AD7417ARZ Datasheet PDF - ADI

The AD7417 series 10-bit 4-channel Analogue to Digital Converer (ADC) with an on-chip temperature sensor. The devices contain a 15µs successive approximation converter, a 5-channel multiplexer, a temperature sensor, a clock oscillator, a track-and-hold and a reference (2.5V). The temperature sensor on the parts can be accessed via multiplexer Channel 0. On-chip registers can be programmed with high and low temperature limits and an open-drain over-temperature indicator (OTI) output is provided, which becomes active when a programmed limit is exceeded. A configuration register allows programming of the sense of the OTI output (active high or active low) and its operating mode (comparator or interrupt). A programmable fault queue counter allows the number of out-of-limit measurements that must occur before triggering the OTI output to be set to prevent spurious triggering of the OTI output in noisy environments.

● On-chip track-and-hold

● Automatic power-down at the end of a conversion

● I²C-compatible serial interface selectable serial bus address allows connection up to 8
