Product details
Overview
LT6654BMPS6-4.096#TRPBF from Analog Devices is a precision 4.096V 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 voltages up to 36V, making it suitable for high-reliability industrial data acquisition and automotive sensor signal conditioning.
For engineers reviewing the LT6654BMPS6-4.096#TRPBF datasheet, LT6654BMPS6-4.096#TRPBF pinout, LT6654BMPS6-4.096#TRPBF application, or LT6654BMPS6-4.096#TRPBF equivalent, key selection criteria include guaranteed operation across –55°C to 125°C, low 1.6ppmP-P (0.1Hz–10Hz) noise, 5ppm/V line regulation, and sink/source capability enabling bidirectional current handling in precision regulator feedback loops.
Technical Context
The LT6654BMPS6-4.096#TRPBF uses curvature-compensated bandgap architecture with internal buffered output stage, delivering stable 4.096V reference voltage with load regulation of ≤8ppm/mA (sourcing) and ≤20ppm/mA (sinking) over full temperature range. Its design integrates low thermal hysteresis (50ppm over –55°C to 125°C in TSOT-23) and long-term drift of 60ppm/√kHr.
It features a 100mV max dropout voltage at ±10mA, 350µA typical supply current, and 150µs turn-on time with 1µF load capacitor. The device supports both positive and negative reference configurations due to symmetrical ±10mA sourcing/sinking capability and rail-to-rail compatible output stage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±0.10% (±4.1mV) initial tolerance - enables direct interface with 12-bit ADCs without gain calibration. |
| Temp Coefficient | 20ppm/°C max - ensures ≤1.024mV total drift over –55°C to 125°C span, critical for high-temperature industrial sensors. |
| Noise (0.1–10Hz) | 1.6ppmP-P (6.6µVP-P) - minimizes quantization uncertainty in 16-bit+ data acquisition systems. |
| Line Regulation | 5ppm/V max (≤20.5µV/V) - maintains stability across wide 4.596V–36V input range, supporting unregulated power rails. |
| Load Regulation | 8ppm/mA max sourcing, 20ppm/mA max sinking - allows stable operation under dynamic load changes in closed-loop regulators. |
| Operating Temp | –55°C to 125°C - qualified for extended-range industrial and automotive under-hood applications. |
| Supply Current | 350µA typical - enables ultra-low-power battery-operated instrumentation with minimal quiescent burden. |
Pinout & Package
Package: 6-lead TSOT-23 (Thin Small Outline Transistor), 1mm profile, surface-mount. Pin 1 is DNC (Do Not Connect); Pin 2 is NC (Not Connected); Pins 3 and 4 are GND (star-ground connection required); Pin 5 is VOUT; Pin 6 is VOUT (tie to Pin 5 for optimal load regulation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (DNC) | Internally connected, no external connection | Leakage current must be minimized; floating or tying to VIN/GND risks performance degradation. |
| Pin 2 (NC) | No internal connection | May be left floating, tied to VIN, VOUT, or GND - no functional impact on reference operation. |
| Pin 3 (GND) | Internal ground reference node | Must be connected to system ground near Pin 4 to minimize ground loop errors and thermal gradients. |
| Pin 4 (GND) | Primary device ground terminal | Star-ground point for load return and Pin 3; critical for achieving specified load regulation and noise performance. |
| Pin 5 (VOUT) | Main reference output | Requires ≥1µF ceramic output capacitor for stability; drives ±10mA with <1Ω output impedance at DC. |
| Pin 6 (VOUT) | Secondary output terminal | Must be shorted to Pin 5 externally to ensure matched current sharing and optimal load regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ±10mA output drive | Enables use as both positive and negative reference in dual-supply systems without external components. |
| Low 1.6ppmP-P (0.1–10Hz) noise | Reduces effective resolution loss in precision ADCs - adds <0.02 LSB noise to 16-bit 4.096V full-scale conversion. |
| 20ppm/°C max tempco over –55°C to 125°C | Guarantees <±2.05mV total error across full operating range - meets AEC-Q100 Grade 0 requirements. |
| 100mV max dropout at ±10mA | Supports operation with input as low as 4.196V, enabling compatibility with low-headroom LDOs and battery-powered designs. |
| 60ppm/√kHr long-term drift | Ensures <±60ppm (±0.25mV) output shift after 1000 hours - critical for field-deployed test equipment requiring recalibration intervals >1 year. |

FAQ
What is the guaranteed operating temperature range for LT6654BMPS6-4.096#TRPBF?
The LT6654BMPS6-4.096#TRPBF is fully specified from –55°C to 125°C, meeting MP-grade qualification. This extended range is confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables of the official Analog Devices datasheet Rev. I, and applies across all electrical parameters including initial accuracy, temperature coefficient, and load regulation.
Does LT6654BMPS6-4.096#TRPBF support sinking current, and what is the maximum sink current?
Yes, the LT6654BMPS6-4.096#TRPBF supports sinking up to –10mA while maintaining specified accuracy and regulation. Its bidirectional output stage allows it to operate as a precision negative reference; sink load regulation is 20ppm/mA max over the full –55°C to 125°C range, as documented in the Load Regulation section of the datasheet.
What output capacitor value is required for stable operation of LT6654BMPS6-4.096#TRPBF?
A minimum 1µF ceramic output capacitor is required for stable operation of LT6654BMPS6-4.096#TRPBF, as explicitly stated in the Pin Functions and Applications Information sections. Larger values (e.g., 10µF) are acceptable and may improve transient response, but reduce turn-on time; the 1µF value optimizes stability, noise, and settling performance per the recommended test circuit in Figure 1.
How does the noise performance of LT6654BMPS6-4.096#TRPBF compare to other 4.096V references?
The LT6654BMPS6-4.096#TRPBF delivers 1.6ppmP-P (6.6µVP-P) low-frequency noise (0.1Hz–10Hz), matching the value specified for the LT6654-4.096 variant in Table 1 of the datasheet. This is lower than REF5040IDR (3.5ppmP-P) and comparable to ADR4540BRZ (1.7ppmP-P), making it among the quietest 4.096V references qualified for –55°C operation.
Is LT6654BMPS6-4.096#TRPBF pin-compatible with other LT6654 variants in the same package?
Yes, all LT6654 variants in the 6-lead TSOT-23 package - including LT6654BMPS6-4.096#TRPBF - share identical pinout, footprint, and terminal functions (Pins 1–6 as DNC, NC, GND, GND, VOUT, VOUT). This allows drop-in replacement across output voltages and grade options without PCB modification, provided thermal and layout constraints for the MP-grade temperature range are met.
