An IC for acquisition of 16 electrophysiology signals in mice is described. Each channel includes programmable gains from 10 to 1000, a 7 kHz low-pass 4th-order Butterworth filter and a sample and hold. Simulations predict 14-bit accuracy up to 7 kHz. The integrated noise from 1 Hz to 7 kHz is 1.9 /spl mu/V/Hz/sup 1/2 /. The +/-0.3V dc input offset of each channel is cancelled with 7-bit DACs controlling the bulk of the first opamp input transistors and 6-bit DACs on the 2/sup nd/ stage. Total power dissipation is 13.5 mW using a 3V supply. Die area is 6 mm/sup 2/ in a 0.25 /spl mu/ process.
