描述

The ISL73148SEH is a radiation hardened, high-precision, 8-Channel 14-Bit 900/480ksps SAR analog-to-digital converter (ADC) with an integrated Programmable Gain Amplifier (PGA) that features an SNR of 83dBFS and dissipates only 90mW when operating from a 5V supply.

The product features 900kSPS throughput with no data latency and features excellent linearity and dynamic accuracy. The ISL73148SEH 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 integrated PGA has discrete gain steps of 1, 2, 3, 4, 6, 8, 12, and 16 and is controlled by external pin configurations.

The ISL73148SEH provides a separate power-down pin that reduces power dissipation to 115µW. The analog input signal range is determined by an external reference.

The ISL73148SEH 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.
