Product details
Overview
LTC6255HS6#TRMPBF from Analog Devices (formerly Linear Technology) is a single-channel, rail-to-rail input/output operational amplifier optimized for micropower precision signal conditioning in harsh-temperature environments. It delivers 6.5MHz gain-bandwidth product, 4.5MHz –3dB bandwidth at unity gain, 65µA quiescent current, 350µV max input offset voltage, and operates from 1.8V to 5.25V supply across –40°C to 125°C. It drives capacitive loads up to 100nF while maintaining stability-ideal for battery-powered sensor front-ends and automotive signal chains.
For engineers reviewing the LTC6255HS6#TRMPBF datasheet, LTC6255HS6#TRMPBF pinout, LTC6255HS6#TRMPBF application, or LTC6255HS6#TRMPBF equivalent, this page provides verified functional specifications, thermal-grade package mapping, shutdown timing (50µs turn-on), C-Load™ capacitive drive capability, and real-world ADC driver performance with LTC2361 at 125kSps.
Technical Context
The LTC6255HS6#TRMPBF employs a dual-input PNP/NPN architecture that enables rail-to-rail input operation with bias current cancellation active over 0.2V–(V+–0.2V), delivering ≤50nA max input bias current in that range. Its patented C-Load™ compensation maintains unity-gain stability into 100nF loads without external compensation.
It integrates an active-low SHDN pin with 0.6V threshold referenced to V–, reducing supply current to ≤7µA in shutdown while placing the output in high-impedance state-enabling use in multiplexed analog signal paths. The 6-lead TSOT-23 package supports thermal performance up to 125°C junction temperature with qJA = 192°C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 6.5MHz - enables stable closed-loop gain ≥10 at 650kHz, supporting anti-aliasing filter design with <1% gain error. |
| Quiescent Current | 65µA per amplifier - allows continuous operation for >1 year on a single CR2032 coin cell in low-duty-cycle sensor nodes. |
| Input Offset Voltage | ≤350µV - ensures ≤0.007% full-scale error in 5V-span 12-bit systems without trimming. |
| Rail-to-Rail I/O | VOUT swings within 30mV of V+ and V– - eliminates level-shifting circuitry when interfacing with 1.8V/3.3V ADCs or microcontrollers. |
| Capacitive Load Drive | Stable into 100nF at unity gain - permits direct connection to long PCB traces, EMI filters, or ADC input capacitance without phase-margin degradation. |
| Shutdown Current | ≤7µA - reduces system standby power by >90% versus active mode, critical for ISO 26262-compliant automotive sleep states. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial motor control, and downhole instrumentation applications. |
Pinout & Package
Package: 6-Lead Plastic TSOT-23 (2mm × 2mm × 0.9mm), RoHS-compliant, exposed pad not present in S6 variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply input | Accepts 1.8V–5.25V; requires 0.1µF ceramic bypass capacitor placed adjacent to pin for PSRR optimization. |
| SHDN | Active-low shutdown control | Pulled ≤0.6V above V– to disable; unconnected = enabled; 50µs turn-on time limits wake-up latency in responsive systems. |
| –IN | Inverting input | Supports common-mode voltage from V– –0.1V to V+ +0.1V - enables ground-sensing and overvoltage-tolerant sensor interfaces. |
| OUT | Amplifier output | Delivers ±10mA short-circuit current; rail-to-rail swing enables full utilization of 12-bit ADC input range without external biasing. |
| V– | Negative supply input | Typically grounded; supports split supplies if |V+ − V–| ∈ [1.8V, 5.25V]; bypass capacitor required if floating. |
| +IN | Non-inverting input | Matches –IN voltage range and bias current specs; differential input impedance >1MΩ enables high-Z transducer interfacing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Lower offset (10µV typ), but higher quiescent current (17µA), no shutdown, and only rated to 125°C with derated parameters. | Preferred for ultra-precision DC-coupled systems where offset dominates error budget, but unsuitable for shutdown-controlled power gating. | Select OPA333AIDBVR when sub-50µV offset is mandatory and thermal derating is acceptable; avoid when shutdown or guaranteed 125°C performance is required. |
| MAX44260ASA+T | Higher supply current (120µA), wider supply range (1.8V–5.5V), integrated ESD protection (±8kV HBM), but no specified C-Load™ behavior. | Better suited for industrial fieldbus nodes requiring robustness against cable ESD, but lacks verified 100nF capacitive load stability. | Select MAX44260ASA+T for high-noise factory-floor environments with frequent ESD events; avoid when driving large ADC input capacitances without external compensation. |
Compared with OPA333AIDBVR and MAX44260ASA+T, the LTC6255HS6#TRMPBF uniquely balances guaranteed 125°C operation, 7µA shutdown current, and C-Load™-verified 100nF drive-making it the only choice for thermally constrained, power-gated, high-capacitance ADC interfaces in automotive and industrial edge devices.

FAQ
What is the maximum capacitive load the LTC6255HS6#TRMPBF can drive while remaining unity-gain stable?
The LTC6255HS6#TRMPBF is characterized for unity-gain stability into 100nF capacitive loads, as confirmed in the "Capacitive Load Handling" typical performance graph (Figure G31). This capability is enabled by its proprietary C-Load™ compensation architecture and eliminates the need for external isolation resistors when driving ADC inputs or long PCB traces. Loads exceeding 100nF may require empirical stability verification per application conditions.
Does the LTC6255HS6#TRMPBF support true ground-sensing input operation?
Yes. The LTC6255HS6#TRMPBF accepts input common-mode voltages down to V– – 0.1V, allowing it to accurately sense signals referenced to ground even when V– = 0V. This feature, combined with rail-to-rail output swing, enables direct interfacing with ground-referenced transducers like thermistors or bridge sensors without level-shifting circuitry-critical for precision low-voltage measurement systems.
What is the typical turn-on time for the shutdown function of the LTC6255HS6#TRMPBF?
The LTC6255HS6#TRMPBF exhibits a typical turn-on time of 50µs when the SHDN pin transitions from low (≤0.6V) to high (>1.5V), as specified in the Electrical Characteristics table. This fast wake-up latency supports responsive power management in duty-cycled sensor acquisition systems, such as those used in predictive maintenance edge nodes where rapid signal capture after sleep is essential.
How does the input bias current of the LTC6255HS6#TRMPBF behave across the common-mode voltage range?
The LTC6255HS6#TRMPBF uses active bias current cancellation, resulting in ≤50nA max input bias current when the common-mode voltage is between 0.2V above V– and 0.2V below V+. Outside this range-near the rails-the cancellation circuit disengages, and bias current rises. This behavior is documented in Figures G08 and G09, making the device ideal for high-impedance sources operating within mid-supply ranges, such as photodiode transimpedance amplifiers.
Is the LTC6255HS6#TRMPBF pin-compatible with other members of the LTC6255/LTC6256/LTC6257 family?
No. The LTC6255HS6#TRMPBF uses the 6-lead TSOT-23 package, while LTC6256 (dual) and LTC6257 (quad) variants use 8-, 10-, or 16-lead packages (TSOT-23, MSOP, DFN). Pin compatibility exists only within same-channel-count variants-for example, LTC6255HS6#TRMPBF and LTC6255HDC#TRMPBF share identical pinouts but differ in package (TSOT-23 vs DFN). Always verify mechanical layout before substitution.
