A data-acquisition ASIC for medical implants is composed of a microcontroller and three programmable analog channels. The 85mm2 die with 75k transistors fabricated in 1.6 micro meter CMOS operates from 2.5 to 5V. 1 micro V/square root Hz equivalent channel input noise is obtained with 3.9mW power dissipation.
