Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital grounds separate. The analog input traces should be kept short and away from digital traces. Additionally, the decoupling capacitors should be placed close to the device.
The internal reference voltage of the TLV5636CDR is 2.5V, but it can be bypassed using an external reference voltage between 2.5V and 5V. The external reference should be connected to the REF pin, and the internal reference should be disabled by connecting the REFIN pin to GND.
The maximum sampling rate of the TLV5636CDR is 1 MSPS, and it affects the power consumption. At higher sampling rates, the power consumption increases. The device consumes around 15mW at 1 MSPS, and around 5mW at 100 kSPS.
The TLV5636CDR can be interfaced with a microcontroller using the SPI or I2C protocol. The device has a 3-wire SPI interface, and the I2C interface is compatible with standard I2C protocols. The recommended communication protocol is SPI, as it provides faster data transfer rates.
The TLV5636CDR has a typical accuracy of ±1 LSB, and a linearity of ±0.5 LSB. This means that the device can provide accurate conversions with minimal non-linearity errors. The accuracy and linearity of the device affect the overall system performance, and can impact the precision of the measurements.
