The maximum clock frequency for TLC549IDRG4 is 4 MHz. However, it's recommended to use a clock frequency of 1 MHz or less to ensure accurate conversions.
The TLC549IDRG4 has a built-in POR circuit that resets the device when the power supply voltage (VCC) rises above 1.5 V. To handle POR, ensure that the VCC ramp-up time is slower than 10 ms/V to prevent incorrect conversions.
To minimize noise and ensure accurate conversions, keep the analog and digital grounds separate, use a star-ground configuration, and keep the analog input traces short and away from digital traces. Also, use a bypass capacitor (e.g., 0.1 μF) between VCC and GND near the device.
The TLC549IDRG4 does not require calibration. It has an internal calibration circuit that ensures accurate conversions. However, to achieve the best possible accuracy, ensure that the device is operated within the recommended temperature range and that the input signals are within the specified voltage ranges.
The maximum input voltage range for TLC549IDRG4 is 0 V to VCC (typically 5 V). However, the device can handle input voltages up to 6 V without damage, but the accuracy may be affected.
