Three external power supplies are required to operate the EB-TA2022: VPP, VNN (referenced to

Pgnd), and 5V (referenced to Agnd). The VPP and VNN form a split rail supply referenced to Pgnd.

The 5V ground (Agnd) must be kept separate from the VPP and VNN ground (Pgnd). Agnd and Pgnd

are joined at a common point on the EB-TA2022 near headers J2 and J3.

Minimum and Maximum supply voltages are +/-20V and +/-36V, respectively, depending on the load

impedance. It is not recommended that the EB-TA2022 be operated above +/-31V when driving 4Ω

loads, single ended, as the internal current limit circuit may activate, causing the amplifier to mute.

The VPP and VNN power supply connection, J3, is through a 7-Pin 0.156” spaced header. The

female terminal housing for this header is Molex 09-50-8071. Please see TABLE 2 for header

connections.

The 5V power supply connection, J2, is through a 5-Pin 0.100” spaced header. The female terminal

housing for this header is Molex 22-01-2057. Please see TABLE 1 for header connections.
