PRODUCTION DATA
The device has two analog-to-digital converters (ADCs): a primary ADC and a secondary ADC. The primary ADC features a 16-channel multiplexer, an on-chip track-and-hold, and a successive approximation register (SAR) ADC based on a capacitive digital-to-analog converter (DAC). This ADC runs at 500 kSPS and converts the analog channel inputs, CH0 to CH15. The analog input range for the device can be selected as 0 V to VREF or 0 V to (2 × VREF). The analog input can be configured for either single-ended or differential signals. The device has an on-chip 2.5-V reference that can be disabled when an external reference is preferred. If the internal ADC reference is to be used elsewhere in the system, the output must first be buffered. The various monitored and uncommitted input signals are multiplexed into the ADC. The secondary ADC is a part of the temperature-sensing function that converts the analog temperature signals.
