Product details
Overview
LT6654AMPS6-4.096#TRPBF from Analog Devices is a precision 4.096V voltage reference IC with ±0.05% initial accuracy, 10ppm/°C max temperature drift, and 1.6ppmP-P (0.1Hz–10Hz) low-noise output. It delivers ±10mA drive capability, operates from 4.596V to 36V input, and is fully specified over –55°C to 125°C for high-reliability industrial and automotive sensing systems.
For engineers reviewing the LT6654AMPS6-4.096#TRPBF datasheet, LT6654AMPS6-4.096#TRPBF pinout, LT6654AMPS6-4.096#TRPBF application, or LT6654AMPS6-4.096#TRPBF equivalent, this page provides verified specifications, SOT-23-6 package details, load regulation behavior, thermal hysteresis data, and validated alternative options for precision ADC biasing, sensor excitation, and closed-loop control references.
Technical Context
The LT6654AMPS6-4.096#TRPBF uses curvature-compensated bandgap architecture with internal buffering to achieve low output impedance and precise load regulation. Its ability to both source and sink ±10mA enables bidirectional current operation-critical for active calibration circuits and negative reference configurations without external components.
Designed for extended temperature operation, it features low thermal hysteresis (50ppm over –55°C to 125°C in TSOT-23), long-term stability of 60ppm/√kHr, and AEC-Q100-compliant qualification for automotive-grade reliability. The 100mV max dropout ensures stable regulation even at low VIN–VOUT differentials.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±0.05% - matches 12-bit full-scale ADC reference for zero-code alignment and minimal gain error. |
| Temp Coefficient | 10ppm/°C max - ensures ≤±1.23mV drift across –55°C to 125°C, enabling stable metrology in uncontrolled environments. |
| Output Noise | 1.6ppmP-P (0.1Hz–10Hz) - contributes <6.6µVP-P noise, preserving ENOB in 24-bit delta-sigma converters. |
| Load Regulation | 8ppm/mA max sourcing - maintains ≤±33µV shift per mA load change, critical for dynamic sensor excitation circuits. |
| Line Regulation | 5ppm/V max - limits output variation to <20.5µV per volt input change, supporting wide-input industrial power rails. |
| Dropout Voltage | 100mV max at 10mA - allows operation with only 4.196V supply, easing compatibility with low-voltage LDOs and battery systems. |
| Supply Range | 4.596V to 36V - accommodates 5V, 12V, and 24V industrial buses without external regulators or level-shifting. |
Pinout & Package
LT6654AMPS6-4.096#TRPBF is housed in a 6-lead Plastic TSOT-23 (S6) package, 2.9mm × 1.6mm × 1.0mm profile, optimized for space-constrained PCB layouts and high-temperature reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 2) | Primary Device Ground | Mandatory star-ground connection point for load and internal circuitry; determines reference potential integrity. |
| VIN (Pin 4) | Power Supply Input | Accepts 4.596V–36V; requires ≥0.1µF bypass capacitor to GND for PSRR and transient immunity. |
| VOUT (Pin 6) | Reference Output | Delivers regulated 4.096V; requires ≥1µF output capacitor for stability and low-noise performance. |
| DNC (Pin 1 & 5) | Do Not Connect | Internally connected; external routing causes leakage paths and degrades accuracy or thermal stability. |
| NC (Pin 3) | No Internal Connection | May be left floating or tied to GND/VIN/VOUT; no functional impact but avoids floating node EMI pickup. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Temperature Range | –55°C to 125°C operation with full spec compliance-enables deployment in engine bays, downhole tools, and industrial ovens. |
| Bidirectional Output Drive | ±10mA sourcing/sinking capability eliminates need for external op-amps in active calibration loops or dual-supply reference designs. |
| Low Thermal Hysteresis | 50ppm over –55°C to 125°C cycle-minimizes repeatability errors in field-deployed test equipment and recalibration-critical systems. |
| High PSRR | >70dB at 100Hz-rejects ripple from switching supplies, preserving reference integrity in mixed-signal embedded controllers. |
| AEC-Q100 Qualified | Qualified for automotive applications per Grade 1 requirements-supports use in ADAS sensors, battery management, and powertrain control units. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5040IDR | 4.096V, ±0.05%, 3ppm/°C drift, SOIC-8, 1.2mA quiescent current | Lower drift but larger package and higher supply current; not rated for –55°C operation | Preferred where ultra-low drift dominates over size, temperature range, or power constraints |

FAQ
What is the operating temperature range for the LT6654AMPS6-4.096#TRPBF?
The LT6654AMPS6-4.096#TRPBF is fully specified from –55°C to 125°C, making it suitable for extreme-environment applications such as under-hood automotive electronics, downhole oilfield tools, and industrial furnace controls. This MP-grade rating exceeds standard industrial and automotive temperature requirements and is validated per AEC-Q100 Grade 1.
Does the LT6654AMPS6-4.096#TRPBF support sinking current, and how much?
Yes, the LT6654AMPS6-4.096#TRPBF can sink up to –10mA while maintaining regulation and specified accuracy. This bidirectional capability enables its use in active calibration circuits, negative reference generation, and ratiometric sensor interfaces where current must flow into the reference terminal-without requiring external amplifiers or discrete components.
What is the recommended output capacitor for stable operation of the LT6654AMPS6-4.096#TRPBF?
An output capacitor of at least 1µF is required for stable operation of the LT6654AMPS6-4.096#TRPBF. Ceramic X7R or C0G types are preferred for low ESR and minimal microphonic effects. Larger values (e.g., 10µF) further reduce noise and improve transient response but increase turn-on time; the 1µF value balances stability, speed, and board area efficiency.
How does the LT6654AMPS6-4.096#TRPBF compare to the LT6654BMP version?
The LT6654AMPS6-4.096#TRPBF has ±0.05% initial accuracy and 10ppm/°C max temperature coefficient, whereas the LT6654BMPS6-4.096#TRPBF offers ±0.10% accuracy and 20ppm/°C drift. Both share identical package, temperature range (–55°C to 125°C), and electrical features-but the 'A' grade delivers tighter DC specs for metrology-grade applications where first-pass calibration margin is critical.
Is the LT6654AMPS6-4.096#TRPBF pin-compatible with other LT6654 variants in SOT-23-6?
Yes, all LT6654 variants in the SOT-23-6 (S6) package-including LT6654AMPS6-4.096#TRPBF, LT6654BHS6-4.096#TRPBF, and LT6654AIS6-4.096#TRPBF-share identical pinout, footprint, and terminal functions. This allows drop-in replacement during design iteration or qualification, provided the target application's accuracy, drift, and temperature requirements align with the selected grade.
