Overview

Description

The ISL73141SEH is a radiation hardened, high-precision, 14-bit, 1MSPS SAR analog-to-digital converter (ADC) that features an SNR of 82.1dBFS and dissipates only 60mW when operating from a 5V supply. With a 3.3V supply, the ISL73141SEH operates at 750KSPS with a power consumption of 28mW.

The product features 1MSPS throughput with no data latency and features excellent linearity and dynamic accuracy. The ISL73141SEH provides a high-speed SPI-compatible serial interface that supports logic ranging from 2.2V to 3.6V using a separate digital I/O supply pin.

The ISL73141SEH provides a separate power-down pin that reduces power dissipation to <50µW. The analog input signal range is determined by an external reference.

The ISL73141SEH operates across the military temperature range from -55 °C to +125 °C and is available in a 14Ld hermetically sealed Ceramic Dual Flat-Pack (CDFP) package.
