Product details
Overview
LTC6082IGN#PBF from Analog Devices (formerly Linear Technology) is a quad precision CMOS rail-to-rail input/output operational amplifier optimized for microvolt-level signal conditioning in high-impedance sensor interfaces. It delivers 70µV max offset voltage, 0.8µV/°C max offset drift, 1pA max input bias current at 25°C, 1.3µVP-P 0.1Hz–10Hz noise, and 100dB min CMRR - enabling accurate thermocouple, strain gauge, and photodiode amplification across –40°C to 85°C.
For engineers reviewing the LTC6082IGN#PBF datasheet, LTC6082IGN#PBF pinout, LTC6082IGN#PBF application, or LTC6082IGN#PBF equivalent, this page provides verified package mapping (16-lead SSOP), confirmed shutdown functionality per amplifier, rail-to-rail I/O behavior under 2.7V–5.5V supply, and real-world design implications of its 3.6MHz GBW and 330µA/amplifier quiescent current.
Technical Context
The LTC6082IGN#PBF integrates four independent precision op-amps sharing a common 2.7V–5.5V supply, each featuring dual-input-stage architecture (PMOS + NMOS differential pairs) to achieve true rail-to-rail input common-mode range (V– to V+). Its 120dB typical open-loop gain and 100dB minimum CMRR ensure stable closed-loop performance in instrumentation-grade configurations.
Each amplifier includes independent output stage control with 1VOL/1VOH swing capability into 5mA loads, 1V/µs slew rate, and unity-gain stability. The GN package variant lacks dedicated SHDN pins - shutdown is not implemented in the SSOP configuration, unlike the DFN variants.
Key Specifications

|---|---|
| Offset Voltage | 70µV max at 25°C - enables sub-millivolt accuracy in DC-coupled sensor front-ends without trimming. |
| Offset Drift | 0.8µV/°C max - limits thermal-induced error to ≤6.4µV over 80°C ambient shift. |
| Input Bias Current | 1pA max at 25°C - preserves signal integrity with >1GΩ source impedances (e.g., piezoelectric sensors). |
| 0.1Hz–10Hz Noise | 1.3µVP-P - supports µV-level threshold detection in low-frequency industrial monitoring. |
| Gain-Bandwidth Product | 3.6MHz - allows stable 10× gain up to 360kHz or 100× gain up to 36kHz for precision filtering. |
| CMRR | 100dB min - rejects common-mode interference in noisy industrial environments (e.g., motor drives). |
| Supply Current | 330µA per amplifier - enables battery-powered portable instrumentation with four-channel analog front-end. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - rail-to-rail swing, capable of sourcing/sinking 5mA. |
| 2 | –INA | Inverting input of Amp A - high-impedance node requiring guard ring in PCB layout. |
| 3 | +INA | Noninverting input of Amp A - matched to –INA for optimal CMRR performance. |
| 4 | V+ | Positive supply rail - accepts 2.7V–5.5V; bypass capacitor required near pin. |
| 5 | +INB | Noninverting input of Amp B - electrically isolated from other inputs; no internal connection to Amp A. |
| 6 | –INB | Inverting input of Amp B - same layout rules apply as for –INA. |
| 7 | OUTB | Amplifier B output - independent drive capability; no crosstalk with OUTA beyond –120dB channel separation. |
| 8 | NC | No internal connection - must be left unconnected; not used for thermal relief or grounding. |
| 9 | OUTD | Amplifier D output - fourth channel; identical specs and drive strength as OUTA/B/C. |
| 10 | –IND | Inverting input of Amp D - matches –INA/–INB/–INC in bias current and capacitance (3pF diff, 7pF common-mode). |
| 11 | +IND | Noninverting input of Amp D - symmetric layout critical for matching across all four channels. |
| 12 | V– | Negative supply rail - connected internally to exposed pad; primary return path for all amplifiers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2052IGN#PBF | Zero-drift architecture; 0.015µV/°C max drift vs. 0.8µV/°C; higher 1.5µVP-P noise; 500µA/amplifier supply current. | Better long-term DC stability but higher noise and power - preferred for ultra-stable DC offsets over years, not low-noise AC signals. | Select LTC2052IGN#PBF when drift dominates error budget and noise is secondary; LTC6082IGN#PBF when low noise and low power are prioritized. |
| OPA2189IDR | Single-supply, rail-to-rail I/O; 4µV max offset; 0.005µV/°C drift; 5.2nV/√Hz wideband noise; 1.3mA/amplifier supply current. | Lower offset and drift, but higher noise density and 4× higher supply current - suited for high-speed precision, not low-power µV sensing. | Choose OPA2189IDR for applications needing sub-µV offset and fast settling; LTC6082IGN#PBF where 330µA/quiescent current and 1.3µVP-P low-frequency noise are mandatory. |
Compared with LTC2052IGN#PBF and OPA2189IDR, LTC6082IGN#PBF uniquely balances ultra-low input bias (1pA), low 0.1Hz–10Hz noise (1.3µVP-P), and low quiescent current (330µA) - making it optimal for battery-powered, high-impedance, low-frequency sensor systems where zero-drift isn't required but microamp-level power and femtoamp-level leakage matter.

FAQ
What is the operating temperature range for LTC6082IGN#PBF?
The LTC6082IGN#PBF is specified for operation from –40°C to +85°C, with guaranteed performance across this full industrial temperature range. Its maximum offset voltage remains ≤70µV and input bias current ≤1pA at 25°C, while drift is bounded at ±0.8µV/°C - ensuring predictable behavior in outdoor or factory-floor environments.
Does LTC6082IGN#PBF support shutdown functionality?
No, the LTC6082IGN#PBF in the 16-lead SSOP (GN) package does not include shutdown pins. Shutdown capability is only available in the DFN variants (e.g., LTC6082IDHC#PBF), which feature dedicated SHDN_A through SHDN_D pins. The GN package uses all 16 pins for signal I/O and power, with no provision for individual amplifier disable.
What is the input common-mode voltage range of LTC6082IGN#PBF?
The LTC6082IGN#PBF supports a true rail-to-rail input common-mode voltage range from V– to V+, verified across its full supply range (2.7V to 5.5V). This is achieved via complementary PMOS/NMOS input stages that auto-switch based on VCM, enabling accurate amplification of signals near either supply rail - critical for single-supply sensor interfaces.
Can LTC6082IGN#PBF drive capacitive loads?
Yes, the LTC6082IGN#PBF can drive up to 200pF in unity-gain configuration while maintaining stability, as confirmed by phase margin measurements ≥70°. For larger capacitive loads or higher gains, adding a small series resistor (e.g., 10–50Ω) between output and load improves phase margin and reduces overshoot - a technique validated in the datasheet's "Capacitive Load" section.
How does the noise performance of LTC6082IGN#PBF compare between 3V and 5V supply?
The LTC6082IGN#PBF exhibits identical 0.1Hz–10Hz input-referred noise (1.3µVP-P) and 1kHz noise density (13nV/√Hz) at both 3V and 5V supplies. Its low-noise architecture is supply-independent in this range, allowing designers to select voltage based on system headroom or power constraints without degrading signal-to-noise ratio in precision DC or low-frequency AC applications.
