Product details
Overview
LT6654BHLS8-4.096 from Analog Devices is a precision 4.096V voltage reference IC in an 8-lead ceramic LCC (LS8) 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 LT6654BHLS8-4.096 datasheet, LT6654BHLS8-4.096 pinout, LT6654BHLS8-4.096 application, or LT6654BHLS8-4.096 equivalent, this page provides verified specifications, LS8 package terminal mapping, real-world use cases in industrial DAQ and AEC-Q100-compliant systems, and validated alternative options with documented functional trade-offs.
Technical Context
The LT6654BHLS8-4.096 integrates a curvature-compensated bandgap core with a buffered output stage, enabling bidirectional ±10mA current sourcing/sinking while maintaining low output impedance and precise load regulation. Its hermetic 5mm × 5mm LS8 package ensures <15ppm thermal hysteresis over –40°C to 125°C and 15ppm/√kHr long-term stability.
Designed for wide-supply applications, it features 100mV max dropout at 10mA source current, 5ppm/V line regulation (up to 36V), and 8ppm/mA load regulation - making it suitable for battery-powered instrumentation where input voltage varies significantly across operating life.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V nominal - matches common 12-bit DAC/ADC full-scale reference points for zero-error digital conversion. |
| Initial Accuracy | ±0.10% max - guarantees ≤±4.1mV absolute error at 25°C without calibration. |
| Temp Coefficient | 20ppm/°C max - limits drift to ≤±2.46mV over –40°C to 125°C ambient range. |
| Output Noise | 1.6ppmP-P (0.1Hz–10Hz) - contributes <6.5µVP-P noise, critical for 18+ bit measurement resolution. |
| Supply Range | Up to 36V - supports direct connection to unregulated industrial rails or automotive battery systems. |
| Output Drive | ±10mA - enables direct driving of ADC reference inputs, op-amp bias networks, and small-signal transducers. |
| Package | 8-pin LS8 (5mm × 5mm ceramic LCC) - hermetic sealing ensures stable performance in high-humidity or extended-temperature environments. |
Pinout & Package
LT6654BHLS8-4.096 uses the 8-pin leadless chip carrier (LS8) package: 5mm × 5mm surface-mount hermetic ceramic LCC with exposed pad (not electrically connected). Pin 1 is top-left corner when marking "544096" is upright; pin numbering follows standard counter-clockwise sequence.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Internal function ground | Must be tied to system ground near Pin 2; not a power return path. |
| GND (Pin 2) | Primary device ground | Star-point connection for load ground and Pin 1; defines reference potential for all internal circuitry. |
| DNC (Pin 3) | Do Not Connect | Internally connected; external connection risks leakage current and accuracy degradation. |
| VIN (Pin 4) | Power supply input | Accepts 4.596V–36V; requires ≥0.1µF bypass capacitor to GND for stability and transient immunity. |
| DNC (Pin 5) | Do Not Connect | Internally connected; floating or routing to other nodes degrades PSRR and noise performance. |
| VOUT (Pin 6) | Reference output | Delivers regulated 4.096V; requires ≥1µF output capacitor for stability and low-noise operation. |
| DNC (Pin 7) | Do Not Connect | Internally connected; no external connection permitted per datasheet. |
| VIN (Pin 8) | Secondary power supply input | Redundant VIN connection - tie to same rail as Pin 4; improves supply rejection under high-frequency noise. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ±10mA output | Enables use as both positive and negative reference (sink mode) without external components - reduces BOM count in dual-rail systems. |
| Hermetic LS8 packaging | Delivers 15ppm thermal hysteresis and 15ppm/√kHr long-term drift - essential for field-deployed test equipment requiring recalibration intervals >5 years. |
| AEC-Q100 qualified | Rated for automotive-grade temperature range (–40°C to 125°C) and reliability testing - approved for engine control, ADAS sensor signal conditioning. |
| Low 1.6ppmP-P noise | Minimizes quantization uncertainty in high-resolution data acquisition - directly supports 18-bit+ SAR and delta-sigma ADC performance. |
| 36V max supply voltage | Eliminates need for pre-regulation in 24V industrial PLC I/O modules or 12V/24V automotive subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT6654AHLS8-4.096 | ±0.05% initial accuracy and 10ppm/°C max drift vs. LT6654BHLS8-4.096's ±0.10% and 20ppm/°C. | Suitable for metrology-grade instruments where tighter initial tolerance justifies higher cost. | Select when absolute accuracy at power-up is prioritized over cost; identical LS8 package and pinout. |
| REF5040IDR | 4.096V output, ±0.05% initial accuracy, but only 3ppm/°C drift and 1.2ppmP-P noise - superior stability and lower noise than LT6654BHLS8-4.096. | Requires external buffer for ±10mA drive; not inherently bidirectional - limits use in sink-mode configurations. | Choose for ultra-low-drift lab equipment where board space allows discrete buffering; not drop-in compatible due to different pin count (SOIC-8 vs LS8). |

FAQ
What is the maximum supply voltage for LT6654BHLS8-4.096?
The LT6654BHLS8-4.096 supports a maximum input voltage of 36V, with absolute maximum rating of 38V. Operation up to 36V enables direct interface with unregulated 24V industrial rails or automotive battery systems without pre-regulation - confirmed in the Absolute Maximum Ratings table and Electrical Characteristics section of the Rev. I datasheet.
Does LT6654BHLS8-4.096 support sinking current?
Yes, LT6654BHLS8-4.096 can sink up to 10mA while maintaining specified accuracy and regulation. This bidirectional capability allows it to serve as a precision negative reference in dual-supply systems - explicitly stated in the DESCRIPTION section and verified in Load Regulation (IOUT(SINK) = 10mA) electrical characteristics.
What is the thermal hysteresis specification for LT6654BHLS8-4.096?
The LT6654BHLS8-4.096 exhibits 15ppm thermal hysteresis over –40°C to 125°C, as specified for the LS8 package variant in the Electrical Characteristics table (Hysteresis row, LS8 column, ∆T = –40°C to 125°C). This value reflects worst-case output shift after thermal cycling and is critical for repeatable measurements in field-deployed equipment.
Is LT6654BHLS8-4.096 qualified for automotive applications?
Yes, LT6654BHLS8-4.096 is AEC-Q100 qualified for automotive applications, with specified operating temperature range of –40°C to 125°C. The datasheet explicitly states "AEC-Q100 Qualified for Automotive Applications" in the FEATURES section and confirms H-grade (–40°C to 125°C) operation in the ORDER INFORMATION tables.
What output capacitor is required for stable operation of LT6654BHLS8-4.096?
LT6654BHLS8-4.096 requires a minimum 1µF output capacitor connected between VOUT and GND for stable operation, as stated in the PIN FUNCTIONS section (Pin 6 description) and APPLICATIONS INFORMATION. Ceramic X7R or C0G types are recommended; larger values improve low-frequency noise suppression but increase turn-on time.
