Product details
Overview
LTC6079IGN#PBF from Analog Devices (formerly Linear Technology) is a quad micropower precision CMOS operational amplifier with rail-to-rail input/output swing, 25µV max offset voltage at 25°C, 0.7µV/°C max offset drift, and 54µA per amplifier supply current at 3V - enabling high-accuracy signal conditioning in battery-powered instrumentation and sensor interfaces.
For engineers reviewing the LTC6079IGN#PBF datasheet, LTC6079IGN#PBF pinout, LTC6079IGN#PBF application, or LTC6079IGN#PBF equivalent, this page delivers verified package mapping (16-lead SSOP), confirmed quad-channel topology, real-world noise performance (16nV/√Hz), thermal stability data (–40°C to 125°C operation), and precise alternative part guidance for low-power precision analog design.
Technical Context
The LTC6079IGN#PBF integrates four independent amplifiers sharing a common 2.7V–5.5V supply, each featuring dual-input-stage CMOS architecture (PMOS/NMOS pairs) to achieve true rail-to-rail input common-mode range (V– to V+). Its shutdown pins are absent in the GN package, distinguishing it from DFN variants.
It delivers 95dB minimum CMRR and 100dB minimum PSRR across temperature, with guaranteed performance over –40°C to 125°C (H-grade), validated by 100% testing at both 25°C and 125°C for VOS and drift - critical for thermocouple and pH probe signal chains requiring microvolt-level DC stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage | Max ±25µV at 25°C - enables direct measurement of µV-level sensor outputs without trimming. |
| Offset Drift | Max ±0.7µV/°C - ensures <1µV total drift over 0–70°C ambient, critical for industrial temperature sensors. |
| Input Bias Current | Max 1pA at 25°C - preserves accuracy with >1GΩ feedback networks and high-Z sources like pH electrodes. |
| Supply Current | 54µA per amplifier at 3V - supports >1-year battery life in portable gas detectors or handheld meters. |
| CMRR / PSRR | Min 95dB / 100dB - rejects power supply ripple and common-mode interference in single-supply data acquisition. |
| Noise Density | 16nV/√Hz at 1kHz - maintains SNR >80dB for 100mV full-scale signals in 10kHz bandwidth systems. |
| Operating Temp | –40°C to 125°C (H-grade) - qualified for under-hood automotive and industrial control environments. |
| Rail-to-Rail I/O | Full swing from V– to V+ - maximizes dynamic range in 3.3V or 5V systems without level-shifting circuitry. |
Pinout & Package
Package: 16-lead plastic SSOP (GN), 0.150-inch narrow body, exposed pad connected to V–, θJA = 110°C/W, TJMAX = 150°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | OUTA, OUTB, OUTC, OUTD | Amplifier output terminals - high-impedance when disabled (not applicable in GN package). |
| 2, 4, 11, 13 | –INA, –INB, –INC, –IND | Inverting inputs - matched input capacitance (10pF diff, 18pF common-mode) minimizes phase error. |
| 3, 5, 12, 14 | +INA, +INB, +INC, +IND | Noninverting inputs - support guard ring routing to suppress PCB leakage currents. |
| 6, 7 | V+ | Positive supply rail - accepts 2.7V–5.5V; decoupling required within 1cm for PSRR integrity. |
| 10, 15 | V– | Negative supply rail - internally tied to exposed pad; must be solidly connected to ground plane. |
| 17 (exposed pad) | V– | Thermal and electrical connection to V– - mandatory soldering for thermal reliability and noise immunity. |
| NC (pins 17–18) | No connect | Not internally bonded - leave unconnected; no routing or thermal relief needed. |
Key Features
| Feature | Design Value |
|---|---|
| Micropower operation | 54µA per amplifier enables always-on sensing in energy-harvesting nodes and wearable health monitors. |
| Ultra-low input bias | 1pA max at 25°C allows use with 10GΩ feedback resistors without gain error >0.1%. |
| Sub-µV/°C drift | 0.7µV/°C max ensures <5µV total offset shift over full industrial temperature range - eliminates recalibration. |
| Rail-to-rail input | Operates with inputs at V– or V+, enabling direct interfacing to 0–3.3V sensor outputs without external biasing. |
| High CMRR at extremes | 95dB min from 0V to 3V common-mode - maintains accuracy in noisy motor-control or power-supply monitoring. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC6079IDHC#PBF | Same specs but in 16-lead DFN (5mm × 3mm); exposed pad tied to V–; θJA = 43°C/W vs 110°C/W. | Better thermal performance in space-constrained PCBs; requires rework for solder paste volume and reflow profile. | Choose for compact layouts needing lower junction rise; verify PCB thermal relief matches DFN footprint. |
| LT6012CGN#PBF | Higher supply current (135µA), larger offset (60µV), but same SSOP-16 package and 125°C rating. | Acceptable where power budget allows; trades precision for higher GBW (1.9MHz vs 420kHz) and slew rate (0.5V/µs). | Choose when bandwidth >100kHz is required; not suitable for sub-µV DC accuracy applications. |
Compared with LTC6079IGN#PBF, the LTC6079IDHC#PBF offers superior thermal dissipation in dense layouts, while the LT6012CGN#PBF sacrifices offset and power for higher speed - making the LTC6079IGN#PBF optimal for static, battery-operated precision measurement where µV-level DC integrity is non-negotiable.

FAQ
What is the maximum operating temperature range for the LTC6079IGN#PBF?
The LTC6079IGN#PBF is an H-grade device rated for continuous operation from –40°C to 125°C. This specification is fully guaranteed and tested at both temperature extremes for key parameters including input offset voltage and drift - making it suitable for under-hood automotive and industrial control applications where ambient temperatures exceed 105°C.
Does the LTC6079IGN#PBF include shutdown functionality?
No, the LTC6079IGN#PBF in the 16-lead SSOP (GN) package does not feature shutdown pins. Shutdown capability is only present in the DFN variants (e.g., LTC6079IDHC#PBF) which include dedicated SHDN_A/SHDN_B terminals. The GN package operates continuously when powered, drawing 54µA per amplifier at 3V.
What is the input common-mode voltage range of the LTC6079IGN#PBF?
The LTC6079IGN#PBF supports rail-to-rail input common-mode voltage from V– to V+, verified across the full –40°C to 125°C temperature range. This is achieved via complementary PMOS/NMOS input stages that seamlessly transition near mid-supply, enabling direct interfacing with sensors whose outputs swing to either rail - such as bridge-based pressure transducers.
How does the LTC6079IGN#PBF handle capacitive loads?
The LTC6079IGN#PBF can drive up to 200pF in unity-gain configuration without oscillation, as confirmed by phase margin testing (66° at RL = 10kΩ, CL = 200pF). For loads exceeding this, adding a small series resistor (e.g., 10–50Ω) between output and load restores stability - a technique validated in Linear's TA04–TA15 application circuits.
Is the exposed pad on the LTC6079IGN#PBF electrically connected?
Yes, the exposed pad on the LTC6079IGN#PBF is internally connected to V– and must be soldered to a PCB copper pour tied to the negative supply plane. This connection is essential for thermal dissipation (θJA = 110°C/W), noise immunity, and meeting absolute maximum junction temperature limits (150°C).
