Introduction
MODEL 2122 / 2122i
The Model 2122 is a differential amplifier for use with low-
BIOAMPLIFIER
level signals -- 2 microvolts and above -- ranging from DC
to 10 KHz. Primarily designed as biological
instrumentation, the Model 2122 is well suited to many
other demanding applications. It features high common-
mode rejection, high input impedance, low noise, small
size, and excellent frequency response. The Model 2122i
includes subject isolation, but is otherwise identical to the
standard Model 2122. A BioAmplifier Input Box with
convenient binding post terminals is an included accessory.
