AC6801 targets configurable and ultra-low power consumption, while not compromising precision and accuracy. This chip is equipped with a 24bit sigma-delta ADC to achieve high accuracy while performing DC measurements while maintaining a current consumption of less than 1mA.
AC6801 also comes with a fully-integrated Time of flight signal chain. This includes a programmable gain amplifier, AC amplifier, phase detectors, and This allows for a very integrated solution for TOF based applications, requiring very few external components. Also, there are 2 general-purpose operational amplifiers for applications that require 5mA and 8mA maximum driving strength.
