Key Features
- Dual-output charge pump with boost and inverting modes generates positive and negative rails up to 20 V from a single 4.5 V to 16 V input
- Low-noise switched capacitor topology avoids inductor-generated EMI, critical for precision ADC, DAC, and op-amp supply rails
- 20-lead SSOP package integrates boost and inverting regulators in a compact footprint for split-supply analog front-end designs
Applications
The LTC3265EFE#PBF is designed for precision analog and mixed-signal circuits requiring low-noise positive and negative supply rails from a single input, such as instrumentation amplifier front ends, high-resolution ADC bias networks, and op-amp signal chains. Its switched capacitor architecture eliminates inductor noise, making it suitable for sensitive measurement systems where spectral purity of the supply rail directly impacts signal quality. Applications include portable medical instruments, data acquisition modules, and audio signal processors needing split ±10 V to ±15 V rails.

Frequently Asked Questions
What output voltage range does LTC3265EFE#PBF support and how does the boost and inverting topology generate a split supply?
The LTC3265EFE#PBF supports a positive boost output up to 20 V and an inverted negative output derived from the same switched capacitor network, with an input range of 4.5 V to 16 V. This dual-polarity configuration generates symmetric split rails such as +15 V and -15 V for op-amp circuits from a single positive supply, eliminating the need for a separate negative-rail converter IC.
Why is the inductor-free switched capacitor topology of LTC3265EFE#PBF preferred for precision ADC and DAC power supply designs?
Inductor-based regulators produce switching noise at frequencies from hundreds of kHz to several MHz that can couple into sensitive analog supply pins and degrade ADC dynamic range by 3 dB to 6 dB at high input frequencies. The LTC3265EFE#PBF switched capacitor architecture uses only capacitors as energy storage elements, resulting in significantly lower broadband noise on the output rail and improving SINAD performance in 16-bit or 24-bit data converter systems.
For a portable medical instrument needing dual rails, what input supply range makes LTC3265EFE#PBF compatible with Li-ion battery packs?
The LTC3265EFE#PBF accepts inputs from 4.5 V to 16 V, covering the full discharge range of a 2-cell Li-ion battery pack (approximately 6 V to 8.4 V) and a single-cell pack with a boost stage. A 2-cell configuration supplies the LTC3265EFE#PBF directly, allowing generation of split rails up to 20 V positive and the corresponding negative output for precision amplifier circuits in portable instruments without requiring a separate 12 V or 15 V bus.
