Intersil Announces Industry's First Rad Tolerant 36V Instrumentation Amplifier with Integrated Differential ADC Driver

ISL70617SEH provides highest sensor signal processing performance for communication satellite applications

MILPITAS, Calif., July 11, 2016 — (PRNewswire) — Intersil Corporation (NASDAQ: ISIL), a leading provider of innovative power management and precision analog solutions, today introduced the industry's first radiation tolerant 36V instrumentation amplifier (in-amp) featuring an integrated differential analog-to-digital converter (ADC) driver. The high performance ISL70617SEH differential input, rail-to-rail output in-amp delivers the industry's highest signal processing performance for low-level sensor telemetry data critical to communication satellites. Its high integration and best-in-class performance reduces system size, weight and power (SWAP) costs, and accelerates time to market.

Intersil ships industry's first rad tolerant 36V instrumentation amplifier with integrated differential ADC driver. The ISL70617SEH provides highest sensor signal processing performance for communication satellite applications.

The ISL70617SEH enables higher common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) than the competition, at all gain settings. Designers can easily program the in-amp's gain from 0.1 to 10,000 using two external resistors. The device is wafer-by-wafer guaranteed to 75krad (Si) with a low dose rate exposure of 10mrad/sec, which more closely resembles the space environment than the high dose rate testing used with competitive devices. The ISL70617SEH leverages Intersil's proprietary silicon on insulator process to provide single event latch-up (SEL) and single event burnout (SEB) robustness of 60MeV in heavy ion environments. And its single event transient (SET) performance of <10usec eliminates the need for extra filtering.

The ISL70517SEH joins the ISL70617SEH, and offers similar features but implements a differential input and rail-to-rail single-ended output. Both in-amps allow designers to power the input/output stages from different supplies using individual power supply pins. Designers are able to take the input signals riding on a high common-mode voltage and level shift them to a low voltage device. For example, Intersil's in-amps can protect downstream ICs from high voltage signals by tying the amplifier's rail-to-rail output to an ADC's low voltage power supply. This also preserves the ADC maximum input dynamic range and eliminates ADC input overdrive.

"The ISL70617SEH is the space industry's first true differential-ended ADC driver," said Philip Chesley, senior vice president of Precision Products at Intersil. "This extends our portfolio of rad hard products exceeding the mission assurance needs of military and commercial communication satellites."

Key Features and Specifications of ISL70617SEH and ISL70517SEH

  • Low input offset of 30µV, and low input bias current of 0.2nA
  • Excellent CMRR and PSRR of 120dB typical for attenuating, gaining and filtering sensor signals to improve signal quality
  • Wide operating range from ±4V to ±18V covers the majority of analog supply rails
  • Closed loop -3dB BW 0.3MHz (AV = 1k) to 5.5MHz (A = 0.1)
  • Extended operating temperature range of -55°C to +125°C
  • Electrically screened to DLA SMD# 5962-15246
  • Acceptance tested to a higher dose level of 75krad(Si), wafer-by-wafer
  • Industry's lowest dose rate (0.01rad(Si)/s) radiation tolerance of 75krad(Si)
  • SEB LETTH (VS = ±18V) immune up to 60MeV•cm2/mg

The ISL70617SEH and ISL70517SEH can be combined with the ISL71830SEH 16-channel and ISL71831SEH 32-channel 5V multiplexers, ISL71590SEH temperature sensor, ISL71090SEH25 voltage reference, ISL75052SEH 1.5A LDO regulator, ISL75051SEH 3A LDO regulator, and op amps such as the ISL70444SEH, ISL70244SEH, ISL70417SEH, ISL70218SEH, ISL70227SEH, ISL70419SEH to support a telemetry signal chain with superior radiation tolerant performance.

Availability
The ISL70617SEH differential I/O instrumentation amplifier and ISL70517SEH single-ended instrumentation amplifier are available now in 24-lead ceramic flatpack packages.
