RB-TK2051 6 CHANNELREFERENCE
POWER SUPPLIES
Two external power supplies are required to operate the RB-TK2051: VCC (referenced to GND), and V5 (referenced to G5). The V5 ground (G5) must be kept separate from the VCC ground (GND). GND and G5 are joined at a common point on the EB-TK2051 with a 0 resistor (R1). The Minimum and Maximum VCC supply voltages are +10V and +30V, respectively. The V5 supply voltage is 5V. Please see the TK2051 Data Sheet for Minimum and Maximum values. The VCC and V5 power supply connection is a standard 4-pin .156" Molex header (JP4). Please refer to the Board Connection Diagram for the connector locations on the EB-TK2051.
OUTPUT
The output connections for each channel of the RB-TK2051 are made with standard 4-pin .156" Molex headers (JP1, JP3, JP4). The output of the TK2051 is differential; therefore each output has a positive output (OUT_+) and a NEGATIVE OUTPUT (OUT_-). Please refer to the Board Connection Diagram for the connector locations on the RB-TK2051.
INPUT
The input connections of the RB-TK2051 are made with a standard 7-pin .100" Molex header (J1). There are six inputs and one common Agnd. Please refer to the Board Connection Diagram for the connector locations on the RB-TK2051.

Technical Information
JUMPER SETTINGS
There is a 3-pin header for the MUTE control of the TK2051. With the jumper placed in the G5 position the system is un-muted. When the jumper is placed in the V5 position the mute pin is pulled high (5V) and the amplifiers are muted. Please refer to the Board Connection Diagram for the connector locations on the RB-TK2051.
OUTPUT OFFSET NULL
There are six potentiometers that are used to manually trim the output offset to 0Vdc. Please refer to the Board Connection Diagram for the potentiometer locations on the RB-TK2051. The Evaluation board is shipped with the offsets nulled within +/-10mV.
GAIN SETTING
The gain of the RB-TK2051 Rev 2.2 is set to 15V/V. The gain of the TK2051 is the product of the TC2000 (control stage) gain and the TP2051 (power stage) gain. The control stage gain is set to unity. Before changing the gain of the RB-TK2051, please refer to the Amplifier Gain section of the TK2051 Data Sheet.
Performing Measurements on the EB-TK2051 Rev 1.3:
The TK2051 operates by generating a high frequency switching signal based on the audio input. This signal is sent through a low-pass filter that recovers an amplified version of the audio input. The frequency of the switching pattern is spread spectrum in nature and typically varies between 100kHz and 1MHz, which is well above the 20Hz - 20kHz audio band. The pattern itself does not alter or distort the audio input signal, but it does introduce some inaudible components. The measurements of certain performance parameters, particularly noise related specifications such as THD+N, are significantly affected by the design of the low-pass filter used on the output as well as the bandwidth setting of the measurement instrument used. Unless the filter has a very sharp roll-off just beyond the audio band or the bandwidth of the measurement instrument is limited, some of the inaudible noise components introduced by the TK2051 amplifier switching pattern will degrade the measurement by including out of band (audio) energy. One feature of the TK2051 is that it does not require large multi-pole filters to achieve excellent performance in listening tests, usually a more critical factor than performance measurements. Though using a multi-pole filter may remove high-frequency noise and improve THD+N type measurements (when they are made with wide-bandwidth measuring equipment), these same filters degrade frequency response. The RB-TK2051 has a simple two-pole output filter with excellent performance in listening tests. (See Application Note 4 for additional information on bench testing)
