Specifications
This section describes three classes of characteristics for the ADA400A
Differential Preamplifier: nominal, warranted, and typical.
Nominal Characteristics
Nominal traits are described using simple statements of fact such as “Differen-
tial, ‘+’ and ‘--’” for the characteristic “Input Configuration,” rather than in terms
of limits that are performance requirements.
Table 4: Nominal Characteristics — Signal Acquisition System
Name Description
Input Configuration Differential, ‘+’ and ‘--’
Input Coupling DC, AC, or GND
Ground coupling connects a ground reference to the input of the attenuator or
differential amplifier and allows the AC coupling capacitor to charge up to the
input voltage through a large resistance.
Gain Settings 0.1, 1, 10, 100
Analog Bandwidth Selections 100 Hz, 3 kHz, 100 kHz, and FULL (1 MHz)
