Part Details for TC7126ACKW713 by Microchip Technology Inc

Microchip recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital signals separate. Use short, direct traces for the analog inputs and outputs, and avoid running digital signals near the analog signals. Additionally, use a low-ESR capacitor for the VCC bypass and keep it close to the device.

Calibration involves adjusting the internal offset and gain of the device. Microchip provides a calibration procedure in the datasheet, which involves applying a known input voltage and adjusting the offset and gain registers to achieve the desired output code. It's recommended to perform calibration at multiple temperatures to ensure accuracy across the operating range.

The TC7126ACKW713 has an absolute maximum input voltage rating of 15V. Exceeding this voltage can cause permanent damage to the device. It's recommended to use input protection circuitry, such as voltage dividers or clamping diodes, to prevent overvoltage conditions.

The TC7126ACKW713 outputs data in a 12-bit, two's complement format. The output code can be scaled using the device's built-in gain and offset registers. Microchip provides a formula in the datasheet to convert the output code to a voltage reading. Additionally, the device has a built-in voltage reference, which can be used to simplify the scaling process.

The TC7126ACKW713 has a typical power consumption of 1.5mA at 5V. To reduce power consumption, use the device's power-down mode, which reduces the current consumption to 10uA. Additionally, consider using a lower supply voltage, such as 3.3V, and optimizing the device's sampling rate and conversion time to minimize power consumption.
