3PEAK – Analogue, Signal Chain, Interface & Power Management

3PEAK was founded in Shanghai back in 2012 and has since been dedicated to the development of analogue, signal-chain, interface, power, power-management and mixed-signal front-end ICs.

Today, over 1600 products are already available. In 9 development centres, almost 70% of the employees work in research and development. This is reflected in a well-filled roadmap for new products in the next 2 years.

Portfolio overview

The 3PEAK portfolio covers almost every area of an analogue signal chain, power supply, communication interfaces or driver ICs. The following diagram illustrates the different product groups

Analog, Signal-Chain, Interface & Power-Management Overview

Amplifiers (OPs)

It becomes immediately apparent how broad 3PEAK’s portfolio is. In the area of amplifiers, almost all types can be found, so that your developers can quickly find the right product based on the most important parameters, including many “classics” such as LM321, LM324, LM358, but also high-quality OPs optimised for zero-drift, low-noise, high-speed or high-voltage. Bidirectional zero-drift shunt measuring amplifiers or amplifiers with high common-mode voltage up to 285V can also be found in the portfolio.


In the field of converters, both high sampling rates (up to 50 Msps @ 10 bit) and high resolution (up to 24 bit @ 4ksps) are offered. The ADCs and DACs are complemented by combined ADC/DACs.

Analogue front-ends with e.g. 8 channels (16 bit @ 1 Msps), with +/-10V bipolar inputs as well as PGA and intelligent pre-processing (filter) complete the product range.

Interface ICs

3PEAK offers transceivers for widely used interfaces such as RS485, RS422, RS232 or CAN. For applications requiring electrical isolation, various digital isolator ICs are available for transmission rates up to 100Mbit/s at 5kVrms and CMTI>150kV/µs. Currently 3PEAK is working on the combination of transceivers and isolators.

Power supply & monitoring

For the power segment, LDOs are available either with Vin up to 42V or Iout up to 3A as well as Buck-DC/DC converters for up to 60V@5A.

Voltage supervisor ICs with and without watchdog function are available with different reset thresholds. Also available: precision shunt regulators compatible with the TL431 as well as voltage references with 0.15% accuracy, 30ppm/°C drift and low output noise (e.g. 50µVpp at Vout=2.5V) for an operating temperature range from -40 to 125°C.

Driver ICs

Full-bridge motor drivers up to 17V / 1A, low-side gate drivers (for MOSFETs/IGBT) as well as 7 / 8 channel low-side switch arrays (ULN2003 compatible) form the final part of the product range.

In addition to the products currently available for industrial applications, the first automotive qualified ICs are available as well as many more on the current roadmap.

We would be happy to advise you on Analog, Signal-Chain, Interface & Power-Management parts from the 3PEAK product portfolio for your next product development or find suitable available alternative components for already finished designs.
