Analog Devices Inc. LTC3256HMSE#PBF

Overview

LTC3256HMSE#PBF from Analog Devices is a wide-input low-noise dual-output power supply for generating positive and negative regulated rails. The device uses charge-pump conversion and LDO regulation to create compact bipolar supplies for industrial and automotive analog systems.

As part of the LTC3256 product family, LTC3256HMSE#PBF supports high-voltage input operation, positive and negative regulated outputs, low-noise rail generation, low quiescent current, and thermally enhanced MSOP packaging. For engineers reviewing the LTC3256HMSE#PBF datasheet, LTC3256HMSE#PBF pinout, LTC3256HMSE#PBF application, or LTC3256HMSE#PBF equivalent, this device is widely used in automotive sensor supplies, industrial analog rails, instrumentation, op amp bias, data acquisition systems, and low-noise bipolar power architectures.

Technical Context

In industrial and automotive analog systems, LTC3256HMSE#PBF operates as a bipolar rail generator that accepts a high input voltage and produces positive and negative low-noise supplies.

The charge-pump architecture reduces the need for inductors, while LDO regulation improves output noise for amplifiers, sensors, and converter front ends. This makes the device useful around precision signal chains where supply ripple directly affects measurement quality.

LTC3256HMSE#PBF is commonly used when a board needs compact positive and negative rails from a high-voltage input without adding a separate inductor-based inverting converter and post regulators.

Key Specifications

Pinout & Package

The LTC3256HMSE#PBF pinout includes high-voltage input, charge-pump flying-capacitor pins, positive and negative outputs, feedback/setting functions, shutdown/control pins, and ground connections.

For PCB design, charge-pump capacitors and output capacitors should be close to the IC, and low-noise output traces should be routed away from high-current charging paths.

Key Features

• Generates positive and negative rails from high input voltage.
• Charge-pump topology avoids inductors.
• LDO regulation supports low-noise outputs.
• Low quiescent current suits always-on analog functions.
• MSOP package supports compact industrial layouts.
• Useful for sensors, op amps, and data acquisition rails.

Applications

Equivalent & Alternatives

When evaluating a LTC3256HMSE#PBF equivalent, engineers should compare input voltage, positive/negative output capability, noise, quiescent current, package, and charge-pump capacitor requirements.

Compared with LTC3260HMSE#PBF, LTC3256HMSE#PBF targets high-voltage input bipolar rail generation. LTC3256HMSE#PBF vs LT3095EUDD#PBF selection depends on input range, output current, noise, package, and rail polarity requirements.

Quality

LTC3256HMSE#PBF should be sourced as original Analog Devices components through traceable channels. Quality checks may include MSOP package inspection, top-mark validation, solderability testing, and positive/negative output verification.

Production validation should include output noise, charge-pump capacitor placement, load transients, thermal behavior, input range, and analog signal-chain performance.
