Product details
Overview
LT6654BMPS6-4.096#TRMPBF 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#TRMPBF datasheet, LT6654BMPS6-4.096#TRMPBF pinout, LT6654BMPS6-4.096#TRMPBF application, or LT6654BMPS6-4.096#TRMPBF equivalent, key selection criteria include guaranteed performance across extended temperature range (–55°C to 125°C), low 1.6ppmP-P (0.1Hz–10Hz) noise, and ability to both source and sink current without external components.
Technical Context
The LT6654BMPS6-4.096#TRMPBF uses curvature-compensated bandgap architecture to achieve stable 4.096V output with minimal thermal hysteresis (50ppm over –55°C to 125°C in TSOT-23). Its buffered output stage enables precise load regulation (8ppm/mA max sourcing, 30ppm/mA max sinking) and low 100mV dropout at 10mA.
Designed for harsh environments, it features AEC-Q100-compatible qualification (MP-grade), 350µA typical supply current, and full specification across –55°C to 125°C - including line regulation (5ppm/V max), long-term drift (60ppm/√kHr), and 150µs turn-on time with 1µF load capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±0.10% (±4.1mV) initial tolerance - matches 12-bit DAC full-scale reference requirement. |
| Temp Coefficient | 20ppm/°C max - ensures ≤1.02mV drift over –55°C to 125°C ambient range. |
| Noise (0.1–10Hz) | 1.6ppmP-P (6.6µVP-P) - enables <18-bit effective resolution in precision ADC systems. |
| Output Drive | ±10mA sourcing/sinking - eliminates need for external buffer in 12-bit SAR ADC reference circuits. |
| Supply Range | Up to 36V input - supports direct connection to unregulated 24V industrial rails without pre-regulation. |
| Operating Temp | –55°C to 125°C - qualified for under-hood automotive and downhole industrial applications. |
| Dropout Voltage | 100mV max at 10mA - allows operation with only 4.196V input for 4.096V output. |
Pinout & Package
LT6654BMPS6-4.096#TRMPBF is housed in a 6-lead ThinSOT™ (TSOT-23) package, 1mm profile, RoHS-compliant, tape-and-reel (500 pcs).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 2) | Primary Device Ground | Star-ground connection point for load and internal circuitry; must be low-impedance path to system ground. |
| VIN (Pin 4) | Power Supply Input | Accepts 4.596V–36V; requires ≥0.1µF bypass capacitor to GND for stability and transient immunity. |
| VOUT (Pin 6) | Reference Output | Delivers regulated 4.096V; requires ≥1µF output capacitor for stability and low-noise performance. |
| GND (Pin 1) | Internal Function Ground | Internally connected to die substrate; must be tied to Pin 2 ground near PCB pad to minimize thermal gradients. |
| DNC (Pin 3) | Do Not Connect | No internal connection; floating or leakage to VIN/GND degrades accuracy and noise performance. |
| DNC (Pin 5) | Do Not Connect | No internal connection; must remain unconnected per datasheet to prevent parametric shift. |
Key Features
| Feature | Design Value |
|---|---|
| Extended Temperature Operation | Specified from –55°C to 125°C - enables use in engine control units and oilfield electronics without derating. |
| Bidirectional Output Drive | Sinks and sources ±10mA - supports active termination, ratiometric sensor excitation, and dual-supply DAC references. |
| Low Long-Term Drift | 60ppm/√kHr - ensures <200ppm total drift after 10 years of continuous operation at 85°C. |
| High PSRR | ≥70dB at 10Hz, >40dB at 10kHz - rejects ripple from noisy DC/DC converters in mixed-signal systems. |
| Low Dropout | 100mV max at 10mA - permits direct use with LDOs delivering 4.2V, reducing BOM count and power loss. |

FAQ
What is the guaranteed initial accuracy of the LT6654BMPS6-4.096#TRMPBF?
The LT6654BMPS6-4.096#TRMPBF has a guaranteed initial output voltage accuracy of ±0.10% (±4.1mV) at 25°C, as specified in the B-grade electrical characteristics table. This tolerance applies across the full –55°C to 125°C operating range and is verified during production test.
Does the LT6654BMPS6-4.096#TRMPBF support negative current sinking?
Yes, the LT6654BMPS6-4.096#TRMPBF can sink up to –10mA while maintaining regulation and specified accuracy. Its bidirectional output stage allows use as a precision negative reference when configured with external resistors, matching positive-reference performance.
What is the minimum input voltage required for the LT6654BMPS6-4.096#TRMPBF to regulate at full load?
At ±10mA output, the LT6654BMPS6-4.096#TRMPBF requires a minimum input voltage of VOUT + 100mV = 4.196V to maintain regulation. This 100mV dropout is guaranteed across –55°C to 125°C and accounts for worst-case load and temperature conditions.
Can the LT6654BMPS6-4.096#TRMPBF be used in AEC-Q100 automotive applications?
Yes - the LT6654BMPS6-4.096#TRMPBF is MP-grade (–55°C to 125°C) and manufactured with AEC-Q100-aligned process controls. While not formally certified as "AEC-Q100 Grade 0", its qualification scope and reliability testing meet requirements for under-hood and chassis-mounted automotive modules.
What output capacitor value is required for stable operation of the LT6654BMPS6-4.096#TRMPBF?
A minimum 1µF ceramic output capacitor is required for stable operation of the LT6654BMPS6-4.096#TRMPBF. Larger values (e.g., 4.7µF–10µF) improve noise rejection and load transient response but increase turn-on time beyond the specified 150µs.
