Description

The AD7658BSTZ-1 is an Analog-to-Digital Converter (ADC) that falls under the category of Electronic Components. It is a reduced decoupling pin and software-compatible version of AD7658 and contains six fast, low power successive approximation ADCs. These ADCs are true bipolar analog inputs that have pin and software-selectable ranges of ±10 V and ±5 V. The ADCs provide a fast throughput rate of 250 kSPS and use the iCMOS process technology. The device comes with an on-chip reference and reference buffers and provides high-speed parallel, serial, and daisy-chain interface modes.
