Product details
Overview
LT6204CS#PBF from Analog Devices (formerly Linear Technology) is a quad rail-to-rail input/output low-noise operational amplifier optimized for precision signal conditioning in low-voltage, low-power systems. It delivers 1.9nV/√Hz input voltage noise, 100MHz gain bandwidth, 25V/µs slew rate, and operates from 2.5V to 12.6V supplies - enabling high-fidelity analog front-ends in battery-powered data acquisition and DSL receivers.
For engineers reviewing the LT6204CS#PBF datasheet, LT6204CS#PBF pinout, LT6204CS#PBF application, or LT6204CS#PBF equivalent, key selection criteria include its 0°C to 70°C temperature grade, 14-pin SO package, rail-to-rail output swing within 260mV of rails at 15mA load, and verified performance in active filters and A/D driver circuits.
Technical Context
The LT6204CS#PBF implements a unity-gain-stable voltage-feedback architecture with complementary bipolar input stage, enabling ultralow voltage noise and wide supply range compatibility. Its input common-mode range extends to both supply rails, and output drives ±30mA while maintaining rail-to-rail swing under load.
It features matched channel performance (e.g., 0.15mV typical input offset voltage match, 83dB typical CMRR match), low distortion (–80dBc at 1MHz), and stable operation across 3V, 5V, and ±5V configurations - making it suitable for multi-channel differential signal paths requiring channel-to-channel consistency.

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 |
|---|---|---|---|
| OPA211IDR | Lower noise (1.1nV/√Hz), higher supply current (3.6mA/amp), 45MHz GBW | Better for ultra-low-noise DC-coupled applications; less suitable for >10MHz signal paths | Select when noise dominates over bandwidth and power; verify thermal design for SO-8 dual vs SO-14 quad layout |
| AD8604ARUZ | Higher noise (12nV/√Hz), lower supply current (1.3mA/amp), 8MHz GBW, same SO-14 package | Targeted at micropower, low-frequency precision apps (e.g., medical sensors); insufficient for DSL or fast ADC drive | Choose only for sub-1MHz, battery-life-critical designs where noise <10nV/√Hz is acceptable |
Compared with OPA211IDR and AD8604ARUZ, LT6204CS#PBF uniquely balances 100MHz bandwidth, 1.9nV/√Hz noise, and quad SO-14 integration - making it optimal for space-constrained, wideband signal chains requiring multiple matched amplifiers without sacrificing speed or fidelity.

FAQ
What is the maximum supply voltage rating for LT6204CS#PBF?
The absolute maximum total supply voltage (V+ to V–) for LT6204CS#PBF is 12.6V. Operation beyond this risks permanent damage. The device is fully specified from 2.5V to 12.6V, with guaranteed performance at 3V, 5V, and ±5V supplies. At 12.6V, thermal limits must be observed - junction temperature must remain ≤150°C, requiring appropriate PCB copper area or heat sinking if output current exceeds 10mA per amplifier.
Does LT6204CS#PBF support true rail-to-rail input common-mode range?
Yes, LT6204CS#PBF supports rail-to-rail input common-mode voltage range: its inputs operate from V– to V+, including both supply rails. This is confirmed in the datasheet under "Input Common Mode Range Includes Both Rails" and validated by electrical characteristics showing functional operation at VCM = V– and VCM = V+. No external level-shifting is needed when interfacing with DACs, sensors, or other rail-referenced sources.
What is the typical output current drive capability of LT6204CS#PBF?
LT6204CS#PBF delivers a minimum output current of ±30mA per amplifier, as specified in the "Short-Circuit Current" parameter (±30mA at VS = 5V). Under normal linear operation, it sustains ±20mA while maintaining rail-to-rail swing (e.g., VOL = 240mV at ISINK = 20mA, VOH = 325mV at ISOURCE = 20mA, VS = 5V). This enables direct driving of cables, ADC input networks, or moderate-impedance loads without external buffers.
Is LT6204CS#PBF unity-gain stable?
Yes, LT6204CS#PBF is explicitly unity-gain stable, as stated in the product description and confirmed by application circuits in the datasheet (e.g., buffer configurations). No external compensation is required for gains ≥1. Stability is maintained across the full supply range (2.5V–12.6V) and temperature range (0°C–70°C), with phase margin >60° demonstrated in typical performance curves.
How does the channel-to-channel matching of LT6204CS#PBF benefit multi-amplifier designs?
LT6204CS#PBF provides tight channel-to-channel matching: 0.15mV typical input offset voltage match (A–D and B–C pairs), 83dB typical CMRR match, and 70dB typical PSRR match. This enables precise differential signal processing - such as in 3-op-amp instrumentation amplifiers or matched gain blocks - without calibration, reducing system-level drift and improving common-mode rejection in noisy environments.
