Reccomendations for AD7731 replacement

Hello all,


Our design was initially using the AD7731 ADC (in 16bit mode). The design has been updated and no longer requires multiple differential channels.

We now only require 1 differential channel.

Any recommendations for a low noise ADC replacement?


Something around 20sps or faster


We are using the AD7731 in differential mode

(+/- 1.28V bipolar, Buffered inputs, +2.5v ref on - differential input, 5v DC, 5v DC AREF+ and GND for AREF-, CHOP enabled, SKIP Disabled, FAST Disabled.)


Hope that is enough information.
