Product details
Overview
LT6204CS#TRPBF from Analog Devices (formerly Linear Technology) is a quad rail-to-rail input/output operational amplifier optimized for low-noise, low-power signal conditioning in precision analog front-ends. 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 supply - enabling high-fidelity amplification in battery-powered data acquisition and DSL receiver circuits.
For engineers reviewing the LT6204CS#TRPBF datasheet, LT6204CS#TRPBF pinout, LT6204CS#TRPBF application, or LT6204CS#TRPBF equivalent, key selection criteria include its guaranteed 0°C to 70°C operating range, 14-pin SO package with standard dual-op-amp-compatible pinout per channel, rail-to-rail output swing within 260mV of rails at 15mA load, and ±30mA short-circuit output current capability.
Technical Context
The LT6204CS#TRPBF implements a unity-gain-stable voltage-feedback architecture with fully differential input stage and Class AB output stage. Its input common-mode range extends from V– to V+, and output swings rail-to-rail under moderate loads - critical for maximizing dynamic range in single-supply systems.
It maintains 90dB typical CMRR and 74dB PSRR across 2.5V–12.6V supply range, with harmonic distortion below –80dBc at 1MHz. The quad configuration shares thermal coupling benefits for matched-channel applications like instrumentation amplifiers and active filters.

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 |
|---|---|---|---|
| OPA2188AIDR | Lower offset (25µV max), higher precision, but 6.5MHz GBW and 2.2nV/√Hz noise - trades speed/noise for DC accuracy | Better for µV-level DC-coupled sensor interfaces; unsuitable for >1MHz signal paths requiring 100MHz GBW | Select when offset drift (<0.003µV/°C) and long-term stability outweigh bandwidth needs |
| ADA4898-2ARZ | Higher speed (270MHz GBW), lower noise (1.1nV/√Hz), but 10mA/amp supply current and ±5V-only supply - not single-supply compatible | Preferred for high-speed photodiode transimpedance or RF IF amplification; incompatible with 3.3V battery systems | Select when >100MHz small-signal bandwidth and sub-1.2nV/√Hz noise justify 4× higher power draw and dual-supply requirement |
Compared with OPA2188AIDR and ADA4898-2ARZ, the LT6204CS#TRPBF uniquely balances 100MHz bandwidth, 1.9nV/√Hz noise, and 2.5mA/amp power in a 14-pin SO package - making it optimal for cost-sensitive, battery-operated, wideband analog front-ends where neither ultra-low offset nor extreme speed dominates.

FAQ
What is the maximum supply voltage rating for the LT6204CS#TRPBF?
The LT6204CS#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 performance, Analog Devices specifies operation from 2.5V to 12.6V, with full parametric guarantees at 3V, 5V, and ±5V supplies. The LT6204CS#TRPBF maintains rail-to-rail input/output functionality across this entire range.
Does the LT6204CS#TRPBF support true rail-to-rail input common-mode range?
Yes, the LT6204CS#TRPBF supports input common-mode voltage from V– to V+, inclusive. This is confirmed in the datasheet's "Features" section and verified in Electrical Characteristics tables under conditions where VCM = V+ to V–. At 5V supply, this means the input accepts signals from 0V to 5V without phase reversal or increased distortion - a key enabler for single-supply sensor interfaces. The LT6204CS#TRPBF achieves this via complementary differential input pairs.
What is the typical output drive capability of the LT6204CS#TRPBF?
The LT6204CS#TRPBF delivers ±30mA minimum short-circuit output current and sustains rail-to-rail swing into 1kΩ loads. At 15mA sink/source, output saturation remains within 260mV of either rail at 5V supply - verified in the "ELECTRICAL CHARACTERISTICS" table under VOL/VOH conditions. This drive strength supports direct interfacing to ADC inputs, transmission lines, and moderate-current active filters without external buffers. The LT6204CS#TRPBF maintains stability with capacitive loads up to 100pF.
How does the LT6204CS#TRPBF perform in terms of harmonic distortion at 1MHz?
The LT6204CS#TRPBF exhibits harmonic distortion less than –80dBc at 1MHz, as specified in the "Features" list and confirmed in the "ELECTRICAL CHARACTERISTICS" table under "Low Distortion" parameter. This performance holds for unity-gain and higher closed-loop configurations with proper PCB layout and supply decoupling. Such low distortion makes the LT6204CS#TRPBF suitable for DSL receiver IF stages and medical signal chains where spectral purity directly impacts measurement fidelity.
Is the LT6204CS#TRPBF pin-compatible with standard dual op amp SO packages?
The LT6204CS#TRPBF uses a 14-pin SO package with pinout aligned to industry-standard dual op amp layouts for channels A/B (Pins 1–7) and extended mapping for channels C/D (Pins 8–14). While not drop-in compatible with dual op amps due to quad integration, its per-channel pin assignment (e.g., +IN/–IN/OUT per amplifier) follows conventional SO conventions - simplifying layout reuse in multi-channel designs. The LT6204CS#TRPBF datasheet explicitly confirms this mapping in the "PIN CONFIGURATION" diagram for the S package.
