ISL71148M - Radiation Tolerant 8-Channel 14-Bit 900/480ksps SAR ADC

General Description

The ISL71148M is a radiation tolerant 8-channel high precision 14-bit, 900/480ksps SAR Analog-to-Digital Converter (ADC).

The ADC core is preceded by eight fully differential analog input channels, a buffered 8-to-1 multiplexer, and a PGA (Programmable Gain Amplifier).

Key Features

  • a peak SNR of 83.2dBFS when operating at 900ksps. With the PGA enabled, sampling rates up to 480ksps are supported. The PGA can be bypassed to increase the sample rate to 900ksps. The product features 900/480ksps throughput with no data latency, excellent linearity, and dynamic accuracy. The ISL71148M offers 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 ISL71148M offers a separate low-power mode (LPM) pin t.
