Renesas Analog Signal Chain Solutions

Renesas' precision analog portfolio provides a wide range of next-gen precision instrumentation, medical, communication and industrial process control applications where innovation, reliability and dependability is central to the analog designs. Renesas' precision analog products are built on the latest technology; we offer a wide portfolio of general purpose analog building blocks targeted at precision signal chain design. With proven proprietary processes and package technologies, Renesas ships over one billion ICs per year with less than 1.2 DPPM (defective parts per million). Our strong technology development and multi-sourcing strategy from multiple leading-edge semiconductor foundries and assembly/test partners ensures a steady product supply with reduced risk.


Renesas offers industry-leading devices to enable efficient and reliable communication for industrial control, networking, and computing applications. Dual protocol transceivers, I2C Buffers, wide operating voltage range RS-232 transceivers, and RS-485/422 devices with the highest noise immunity and ESD protection in small packages are available to support high-speed data transfer and a variety of configurations to fit your application.

Digital Power Monitors

Renesas' ISL2802x digital power monitor (DPM) family delivers high accuracy measurements in a wide input common mode voltage range (0V to 60V), providing designers with the high level of safety margin that is often necessary in wired, wireless and data infrastructure applications.

  • The ISL28022 is a bidirectional high-side and low-side digital current sense and voltage monitor with serial interface.
  • The ISL28023 is a precision DPM that integrates the analog comparators, a voltage regulator, a DAC and a low voltage auxiliary channel in a single chip.
  • The ISL28025 is a high precision DPM with integrated analog comparators and an integrated voltage regulator.

Part Family

  • ISL28022: 0V to 60V, 10 Ld MSOP, 16 Ld QFN
  • ISL28023 : 0V to 60V or 0V to 12V, 24 Ld QFN
  • ISL28025: 0V to 60V or 0V to 12V, 16 Ld WLCSP

Precision Instrumentation Amplifiers (Programmable)


The ISL2853x and ISL2863x family of ultra-high precision instrumentation amplifiers (in-amps) feature zero-drift circuitry that provides auto offset voltage correction and noise reduction, delivering very low offset voltage drift of nV/°C and a low 1/F noise frequency corner down in the tens of mHz range. These in-amps integrate precision matched resistors for the front gain stage and the differential second stage, providing very high gain accuracy and excellent CMRR.

  • Zero-drift instrumentation amplifier
  • 9 pin selectable gain options: Av = 1 to 1,000
  • Rail-to-rail input/output
  • Single-ended output (ISL28533, ISL28534, ISL28535)
  • Differential output (ISL28633, ISL28634, ISL28635)
  • RFI filtered inputs improve EMI rejection
