Product details
Overview
LTC6078HMS8#TRPBF from Analog Devices (acquired Linear Technology) is a dual, micropower, precision rail-to-rail input/output operational amplifier optimized for high-impedance sensor interfaces and battery-powered instrumentation. It delivers 25µV max offset voltage, 0.7µV/°C max offset drift, 54µA per amplifier supply current at 3V, 95dB min CMRR, and operates from –40°C to 125°C in the 8-lead MSOP package.
For engineers reviewing the LTC6078HMS8#TRPBF datasheet, LTC6078HMS8#TRPBF pinout, LTC6078HMS8#TRPBF application, or LTC6078HMS8#TRPBF equivalent, this page provides verified specifications, thermal-grade packaging details, real-world signal conditioning use cases, and validated alternative options for precision analog design.
Technical Context
The LTC6078HMS8#TRPBF integrates complementary PMOS/NMOS input stages to achieve true rail-to-rail common-mode input range (V– to V+), enabling direct interfacing with low-voltage sensors and single-supply systems. Its micropower architecture maintains precision performance-sub-1pA typical input bias current at 25°C and ≤50pA up to 85°C-without compromising DC accuracy.
It features active shutdown control (SHDN_A/SHDN_B pins only in DFN variant; not present in MS8 package), 16nV/√Hz input voltage noise density at 1kHz, and stable unity-gain operation into capacitive loads up to 200pF-critical for photodiode and pH probe front-ends requiring minimal signal degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 5.5V - supports direct integration into Li-ion, coin-cell, and industrial 3.3V/5V systems without level-shifting. |
| Input Offset Voltage (Max) | 25µV at 25°C - enables microvolt-level threshold detection and thermocouple signal conditioning without trimming. |
| Offset Drift (Max) | 0.7µV/°C - ensures stable DC gain over full –40°C to 125°C operating range, critical for automotive and industrial environments. |
| Supply Current (Per Amp) | 54µA at 3V - allows dual-channel precision amplification in ultra-low-power applications like portable gas analyzers or wearable biosensors. |
| CMRR (Min) | 95dB - rejects common-mode noise from noisy PCB traces or shared power rails in high-resolution data acquisition. |
| Input Bias Current (Max) | 50pA ≤85°C - preserves accuracy with >1GΩ feedback networks and high-Z sources such as pH electrodes or piezoresistive sensors. |
| Rail-to-Rail I/O | Fully supported - maximizes dynamic range in single-supply configurations, e.g., 0–3.3V ADC input scaling without headroom loss. |
Pinout & Package
Package: 8-lead plastic MSOP (MS8), 3mm × 3mm body, exposed pad connected to V–, rated for 150°C junction temperature (θJA = 200°C/W).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - drives low-impedance loads or feeds next-stage filtering; rail-to-rail swing supports full supply utilization. |
| 2 | –INA | Inverting input of Amplifier A - high-impedance node; requires guard ring routing to prevent leakage-induced offset errors. |
| 3 | +INA | Noninverting input of Amplifier A - accepts signals from high-Z sources (e.g., thermistors, photodiodes) with sub-picoampere bias error. |
| 4 | V– | Negative supply rail - also connects to exposed thermal pad; must be low-impedance ground plane for thermal stability and noise rejection. |
| 5 | V+ | Positive supply rail - decoupling capacitor (0.1µF ceramic) required within 2mm for PSRR optimization above 10kHz. |
| 6 | OUTB | Amplifier B output - independent channel enables dual-sensor readout or composite amplifier topologies. |
| 7 | –INB | Inverting input of Amplifier B - electrically isolated from Channel A; supports differential pair or independent signal paths. |
| 8 | +INB | Noninverting input of Amplifier B - identical DC specs to +INA; enables matched dual-channel instrumentation designs. |
Key Features
| Feature | Design Value |
|---|---|
| Micropower Operation | 54µA per amplifier at 3V enables >1-year battery life in continuous-sensing IoT nodes using CR2032 cells. |
| Ultra-Low Input Bias Current | ≤50pA up to 85°C ensures <1µV error with 20MΩ source impedance - essential for pH probes and piezoelectric sensors. |
| High CMRR & PSRR | 95dB CMRR and 100dB PSRR minimize interference from motor drivers, switching regulators, or RF-coupled noise in mixed-signal systems. |
| Extended Temperature Grade | H-grade (–40°C to 125°C) qualification enables deployment in under-hood automotive, downhole tools, and industrial PLC modules. |
| Rail-to-Rail Input/Output | Full V– to V+ common-mode range and output swing maximize signal fidelity in 3.3V systems, eliminating need for external level shifters. |

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#TRPBF | I-grade (–40°C to 85°C); otherwise identical electrical specs and pinout. | Suitable for commercial/industrial equipment without extended temperature requirements. | Select when full H-grade thermal margin is unnecessary and cost sensitivity is higher. |
| ADA4522-2ARZ | Zero-drift architecture; 2.5µV max VOS, 0.015µV/°C drift, but 800µA supply current per amp. | Better DC precision but incompatible with micropower (<100µA) systems. | Choose only if ultra-low drift dominates over battery life or thermal dissipation constraints. |
Compared with LTC6078IMS8#TRPBF, the LTC6078HMS8#TRPBF adds guaranteed 125°C operation for harsh environments, while ADA4522-2ARZ trades 15× higher supply current for 10× lower drift-making it viable only in AC-powered precision instruments.

FAQ
What is the maximum operating temperature for the LTC6078HMS8#TRPBF?
The LTC6078HMS8#TRPBF is specified for continuous operation from –40°C to 125°C, with junction temperature limited to 150°C. This H-grade qualification makes it suitable for under-hood automotive, downhole, and industrial control applications where ambient temperatures exceed standard commercial or industrial grades.
Does the LTC6078HMS8#TRPBF include shutdown functionality?
No, the LTC6078HMS8#TRPBF in the 8-lead MSOP package does not include shutdown pins. Shutdown capability (SHDN_A/SHDN_B) is only available on the 10-lead DFN variant (LTC6078HDD#TRPBF). The MS8 version operates continuously when powered and draws 54µA per amplifier at 3V.
Can the LTC6078HMS8#TRPBF drive capacitive loads reliably?
Yes, the LTC6078HMS8#TRPBF is stable driving up to 200pF in unity-gain configuration. For larger loads, adding a small series resistor (e.g., 10–50Ω) between the output and capacitive node improves phase margin and prevents peaking-verified in Figure 19 of the official datasheet.
What is the input bias current specification for LTC6078HMS8#TRPBF at 125°C?
The datasheet specifies maximum input bias current of 50pA at ≤85°C and 350pA at ≤125°C (H-grade, VCM = V+/2). At 125°C, typical IB remains below 150pA, ensuring usable performance in high-temperature sensor interfaces despite the elevated limit.
Is the LTC6078HMS8#TRPBF RoHS-compliant and lead-free?
Yes, the LTC6078HMS8#TRPBF is lead-free and RoHS-compliant, indicated by the "#PBF" suffix. It uses matte tin lead finish and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), allowing unlimited floor life at ≤30°C/60% RH.
