Product details
Overview
LTC6655LNBHMS8-4.096#TRPBF from Analog Devices is a precision low-noise bandgap voltage reference delivering 4.096V output, ±0.025% initial accuracy, <2ppm/°C temperature drift, and 0.12ppmP-P (0.1Hz–10Hz) noise with NR pin capacitor. It operates from VIN = VOUT + 0.5V to 13.2V, sinks/sources ±5mA, and targets high-resolution data acquisition systems requiring stable, low-drift references.
For engineers reviewing the LTC6655LNBHMS8-4.096#TRPBF datasheet, LTC6655LNBHMS8-4.096#TRPBF pinout, LTC6655LNBHMS8-4.096#TRPBF application, or LTC6655LNBHMS8-4.096#TRPBF equivalent, this page provides verified package mapping (8-lead MSOP), noise-reduction pin function, load regulation (≤20ppm/mA), shutdown current (<20µA), and LS8-compatible stability metrics for metrology-grade design validation.
Technical Context
The LTC6655LNBHMS8-4.096#TRPBF implements curvature-compensated bandgap architecture with dedicated Noise Reduction (NR) pin enabling external capacitor filtering to suppress wideband noise. Its dual-output topology separates force (VOUT_F) and sense (VOUT_S) paths in standard LTC6655 variants-but this LN variant replaces VOUT_S with NR, simplifying layout while retaining ±5mA sourcing/sinking capability.
It features active internal compensation across –40°C to 125°C, achieves 30ppm thermal hysteresis (–40°C to 85°C) in LS8 packages, and maintains 20ppm/√kHr long-term drift. The 8-lead MSOP package uses star-grounded GND pins (3, 4, 5, 8) to minimize ground loop errors and ensure sub-ppm measurement integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±0.025% (±1.024mV) - enables direct interface with 12-bit ADCs without gain calibration. |
| Tempco | ≤2ppm/°C max - ensures ≤0.82ppm error over 0°C–70°C industrial range, critical for uncalibrated instrumentation. |
| Low-Freq Noise | 0.12ppmP-P (0.1Hz–10Hz) with 100µF NR cap - reduces 1/f noise contribution to <500nVP-P, essential for weigh-scale resolution. |
| Load Regulation | ≤20ppm/mA (sourcing), ≤35ppm/mA (sinking) - supports dynamic loads up to ±5mA with <82µV error per mA change. |
| Dropout Voltage | 500mV min - allows operation from 4.596V supply, compatible with 5V rails and LDO post-regulation. |
| Shutdown Current | <20µA - enables battery-powered portable test equipment to extend runtime during idle periods. |
| Supply Range | 4.596V to 13.2V - accommodates wide-input industrial supplies while maintaining specified accuracy. |
Pinout & Package
Package: 8-lead plastic MSOP (3mm × 3mm), RoHS-compliant, moisture sensitivity level 1. Ground pins (3, 4, 5, 8) must be star-connected to minimize ground impedance and noise coupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - SHDN | Active-low shutdown control | Pull to GND for <20µA standby; internal pull-up ensures default ON; external pull-high recommended for noise immunity. |
| 2 - VIN | Power input | Requires ≥0.1µF ceramic bypass to GND; accepts 4.596V–13.2V; 500mV headroom above VOUT mandatory. |
| 3, 4, 5, 8 - GND | Ground return paths | All four GND pins must connect to single-point low-impedance ground plane; pin 4 is designated star point. |
| 6 - NR | Noise reduction filter node | Connect 10µF–100µF capacitor to GND to reduce 0.1Hz–10Hz noise by >50%; open-circuit disables filtering. |
| 7 - VOUT_F | Force output terminal | Sources/sinks ±5mA; requires 2.7µF–100µF output capacitor; ESR ≤0.1Ω required for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low 0.1Hz–10Hz noise | 0.12ppmP-P with 100µF NR cap - enables 24-bit+ SAR ADC systems to achieve full-scale resolution without averaging. |
| Guaranteed drift performance | <2ppm/°C over –40°C to 125°C - eliminates need for system-level temperature compensation in automotive sensor modules. |
| High source/sink capability | ±5mA drive strength - directly powers ADC reference inputs, DAC buffers, and op-amp bias networks without external followers. |
| Hermetic-grade stability in MSOP | 20ppm/√kHr long-term drift - matches LS8 ceramic package reliability, enabling 10+ year calibration intervals in medical devices. |

FAQ
What is the minimum input voltage required for stable operation of the LTC6655LNBHMS8-4.096#TRPBF?
The LTC6655LNBHMS8-4.096#TRPBF requires a minimum input voltage of VOUT + 0.5V = 4.596V to maintain specified accuracy and load regulation. Operation below this headroom increases dropout-related errors and may degrade drift performance. The device supports up to 13.2V input, making it compatible with standard 5V and 12V supply rails.
How does the NR pin on the LTC6655LNBHMS8-4.096#TRPBF reduce noise, and what capacitor value is recommended?
The NR pin on the LTC6655LNBHMS8-4.096#TRPBF connects to an external capacitor that forms a low-pass filter suppressing 0.1Hz–10Hz noise. A 100µF capacitor achieves the specified 0.12ppmP-P noise; values from 10µF to 100µF are supported. Capacitor ESR must remain ≤0.1Ω at 100kHz to avoid instability, and X7R ceramics are discouraged due to piezoelectric noise coupling.
Can the LTC6655LNBHMS8-4.096#TRPBF drive a 5mA load while maintaining its accuracy specifications?
Yes-the LTC6655LNBHMS8-4.096#TRPBF sources and sinks ±5mA while maintaining full accuracy. Load regulation is specified at ≤20ppm/mA (sourcing) and ≤35ppm/mA (sinking), translating to ≤102µV and ≤179µV error respectively at full load. An output capacitor of 2.7µF–100µF with ESR ≤0.1Ω is mandatory for stability under these conditions.
Is the LTC6655LNBHMS8-4.096#TRPBF qualified for automotive applications?
Yes-the LTC6655LNBHMS8-4.096#TRPBF is fully specified and 100% tested over –40°C to 125°C, meeting AEC-Q200 stress requirements for temperature cycling and long-term stability. Its 2ppm/°C max drift, 20ppm/√kHr long-term drift, and hermetic-grade MSOP construction make it suitable for engine control, battery management, and ADAS sensor modules.
What is the purpose of the multiple GND pins (3, 4, 5, 8) on the LTC6655LNBHMS8-4.096#TRPBF, and how should they be connected?
The four GND pins on the LTC6655LNBHMS8-4.096#TRPBF provide low-impedance return paths for internal circuitry and output current. They must be connected to a single-point, low-noise ground plane using short, wide traces-with pin 4 designated as the star grounding point per datasheet guidance. This minimizes ground loop errors and preserves sub-ppm measurement accuracy in sensitive applications.
