iA4 – Differential Amp Module
The iA4 is a precision, four-channel amplifier module for the iCon platform. The iA4 module is built with the time-proven and direct-digital amplifier circuits pioneered by TDT. The iA4 employs true differential amplification and isolated high-resolution digitization to provide extremely low noise recordings for sleep and epilepsy research.
The iA4 is fully integrated into Synapse with features like frequency response controlled via software. Built-in impedance checking supports scanning electrode impedance via the Synapse software or with the push of a button on the device’s front panel.
When used with an iConZ, the iA4 can be connected to a laptop via USB3 for a low-cost portable recording system.
