Product details
Overview
LT6204IS#TRPBF from Analog Devices (formerly Linear Technology) is a quad rail-to-rail input/output ultralow-noise operational amplifier with 1.9nV/√Hz input voltage noise, 100MHz gain bandwidth product, and 25V/µs slew rate. It operates from 2.5V to 12.6V supply, draws 2.5mA per amplifier at 5V, and is specified for –40°C to +85°C industrial temperature range - ideal for precision signal conditioning in DSL receivers and battery-powered data acquisition systems.
For engineers reviewing the LT6204IS#TRPBF datasheet, LT6204IS#TRPBF pinout, LT6204IS#TRPBF application, or LT6204IS#TRPBF equivalent, key selection criteria include its guaranteed rail-to-rail output swing into 100Ω loads, channel-to-channel matching of offset voltage (<1.0mV), low distortion (–80dBc at 1MHz), and compatibility with ±5V or single 3V–12.6V supplies in space-constrained 14-pin SO layouts.
Technical Context
The LT6204IS#TRPBF integrates four independent unity-gain-stable amplifiers optimized for low-noise, low-power signal chains. Its input stage uses complementary bipolar architecture enabling rail-to-rail common-mode input range and 1.9nV/√Hz noise density at 100kHz, while the output stage delivers ±30mA drive capability with <250mV saturation voltage at 15mA sink/source under 5V supply.
It maintains stable operation across wide supply voltages (2.5V–12.6V) and exhibits robust AC performance: 100MHz GBW, 25V/µs slew rate, and full-power bandwidth of 2.5MHz (3VP-P output). Harmonic distortion remains below –80dBc at 1MHz, supporting high-fidelity analog front-ends in communications and instrumentation.

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 |
|---|---|---|---|
| LT6204CS#TRPBF | Same quad architecture and pinout, but rated for 0°C to 70°C commercial temperature range | Not suitable for extended industrial environments requiring –40°C startup or 85°C sustained operation | Select LT6204IS#TRPBF when ambient operating temperature exceeds 70°C or must guarantee performance over full industrial range |
| ADA4897-2ARZ-R7 | Dual-channel, lower noise (1.0nV/√Hz), higher supply current (3.6mA/amp), 225MHz GBW, MSOP-8 package | Lacks quad integration; requires two devices for four channels - increases board area and component count | Choose ADA4897-2ARZ-R7 only when ultra-low noise and higher speed outweigh channel density and power efficiency needs |
Compared with LT6204CS#TRPBF, the LT6204IS#TRPBF provides guaranteed –40°C to +85°C operation essential for outdoor or factory-floor deployments; versus ADA4897-2ARZ-R7, it offers integrated quad functionality at lower total power and smaller PCB footprint despite slightly higher noise.

FAQ
What is the maximum supply voltage rating for LT6204IS#TRPBF?
The absolute maximum total supply voltage (V+ to V–) for LT6204IS#TRPBF is 12.6V. Operation beyond this limit 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 - making LT6204IS#TRPBF suitable for both low-voltage portable systems and higher-voltage industrial rails.
Does LT6204IS#TRPBF support true rail-to-rail input and output operation?
Yes, LT6204IS#TRPBF features rail-to-rail input common-mode range (V– to V+) and rail-to-rail output swing. At 5V supply with 15mA load, output voltage saturates within 250mV of each rail - delivering >4.5VPP usable swing. Input stage accepts signals at either supply rail without phase reversal or increased bias current, enabling direct interfacing with ADCs and DACs in single-supply configurations.
What is the typical input offset voltage for LT6204IS#TRPBF at 25°C and 5V supply?
At TA = 25°C and VS = 5V, the typical input offset voltage for LT6204IS#TRPBF is 0.2mV when VCM = half supply, and 1.0mV when VCM spans V– to V+. Over the full –40°C to +85°C industrial temperature range, max offset is 3.5mV (VCM = V– to V+), with typical drift of 3.0µV/°C - ensuring stable DC accuracy in precision sensor amplification stages using LT6204IS#TRPBF.
Can LT6204IS#TRPBF drive a 100Ω load effectively?
Yes, LT6204IS#TRPBF delivers ±30mA output current and maintains rail-to-rail swing into 100Ω loads. At 5V supply, output voltage remains within 360mV of V+ and 460mV of V– at 20mA source/sink - enabling direct driving of coaxial cables, ADC reference buffers, or low-impedance active filters without external boost stages. This capability is explicitly verified in the datasheet's VOL/VOH specifications under ISOURCE/ISINK conditions.
Is LT6204IS#TRPBF pin-compatible with other members of the LT620x family?
LT6204IS#TRPBF is pin-compatible with LT6204CS#TRPBF (commercial temp) and LT6204IGN#TRPBF (SSOP package), sharing identical 14-pin SO pinout. However, it is not pin-compatible with dual LT6203 or single LT6202 variants due to differing channel count and pin assignments. Always verify package-specific pin diagrams - e.g., LT6204IS#TRPBF uses 14-pin SO (S package), while LT6204IGN#TRPBF uses 16-pin SSOP (GN package) - before PCB layout.
