概览

The ISL71148SLH is a radiation hardened 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 programmable gain amplifier (PGA). The device 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 ISL71148SLH 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 device is available in a 48-lead thin quad flat-pack (TQFP) space plastic.

The ISL71148SLH offers a separate low-power mode (LPM) pin that reduces power dissipation at lower sample rates. An external reference with a supported input range of 2.4V to 2.6V determines the analog input signal range.
