Analog Devices Inc. LTC3260HMSE#PBF

Overview

LTC3260HMSE#PBF from Analog Devices is a low-noise dual-supply generator that combines an inverting charge pump with positive and negative LDO post regulators. The device is intended for precision analog systems that need clean bipolar rails from a single positive supply without using an inductor-based converter.

As part of the LTC3260 product family, LTC3260HMSE#PBF provides charge-pump inversion, post-regulated positive and negative outputs, low-noise rail generation, shutdown control, and compact MSOP packaging for mixed-signal PCB layouts. For engineers reviewing the LTC3260HMSE#PBF datasheet, LTC3260HMSE#PBF pinout, LTC3260HMSE#PBF application, or LTC3260HMSE#PBF equivalent, this device is widely used in precision op amp supplies, ADC and DAC rails, sensor interfaces, instrumentation, portable test equipment, and low-noise analog systems.

Technical Context

In precision analog designs, LTC3260HMSE#PBF operates as a bipolar supply generator. The inverting charge pump creates a negative rail from a positive input, while the positive and negative LDO regulators post-regulate the outputs for lower noise and improved supply quality.

Because the architecture is charge-pump based, it avoids the inductor and magnetic-field concerns of a switching inductor converter. This is useful around sensitive amplifiers, data converters, sensor front ends, and instrumentation channels where supply noise can directly affect signal accuracy.

LTC3260HMSE#PBF is commonly used to power op amps, ADCs, DACs, bridge sensors, industrial measurement circuits, and portable analog instruments that need matched positive and negative rails from a compact single-IC solution.

Key Specifications

Pinout & Package

The LTC3260HMSE#PBF pinout includes input supply, flying-capacitor charge-pump pins, positive and negative regulated outputs, LDO setting or feedback nodes, control pins, and ground connections.

For PCB design, flying capacitors and reservoir capacitors should be placed close to the IC, while positive and negative LDO output capacitors should follow datasheet stability guidance to preserve low-noise operation.

Key Features

• Generates bipolar rails from a single positive supply.
• Charge-pump architecture avoids an inductor.
• Positive and negative LDO post regulation lowers output noise.
• Compact MSOP package supports dense analog boards.
• Useful for op amp and data-converter supplies.
• Shutdown control supports portable and low-power systems.

Applications

Equivalent & Alternatives

When evaluating a LTC3260HMSE#PBF equivalent, engineers should compare bipolar output capability, noise, LDO current, package, charge-pump capacitor requirements, and analog signal-chain performance.

Compared with LTC3260IMSE#TRPBF, LTC3260HMSE#PBF should be selected according to temperature, package, and ordering requirements. LTC3260HMSE#PBF vs TPS65133 selection depends on noise target, output current, topology preference, PCB area, and analog performance requirements.

Quality

LTC3260HMSE#PBF should be sourced as original Analog Devices components through traceable channels. Quality checks may include package inspection, top-mark validation, solderability testing, and bipolar output electrical verification.

Production validation should include positive and negative output accuracy, noise measurement, capacitor placement review, load response, shutdown behavior, and analog system performance testing.

Availability

LTC3260HMSE#PBF available at Aetrix Electronics and is suitable for precision analog, instrumentation, data-converter, sensor, and portable test equipment platforms.

Supply support may include volume procurement planning, scheduled delivery arrangements, traceable sourcing management, and long-term supply support for OEM, industrial electronics, automotive electronics, and embedded product programs.
