ISL71830SEH DATASHEET ISL70517SEH FN8699 Rev 5.00 36V Radiation Hardened Precision Instrumentation Amplifier with Rail-to-Rail Jan 28, 2021 Output ADC Driver The ISL70517SEH is a high performance, differential input, Features single-ended output instrumentation amplifier designed for Rail-to-rail single-ended output ADC driver precision analog-to-digital applications. It can operate over a supply range of 8V (4V) to 36V (18V) and features a Low input offset .30V differential input voltage range up to 30V. The output stage Input bias current . 0.2nA has rail-to-rail output drive capability optimized for ADC driver Excellent CMRR and PSRR 120dB applications. The output stage is powered by separate supplies. This feature enables the output to be driven by the Wide operating voltage range . 4V to 18V same low voltage supplies powering the ADC, thereby Closed loop -3dB BW 0.3MHz (A = 1k) to 5.5MHz (A =0.1) V V providing protection from high voltage signals and low voltage digital circuits. Its versatility makes it suitable for a variety of Operating temperature range -55C to +125C general purpose applications. Additional features not found in Electrically screened to DLA SMD 5962-15246 other instrumentation amplifiers enable high levels of DC Radiation acceptance testing precision and excellent AC performance. - Low dose rate (0.01rad(Si)/s) 75krad(Si) The gain of the ISL70517SEH can be programmed from 0.1 to SEE hardness (see SEE report for details) 10,000 via two external resistors, R and R . The gain IN FB 2 - SEB LET (V = 18V) . 60MeVcm /mg TH S accuracy is determined by the matching of R and R . The IN FB gain resistors have Kelvin sensing, which removes gain error Applications due to PCB trace resistance. The input and output stages have individual power supply pins, which enable input signals riding ADC driver on a high common-mode voltage to be level-shifted to a low Precision test and measurement voltage device, such as an A/D converter. The rail-to-rail output High voltage process control stage can be powered from the same supplies as the ADC, which preserves the ADC maximum input dynamic range and Signal conditioning for remote powered sensors eliminates ADC input overdrive. Satellite communication The ISL70517SEH is offered in a 24 Ld ceramic flatpack package with an operating temperature range of -55C to Related Literature +125C.
