The ADS61JB46EVM (evaluation board) is an analog-to-digital converter (ADC) from Texas Instruments Inc. It is used in a variety of applications in the field of wireless and medical electronics, industrial process control, image and audio processing, and so on. The evaluation board helps designers to quickly and easily evaluate the performance of the ADC.

The ADS61JB46EVM is based on TI\'s dual-channel, low power, high speed, 12-bit ADC that is able to convert analog input signals from two different ranges (single-ended 0-1.3V or differential components up to 2.6V). It features an onboard instrumentation amplifier. The ADC provides up to 18 MSPS per channel with output data rate of up to 36 MSPS, with single-ended or differential inputs.

The evaluation board includes all the external components required to enable the ADC, including reference resistors, bypass capacitors, load resistors, filter capacitors, decoupling capacitors, power supply bypass capacitors, and through-hole jumpers. It also includes a USB interface, a signal generator, a calibration board, a power supply, and a BGA mounting bracket for development and debugging. Additionally, there is an onboard digital to analog converter (DAC) with a 16-bit output range, which is used for testing purposes.

The primary working principle of the ADS61JB46EVM is conversion of analog signals into digital signals. The analog input signals are first amplified by the instrumentation amplifier and then converted into 12-bit digital values. The digital values are then output from the ADC and can be read and monitored by a connected microcontroller. The board also includes analog filtering and noise suppression, allowing the ADC to provide high-resolution, low-noise digitization of analog input signals.

The board is ideal for applications that require high-resolution, low-noise digitization of audio and video signals. It is also well-suited for wireless and medical electronics, industrial process control, and image and audio processing. With the integrated DAC, the board can also be used for digital signal generation.

In summary, the ADS61JB46EVM is an evaluation board from Texas Instruments Inc. that is based on TI\'s dual-channel, low power, high speed, 12-bit ADC. It is used in a variety of applications, including wireless and medical electronics, industrial process control, and image and audio processing.
