Product details
Overview
LT6204IGN#PBF 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, and is specified over –40°C to +85°C for industrial signal conditioning in precision data acquisition and A/D driver applications.
For engineers reviewing the LT6204IGN#PBF datasheet, LT6204IGN#PBF pinout, LT6204IGN#PBF application, or LT6204IGN#PBF equivalent, key selection criteria include its rail-to-rail output swing (within 25mV of rails at 5mA), low distortion (–80dBc at 1MHz), and guaranteed performance across ±5V, +5V, and +3V supplies - critical for battery-powered instrumentation and high-fidelity analog front-ends.
Technical Context
The LT6204IGN#PBF implements a unity-gain-stable voltage-feedback architecture optimized for low-supply, low-noise signal chains. Its input stage supports common-mode voltages extending to both supply rails, and its output delivers ±30mA drive capability into resistive loads while maintaining <0.1% settling in 85ns.
It features matched channel-to-channel parameters including input offset voltage match ≤0.3mV (typ), CMRR match ≥80dB, and PSRR match ≥70dB - enabling precise differential amplification and active filter topologies where amplifier pairing matters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Noise Voltage Density | 1.9nV/√Hz at 100kHz - enables sub-μV signal resolution in sensor interfaces without added gain-stage noise penalty |
| Gain Bandwidth Product | 100MHz - supports stable closed-loop operation up to 10MHz at G=10, suitable for wideband active filters and video buffers |
| Slew Rate | 25V/µs - ensures faithful reproduction of fast transients (e.g., 10V step in <400ns) in pulse-amplifier and DAC output stages |
| Supply Current per Amp | 2.5mA max at 5V - allows four independent channels in <10mA total, ideal for space-constrained portable systems |
| Input Common-Mode Range | Rail-to-rail - accepts signals from V– to V+, eliminating level-shifting needs in single-supply 3.3V/5V systems |
| Output Swing | Within 25mV of rails at 5mA - maximizes dynamic range when driving SAR ADCs with 0–VREF inputs |
| Harmonic Distortion | –80dBc at 1MHz - meets SNR requirements for 14-bit+ data acquisition at medium frequencies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-noise op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8604ARUZ | Lower noise (1.3nV/√Hz), lower GBW (8MHz), higher supply current (1.3mA/amp), SOIC-14 package only | Better for DC-precision, low-bandwidth apps (e.g., pH meters); unsuitable for >1MHz filtering or fast settling | Select AD8604ARUZ when ultra-low DC drift and offset dominate over speed and noise at RF frequencies |
| OPA211AIDGKR | Lower noise (1.1nV/√Hz), higher GBW (45MHz), higher supply current (3.6mA/amp), DFN-8 (dual only), no quad variant | Superior noise/precision for dual-channel apps; requires two devices + extra PCB area for quad functionality | Choose OPA211AIDGKR for highest SNR in dual-channel precision systems where board space allows dual placement |
Compared with AD8604ARUZ and OPA211AIDGKR, LT6204IGN#PBF uniquely balances 100MHz bandwidth, 1.9nV/√Hz noise, and true quad integration in SSOP - making it optimal for space-constrained, wideband, multichannel signal chains where channel matching and supply flexibility matter.

FAQ
What is the operating temperature range for LT6204IGN#PBF?
The LT6204IGN#PBF is rated for operation from –40°C to +85°C and is tested and guaranteed across this full industrial temperature range. This specification is explicitly defined in the Absolute Maximum Ratings and Electrical Characteristics tables of the official datasheet, with performance validated at multiple temperatures including TA = –40°C, 25°C, and +85°C under ±5V and +5V supplies.
Does LT6204IGN#PBF support single-supply operation?
Yes, LT6204IGN#PBF supports true single-supply operation from 2.5V to 12.6V. Its rail-to-rail input common-mode range extends from V– to V+, and its output swings within 25mV of both rails at 5mA load - enabling direct interfacing with 3.3V or 5V microcontrollers and ADCs without level-shifting circuitry.
What is the maximum output current capability of LT6204IGN#PBF?
Each amplifier in the LT6204IGN#PBF can source and sink ≥30mA continuously (±30mA short-circuit current, indefinite duration). This is confirmed in the Absolute Maximum Ratings table and verified across temperature and supply conditions - supporting direct driving of moderate-impedance loads such as 100Ω cables or ADC input capacitors without external buffers.
Is LT6204IGN#PBF unity-gain stable?
Yes, LT6204IGN#PBF is explicitly designed and characterized for unity-gain stability. The datasheet states "unity gain stable" as a core feature, and all typical performance curves (e.g., small-signal step response, open-loop gain vs frequency) are measured under G = +1 configuration - confirming unconditional stability without external compensation.
How does LT6204IGN#PBF compare to LT6204CGN#PBF?
LT6204IGN#PBF and LT6204CGN#PBF share identical electrical specifications and GN-package pinout, differing only in temperature grade: IGN denotes –40°C to +85°C industrial qualification, while CGN specifies 0°C to +70°C commercial grade. Both use the same die and assembly process; the IGN variant undergoes extended temperature testing and screening per industrial reliability standards.
