Bandpass IF subsystem ADC — key parametrics
The AD6140ARSRL is a bandpass IF subsystem ADC from Analog Devices, part of the AD6140 series. It uses a sigma-delta architecture with a single-ended input and a single converter channel. Both the analog and digital supply rails are specified at 2.5 V to 2.9 V, so the same rail can feed both sides — simplifying the power tree in a mixed-signal IF chain. The reference type is external, meaning the ADC's full-scale range is set by an external voltage reference — a design detail that matters when matching the ADC span to the IF signal amplitude.
Lifecycle and compliance
RoHS status is non-compliant — verify the assembly house's exemption policy if the BOM requires full RoHS conformance.
