Product details
Overview
LT6654BMPS6-3#TRPBF from Analog Devices is a precision 3.0V voltage reference IC with ±0.10% initial accuracy, 20ppm/°C max temperature drift, and ±10mA output drive capability in a 6-lead TSOT-23 package. It operates from –55°C to 125°C and supports wide input supply up to 36V, making it suitable for high-reliability automotive sensor signal conditioning and industrial data acquisition systems.
For engineers reviewing the LT6654BMPS6-3#TRPBF datasheet, LT6654BMPS6-3#TRPBF pinout, LT6654BMPS6-3#TRPBF application, or LT6654BMPS6-3#TRPBF equivalent, key selection criteria include guaranteed operation across –55°C to 125°C, low 1.7ppmP-P (0.1Hz–10Hz) noise, 8ppm/mA load regulation (sourcing), and AEC-Q100-compliant performance in harsh environments.
Technical Context
The LT6654BMPS6-3#TRPBF integrates a curvature-compensated bandgap core with a low-output-impedance buffer stage, enabling precise sourcing and sinking of ±10mA while maintaining tight load regulation. Its architecture supports stable operation with only a 1µF output capacitor and tolerates input transients via internal robustness design.
It features dual-mode operation: as a positive 3.0V reference when sourcing current, and as a precision negative reference when sinking current-without requiring external components. Line regulation is specified at 5ppm/V up to 36V, and dropout voltage remains ≤100mV at 10mA sourcing.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Initial Accuracy | ±0.10% max - ensures <±3mV absolute error at 25°C without calibration |
| Temp Coefficient | 20ppm/°C max over –55°C to 125°C - limits drift to <±2.4mV across full range |
| Output Noise | 1.7ppmP-P (0.1Hz–10Hz) - enables 18-bit+ resolution in low-frequency measurement systems |
| Load Regulation | 8ppm/mA max (sourcing), 20ppm/mA max (sinking) - maintains stability under dynamic load changes |
| Supply Range | Up to 36V input - simplifies power architecture in 24V industrial or automotive battery-supplied systems |

Pinout & Package
LT6654BMPS6-3#TRPBF uses a 6-lead Plastic TSOT-23 (S6) package, 2.9mm × 1.6mm × 1.0mm profile, with exposed pad not connected. Pin 1 and Pin 5 are DNC (Do Not Connect); Pin 2 is NC (Not Connected); Pins 3 and 4 are GND (star-ground connection required); Pin 6 is VOUT.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | DNC | Internally connected; must float or be grounded with minimal leakage to avoid error injection |
| Pin 2 | NC | No internal connection; may be tied to VIN, VOUT, GND, or left floating per layout needs |
| Pin 3 | GND | Internal function ground; must connect near Pin 4 to minimize ground loop errors |
| Pin 4 | GND | Primary device ground; star-point for load and internal GND connections |
| Pin 5 | VOUT | Main output terminal; requires ≥1µF ceramic capacitor to GND for stability |
| Pin 6 | VOUT | Secondary output terminal; tied directly to Pin 5 for optimal load regulation |
Key Features
| Feature | Design Value |
|---|---|
| Bipolar output drive | Sources and sinks ±10mA - eliminates need for external op-amp buffers in active reference designs |
| Low thermal hysteresis | 50ppm max over –55°C to 125°C cycle - preserves calibration integrity after thermal cycling |
| High PSRR | –70dB at 100Hz - rejects ripple from noisy DC/DC converters in mixed-signal PCBs |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3430RTER | 3.0V, ±0.05% initial accuracy, 6ppm/°C drift, 3.3V min supply, SOT-23-6 | Higher accuracy but narrower temp range (–40°C to 125°C); no sink capability | Preferred where ultra-low drift dominates over extended cold operation and bipolar drive |
| ADR4530BRZ | 3.0V, ±0.02% initial accuracy, 3ppm/°C drift, 3.6V min supply, SOIC-8 | Lower noise (1.2ppmP-P) and better long-term stability, but larger package and no sink current | Selected for lab-grade instrumentation needing best-in-class stability, not space-constrained automotive modules |

FAQ
What is the maximum input voltage rating for LT6654BMPS6-3#TRPBF?
The LT6654BMPS6-3#TRPBF has an absolute maximum input voltage of 38V relative to GND. However, its specified operating range extends to 36V, and line regulation is guaranteed at 5ppm/V across that full range. For high-voltage applications (>30V), Analog Devices recommends adding a 10Ω + 1µF RC input filter to suppress transients during output short-circuit events.
Does LT6654BMPS6-3#TRPBF support negative reference operation?
Yes, the LT6654BMPS6-3#TRPBF can operate as a precision negative reference by sinking current from a virtual ground node. Its ability to source and sink ±10mA with matched load regulation (20ppm/mA sink vs. 8ppm/mA source) enables true bipolar reference configurations without external circuitry-unlike most single-quadrant references.
What is the long-term drift specification for LT6654BMPS6-3#TRPBF?
The LT6654BMPS6-3#TRPBF exhibits 60ppm/√kHr long-term drift in the TSOT-23 (S6) package. This logarithmic aging behavior means drift slows over time: ~60ppm in the first 1000 hours, ~20ppm in the second 1000 hours, and diminishing thereafter-critical for systems requiring multi-year calibration stability without field adjustment.
Is LT6654BMPS6-3#TRPBF pin-compatible with other LT6654 variants?
Yes, all LT6654 S6-package variants-including LT6654BMPS6-3#TRPBF-share identical 6-lead TSOT-23 pinout and footprint. The same PCB layout supports any output voltage (1.25V–5V) and grade (A/B, I/H/MP), enabling design reuse and simplified inventory management across reference voltage options.
What decoupling capacitors are required for stable operation of LT6654BMPS6-3#TRPBF?
The LT6654BMPS6-3#TRPBF requires a minimum 1µF ceramic capacitor from VOUT to GND for stability, and a 0.1µF capacitor from VIN to GND. Larger output capacitance (e.g., 10µF) is acceptable and reduces turn-on time but increases settling delay; input capacitance >0.1µF is recommended in high-noise environments or when VIN exceeds 30V to prevent transient overvoltage.
