mA supply current, same 8-pin SO package | Lower bandwidth and higher noise limit use in high-fidelity audio or fast-settling ADC drivers | Choose for cost-sensitive designs requiring proven TI support and compatible footprint |

FAQ
What is the maximum supply voltage rating for the LT6202CS8#TRPBF?
The LT6202CS8#TRPBF has an absolute maximum total supply voltage (V+ to V–) of 12.6V. Operation beyond this rating risks permanent damage. For reliable long-term use, Analog Devices specifies functional operation from 2.5V to 12.6V, with full parametric guarantees at 3V, 5V, and ±5V supplies. The LT6202CS8#TRPBF must not be operated with supply voltages exceeding 12.6V under any condition.
Does the LT6202CS8#TRPBF support true rail-to-rail input common-mode range?
Yes, the LT6202CS8#TRPBF supports true rail-to-rail input common-mode range: its inputs operate from V– to V+, including both supply rails. This is confirmed in the datasheet's "Input Common Mode Range Includes Both Rails" feature and verified by electrical characteristics showing valid operation at VCM = V+ and VCM = V– across all temperature grades. The LT6202CS8#TRPBF achieves this using a complementary bipolar input stage.
What is the guaranteed input offset voltage specification for LT6202CS8#TRPBF at 25°C and 5V supply?
At TA = 25°C and VS = 5V, the LT6202CS8#TRPBF has a guaranteed maximum input offset voltage of 0.7mV when VCM = half supply, and 2.5mV when VCM spans the full rail-to-rail range (V– to V+). These values apply to the C-grade (0°C to 70°C) version and are explicitly listed in the "ELECTRICAL CHARACTERISTICS" table on page 4 of the official datasheet. The LT6202CS8#TRPBF's typical VOS is 0.1mV under the same conditions.
Can the LT6202CS8#TRPBF drive heavy capacitive loads without instability?
The LT6202CS8#TRPBF is unity-gain stable but not inherently optimized for heavy capacitive loads. Driving >100pF directly may cause peaking or ringing due to phase margin reduction. For loads >100pF (e.g., ADC input capacitance plus PCB trace), Analog Devices recommends isolating the output with a small series resistor (10–50Ω) and/or using the recommended compensation network shown in Figure 4 of the datasheet. This applies equally to all variants of the LT6202CS8#TRPBF.
Is the LT6202CS8#TRPBF pin-compatible with other op amps in the same SO-8 package?
The LT6202CS8#TRPBF uses a nonstandard SO-8 pinout: pins 1, 6, and 7 are NC (no connect), unlike industry-standard SO-8 op amps (e.g., LM358, OPA234) which use those pins for shutdown, output, or other functions. Therefore, the LT6202CS8#TRPBF is not pin-compatible with generic SO-8 op amps. Direct replacement requires PCB layout revision. Its pinout matches only other members of the LT620x family in S8 packaging, such as LT6203CS8#TRPBF (dual version).
