What are the key features of LTC1682CMS8?
- Integrated voltage doubler plus low-noise linear regulator in a single SOIC-8 package eliminates discrete boost converter components for space-constrained designs
- Input voltage range of 1.8 V to 4.4 V makes the LTC1682 compatible with single-cell Li-ion and dual-cell NiMH battery-powered systems
- Switched-capacitor doubler architecture avoids inductor noise, providing a clean regulated output suitable for precision analog and RF circuits
What is LTC1682CMS8 used for?
The LTC1682CMS8 is used in battery-powered portable instruments, handheld medical devices, and wireless sensor nodes where a noise-free boosted voltage rail is needed from a single Li-ion cell. Its 1.8 V to 4.4 V input range and low-noise linear regulator output make it ideal for powering op-amps, ADCs, and RF front-ends that require a regulated supply above the battery voltage without inductor switching noise. Engineers also deploy it in LCD bias generation and EEPROM programming voltage applications in compact consumer electronics.

Frequently Asked Questions
What input voltage range does the LTC1682CMS8 support, and what output voltage does the doubler produce?
The LTC1682CMS8 operates from a 1.8 V to 4.4 V input, with the switched-capacitor doubler stage generating approximately twice the input voltage before the integrated linear regulator produces a clean regulated output. This allows a 3.3 V Li-ion battery to power analog circuits requiring a regulated 5 V or higher clean supply without an inductor-based boost converter.
How does combining a charge pump with a linear regulator benefit noise-sensitive analog designs compared to a standalone boost converter?
A pure switched-capacitor doubler produces switching transients at the clock frequency, typically 300 kHz to 1 MHz, that corrupt sensitive ADC and op-amp measurements. The LTC1682's integrated low-noise linear regulator post-filters these transients, delivering an output noise floor below 50 µVRMS over a 10 Hz to 100 kHz bandwidth, which is 10 to 20 times quieter than a typical inductor-based boost converter output.
In which portable product categories is the LTC1682CMS8 most commonly used instead of a discrete inductor-based boost?
The LTC1682CMS8 is preferred in handheld medical monitors, portable data loggers, and wireless sensor nodes powered by a single Li-ion cell (2.7 V to 4.2 V). Its SOIC-8 footprint with no external inductor reduces PCB area by approximately 30% compared to an equivalent boost converter, while the low-noise output keeps ADC SNR above 80 dB — a key requirement for electrochemical sensors and precision weigh scales operating in the field.
