8-bit SAR ADC in 18-SOIC
The ADC908FS is an 8-bit successive-approximation (SAR) ADC from Analog Devices, part of the ADC-908 series. It accepts a single differential input and presents conversion results through a serial data interface.
Parametric fit and supply rails
The 8-bit resolution with SAR architecture delivers a conversion latency that is cycle-deterministic — the serial output timing is predictable without pipeline delay, which matters for control-loop or multiplexed-input applications where sample-to-sample timing must be consistent. The external reference input (Reference Type: External) lets the user set the full-scale range independently of the supply voltage.
Note that this part is listed as RoHS non-compliant. For builds that require RoHS conformance, a lead-free alternative from the same functional family should be qualified during the design phase.
