Features

The CDK1308BILP40 features an on-chip oscillator, high-speed conversions, low-power modes of operation, and up to 12 channels of input, providing features such as:

• 8-channel, 12-bit analog-to-digital conversions
• Integrated voltage reference, programmable gain amplifier
• On-chip oscillator for up to 125 kSPS operation
• Low-power operation and sleep mode
• Input range from 0V to 2.5V
• Wide operating temperature range from -40°C to 125°C

Working Principle

The CDK1308BILP40 works on the principle of successive approximation. It provides an on-chip oscillator that generates clock pulses, which set the conversion rate up to 125ksps. The successive approximation register (SAR) is then used to convert analog input voltages into digital values.

The SAR works by comparing the analog input voltage to a reference voltage, and then storing the result of the comparator in a digital code. This process is repeated until all the digital bits have been set. The output of the SAR is a 12-bit digital code, which corresponds to an analog input voltage.

The CDK1308BILP40 also features an integrated voltage reference and programmable gain amplifier, which allows users to optimize the performance of the device. The voltage reference and PGA can be adjusted to both increase accuracy and reduce power consumption.

The device also features low-power modes of operation, allowing users to reduce power consumption when the device is not in use. This is especially useful for battery-powered applications, as it extends battery life.
