Product details
Overview
LT6654BHS6-4.096#TRMPBF from Analog Devices is a precision 4.096V voltage reference IC in SOT-23-6 package, rated for –40°C to 125°C operation. It delivers ±0.10% initial accuracy, 20ppm/°C max temperature drift, 1.6ppmP-P (0.1Hz–10Hz) low noise, ±10mA output drive, and operates up to 36V supply - ideal for high-resolution ADC/DAC biasing in automotive sensor modules.
For engineers reviewing the LT6654BHS6-4.096#TRMPBF datasheet, LT6654BHS6-4.096#TRMPBF pinout, LT6654BHS6-4.096#TRMPBF application, or LT6654BHS6-4.096#TRMPBF equivalent, this page provides verified specifications, thermal stability data, load regulation behavior at 10mA, dropout voltage under sourcing/sinking conditions, and validated alternatives for industrial and automotive-grade designs.
Technical Context
The LT6654BHS6-4.096#TRMPBF uses curvature-compensated bandgap architecture with internal buffering to achieve low thermal hysteresis (40ppm over –40°C to 125°C in SOT-23) and stable 4.096V output across wide input voltage (VIN ≥ VOUT + 0.5V) and load current (±10mA) ranges.
It supports bidirectional current flow - sourcing and sinking up to ±10mA - enabling use as both positive reference and negative reference with matched precision. Its 100mV max dropout voltage at 10mA sourcing ensures operation with minimal headroom in low-voltage systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±0.10% - precisely matches 12-bit full-scale ADC reference for zero-error digital conversion |
| Temp Coefficient | 20ppm/°C max - limits error to ≤0.82mV over –40°C to 125°C ambient range |
| Output Noise | 1.6ppmP-P (0.1Hz–10Hz) - contributes <6.6µVP-P noise to 4.096V output, critical for sub-LSB measurement stability |
| Load Regulation | 8ppm/mA max (sourcing), 20ppm/mA max (sinking) - ensures <82µV shift per mA load change at 4.096V |
| Line Regulation | 5ppm/V max - holds output within ±17µV over full 4.6V to 36V input range |
| Dropout Voltage | 100mV max at 10mA sourcing - enables operation with only 4.196V supply, supporting low-power battery systems |
| Supply Current | 350µA to 600µA - ultra-low quiescent draw preserves battery life in portable instrumentation |
Pinout & Package
LT6654BHS6-4.096#TRMPBF is housed in a 6-lead Plastic TSOT-23 (S6) package, 1mm profile, RoHS-compliant, tape-and-reel (500 pcs).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 2) | Primary Device Ground | Mandatory star-ground connection point for load and internal circuitry; defines reference potential |
| VIN (Pin 4) | Power Supply Input | Accepts 4.6V to 36V; requires 0.1µF bypass capacitor to GND for transient immunity |
| VOUT (Pin 5) | Reference Output | Delivers regulated 4.096V; requires ≥1µF output capacitor for stability and low-noise performance |
| VOUT (Pin 6) | Reference Output | Internally tied to Pin 5; must be connected externally to ensure proper load regulation |
| DNC (Pin 1) | Do Not Connect | Internally connected; external connection risks leakage current and accuracy degradation |
| NC (Pin 3) | No Internal Connection | May be left floating or tied to GND/VIN/VOUT; no functional impact if unused |
Key Features

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% initial accuracy, 3ppm/°C drift, SOIC-8, 1.2mA IQ | Lower drift but higher power and larger package; not qualified for >105°C ambient | Select for lab-grade instrumentation where ultra-low drift outweighs size/power penalties |
| ADR4540BRZ | 4.096V, 0.02% initial accuracy, 3ppm/°C drift, SOIC-8, 950µA IQ, AEC-Q200 | Higher accuracy and lower drift, but SOIC-8 footprint incompatible with space-constrained PCBs | Choose for automotive control modules requiring AEC-Q200 compliance and tighter initial tolerance |

FAQ
What is the maximum operating temperature range for the LT6654BHS6-4.096#TRMPBF?
The LT6654BHS6-4.096#TRMPBF is fully specified from –40°C to 125°C. This H-grade rating is confirmed in the official Analog Devices datasheet Rev. I, Order Information table, and Absolute Maximum Ratings section. Operation beyond 125°C risks permanent damage or parametric shift, and the device is not characterized for reliability above this limit. The LT6654BHS6-4.096#TRMPBF maintains its 20ppm/°C drift and ±0.10% accuracy across this full range.
Does the LT6654BHS6-4.096#TRMPBF support sinking current, and what is the maximum sink capability?
Yes, the LT6654BHS6-4.096#TRMPBF supports bidirectional current flow and can sink up to –10mA while maintaining regulation. Per the Electrical Characteristics table (Rev. I, p.6), sink load regulation is specified at 20ppm/mA max, and output short-circuit current to GND is 40mA. This capability allows the LT6654BHS6-4.096#TRMPBF to function as a precision negative reference in configurations where the output is grounded and VIN is negative relative to GND.
What is the recommended output capacitor value for stable operation of the LT6654BHS6-4.096#TRMPBF?
The LT6654BHS6-4.096#TRMPBF requires a minimum 1µF ceramic output capacitor connected directly between VOUT (Pins 5 & 6) and GND (Pin 2) for stable operation. This is explicitly stated in the Pin Functions section (Rev. I, p.12) and Applications Information (Rev. I, p.14). Larger values (e.g., 10µF) improve PSRR and low-frequency noise rejection but increase turn-on time. The 1µF value balances stability, transient response, and board space for most applications using the LT6654BHS6-4.096#TRMPBF.
How does the LT6654BHS6-4.096#TRMPBF compare to the A-grade version LT6654AHS6-4.096#TRMPBF in accuracy and drift?
The LT6654BHS6-4.096#TRMPBF has ±0.10% initial accuracy and 20ppm/°C max temperature drift, whereas the A-grade LT6654AHS6-4.096#TRMPBF offers ±0.05% initial accuracy and 10ppm/°C max drift. Both share identical package (SOT-23-6), temperature range (–40°C to 125°C), noise (1.6ppmP-P), and output drive (±10mA). The B-grade LT6654BHS6-4.096#TRMPBF trades tighter tolerances for cost efficiency in applications where 0.1% system-level accuracy is sufficient.
Is the LT6654BHS6-4.096#TRMPBF AEC-Q100 qualified for automotive use?
The LT6654BHS6-4.096#TRMPBF itself is not AEC-Q100 qualified; however, Analog Devices offers automotive-grade variants denoted by the #W suffix (e.g., LT6654BHS6-4.096#WTRMPBF). As stated in the Order Information section (Rev. I, p.4), only parts with the #W designation undergo controlled manufacturing and reliability testing per AEC-Q100. The standard LT6654BHS6-4.096#TRMPBF meets the same electrical specs and temperature range but lacks automotive qualification documentation and screening.
