An electrostatic smock and safety glasses should also be worn. The ADS130E08EVM-PDK board is a four-layer circuit board. The board layout and schematics are appended to the end of this document. The ADS130E08EVM-PDK is configured to be used with the TI MMB0 data converter evaluation platform. The key features of the ADS130E08 system on a chip (SOC) are: • Eight integrated instrumentation amplifiers (INAs) and eight, 16-bit, high-resolution ADCs • Low power consumption • 3-V to 5-V unipolar or bipolar analog supply, and 1.8-V to 3.3-V digital supply • SPI data interface The following sections explain some of the hardware settings possible with the EVM for evaluating the ADS130E08 under various test conditions. 3.1 Power Supply The ADS130E08EVM mounts on the MMB0 board with connectors J1, J2, and J3. The main power supplies (+5 V, +3.3 V, and +1.8 V) for the front-end board are supplied by the host MMB0 board through connector J3. All other power supplies required for the front-end board are generated onboard by power management devices. The ADS130E08 operates in unipolar mode using a +3.0-V to +5.0-V analog supply (AVDD/AVSS) and a +1.8-V to +3.3-V digital supply (DVDD), or in bipolar mode using the onboard analog supply (±1.5 V to ±2.5 V). The power consumption of the front-end board is measured by using the JP3 jumper. Power down the ADS130E08 by shorting jumper JP4. Test points TP4, TP5, TP6, TP7, TP8, TP9, TP10, and TP13 are provided to verify that the host power supplies are correct. The corresponding voltages are shown in Table 1. Table 1. Power-Supply Test Points Test Point Voltage TP7 +5.0 V TP4 –4.96 V TP9 +1.8 V TP10 +3.3 V TP5 +3.0 V TP13 +2.5 V TP6 –2.5 V TP8 GND The front-end board must be properly configured in order to achieve the various power-supply schemes. The default power-supply setting for the ADS130E08EVM is a bipolar analog supply of ±2.5 V, and there are onboard options to switch to a unipolar analog supply of +3 V. The digital supply (DVDD) is selectable to either +3.3 V or +1.8 V. Table 2 shows the board and component configurations for each analog powersupply scheme. Table 3 shows the board configurations for the digital supply. Note that the EVM is shipped with the analog supply set to ±2.5 V and digital supplies set to 3.3 V.

This clock can vary by ±5% over temperature. For applications that require higher accuracy, the ADS130E08 can also accept an external clock signal. The ADS130E08 provides an option to test both internal and external clock configurations. It also provides an option to generate the external clock from either the onboard oscillator or from an external clock source. The onboard oscillator is powered by the DVDD supply of the ADS130E08. Care must be taken to ensure that the external oscillator can operate either with +1.8 V or +3.3 V, depending on the DVDD supply configuration. Table 4 shows the jumper settings for the three options for the ADS130E08 clocks. Table 4.

For a +1.8-V DVDD supply, use the SiT8002AC-34-18E-2.048. The EVM is shipped with the external oscillator enabled. 3.3 Reference The ADS130E08 has an on-chip internal reference circuit that provides reference voltages to the device. Alternatively, the internal reference can be powered down and VREFP can be applied externally. This configuration is achieved with the external reference generators (U2 and U3) and driver buffer. These components (U2, U3, and U4) must be installed by the user; they are not installed at the factory. The external reference voltage can be set to either 4.096 V or 2.5 V, depending on the analog supply voltage. Measure TP3 to make sure the external reference is correct and stable. The settings for the external reference is described in Table 5. This table assumes REF5025 is installed at U2 and REF5040 at U3. A low-noise amplifier like the OPA350 can be installed at U4.

Analysis→FFT Graph of Normal Electrode Configuration 5.3.1 Coherent Frequency Calculator The red box labeled 1 in Figure 27 shows the Coherent Frequency Calculator. Coherent sampling in an FFT is defined in Equation 3: NWINDOW fAIN = NTOTAL fSAMPLE where: • • • • fAIN = input frequency fSAMPLE = ADS130E08 sampling frequency NWINDOW = number of odd integer cycles during a given sampling period NTOTAL = number of data points (in power of 2) that is used to create the FFT. (3) If the conditions for coherent sampling can be met, the FFT results for a periodic signal are optimized. The ideal AIN frequency is a value that is calculated based on the sampling rate so that the coherent sampling criteria can be met.
