Product details
Overview
LTC6078IDD#PBF from Analog Devices (formerly Linear Technology) is a dual 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 LTC6078IDD#PBF datasheet, LTC6078IDD#PBF pinout, LTC6078IDD#PBF application, or LTC6078IDD#PBF equivalent, this page delivers verified package mapping (10-lead DFN), shutdown-capable dual-channel architecture, thermally stable VOS performance across –40°C to 125°C, and design-critical parameters including 95dB min CMRR, 16nV/√Hz input noise density, and ±1pA input bias at 25°C.
Technical Context
The LTC6078IDD#PBF integrates two independent amplifiers sharing a common 2.7V–5.5V supply, each featuring complementary PMOS/NMOS input stages for true rail-to-rail common-mode range (V– to V+), internal offset trimming, and active low shutdown pins (SHDN_A/SHDN_B) that reduce quiescent current to ≤1µA per channel. Its architecture targets DC-critical applications where thermal hysteresis (<1µV after three cycles) and long-term VOS stability under differential stress are essential.
It operates across –40°C to 125°C (H-grade), supports capacitive loads up to 200pF in unity gain, and maintains 115dB large-signal voltage gain with 420kHz gain-bandwidth product - all while delivering 100dB PSRR and 95dB CMRR over full common-mode range, making it suitable for high-impedance, low-power front-end stages in precision analog systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 5.5V - enables direct operation from single Li-ion or 3.3V/5V rails without regulation overhead |
| Max Input Offset Voltage | 25µV at 25°C - ensures sub-100µV system-level error in mV-range sensor outputs without calibration |
| Max Offset Drift | 0.7µV/°C - limits temperature-induced error to <84µV over 120°C industrial range |
| Supply Current per Amp | 54µA at 3V - allows dual-channel operation below 110µA total, critical for multi-year battery life |
| Input Bias Current | 1pA at 25°C - preserves accuracy with >1GΩ feedback networks and high-Z sensors like pH probes |
| CMRR / PSRR | 95dB / 100dB min - rejects power supply ripple and common-mode interference in noisy environments |
| Input Noise Density | 16nV/√Hz at 1kHz - supports low-noise amplification of µV-level thermocouple or photodiode signals |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs or downstream stages without level-shifting |
Pinout & Package
10-lead (3mm × 3mm) plastic DFN package with exposed metal pad connected to V–; thermal resistance θJA = 43°C/W; junction temperature limit 125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive Supply | Connects to main supply rail (2.7V–5.5V); powers both amplifiers and shutdown logic |
| OUTB | Amplifier B Output | High-impedance during SHDN_B assert; rail-to-rail swing supports direct ADC interfacing |
| –INB | Inverting Input B | Low-bias node (1pA typ) - requires guard ring layout for leakage-sensitive applications |
| +INB | Noninverting Input B | Matches –INB characteristics; differential pair transitions smoothly across rail extremes |

| –INA | Inverting Input A | Electrically identical to –INB; validated for photodiode transimpedance configurations |
| +INA | Noninverting Input A | Used in reference buffer or high-Z sensor follower topologies with minimal loading |
| V– | Negative Supply | Reference for all inputs/outputs; exposed pad must be soldered to PCB ground plane for thermal/EMI control |
| SHDN_A | Shutdown A (active low) | Enables independent power gating per channel - critical for duty-cycled sensor nodes |
Key Features
| Feature | Design Value |
|---|---|
| Micropower Operation | 54µA per amplifier at 3V enables dual-channel precision amplification within 110µA total budget |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC6078IMS8#PBF | Same core specs but in 8-lead MSOP; higher θJA (200°C/W) and 150°C junction limit vs. DFN's 125°C | Preferred for prototyping or low-volume boards where hand-soldering is required; less suitable for thermally constrained layouts | Select when thermal management via heatsinking is feasible and DFN reflow is unavailable |
| ADA4522-2ARZ | Zero-drift architecture (3µV VOS, 30nV/°C drift); higher supply current (135µA/amp) and wider supply range (4.5–36V) | Better for ultra-stable DC offsets over temperature; unsuitable for sub-3V battery operation due to 4.5V minimum supply | Choose only when sub-5µV offset stability outweighs 2.5× higher current and voltage compliance constraints |
Compared with LTC6078IMS8#PBF, the LTC6078IDD#PBF offers superior thermal performance (43°C/W vs. 200°C/W) and smaller footprint for space-constrained designs, while ADA4522-2ARZ trades micropower efficiency for near-zero drift - making LTC6078IDD#PBF optimal for battery-operated precision analog front-ends where <110µA total current and 3V compatibility are mandatory.

FAQ
What is the maximum operating temperature range for the LTC6078IDD#PBF?
The LTC6078IDD#PBF is rated for operation from –40°C to 125°C (H-grade), with guaranteed parametric performance across this full range. Its DFN package has a maximum junction temperature of 125°C and thermal resistance θJA = 43°C/W, requiring appropriate PCB copper area for heat dissipation in high-ambient environments. The LTC6078IDD#PBF meets industrial and automotive under-hood temperature requirements when properly mounted.
Does the LTC6078IDD#PBF support rail-to-rail input and output simultaneously?
Yes, the LTC6078IDD#PBF supports true rail-to-rail input common-mode range (V– to V+) and rail-to-rail output swing (within 1mV of either rail under light load). This is achieved via complementary PMOS/NMOS input pairs and optimized output stage design. At VCM = V+/2, CMRR remains ≥95dB, and output can source/sink 0.2mA while staying within 35mV of the rails - enabling direct interfacing with 3.3V ADCs and low-voltage logic without external level shifters.
How does the shutdown functionality work on the LTC6078IDD#PBF?
The LTC6078IDD#PBF features two independent active-low shutdown pins: SHDN_A (Pin 9) and SHDN_B (Pin 5). When pulled ≤0.8V, each pin disables its respective amplifier, reducing supply current to ≤1µA per channel while placing the output in high-impedance state. Internal pull-up current sources drive both pins to V+ when floating, ensuring normal operation by default. Turn-on time is 50µs; turn-off time is 2µs - supporting rapid duty-cycled operation in energy-constrained systems using the LTC6078IDD#PBF.
What is the typical input bias current of the LTC6078IDD#PBF at 85°C?
The LTC6078IDD#PBF specifies a maximum input bias current of 50pA at temperatures ≤85°C, with typical performance at 10pA. This value is guaranteed by testing at VS = 5V and reflects the CMOS input stage's thermal behavior. At 25°C, typical IB is 0.2pA, rising gradually with temperature - remaining well below 100pA even at 125°C. This stability makes the LTC6078IDD#PBF suitable for high-impedance sensor buffering where leakage currents must stay below 100pA across full operating range.
Can the LTC6078IDD#PBF drive capacitive loads, and what is the limit?
Yes, the LTC6078IDD#PBF can drive capacitive loads up to 200pF in unity-gain configuration while maintaining stability, as confirmed by phase margin measurements (66°) and transient response testing. For loads >200pF, adding a small series resistor (e.g., 10–50Ω) between the output and capacitor improves phase margin. The device's ability to drive capacitance increases with closed-loop gain - at AV = 10, it supports >1nF loads. This capability is critical for driving ADC input capacitors or long PCB traces in sensor interface designs using the LTC6078IDD#PBF.
