The PCM1690DCAR is an application-specific integrated circuit (ASIC) designed specifically to meet the needs of the automotive industry. This device features an integrated digitally-controlled potentiometer, multiple analog-to-digital (ADC) converters, and a digital-to-analog (DAC) converter. The PCM1690DCAR is designed to provide an accurate and cost-effective solution for automotive applications that require analog signal conditioning.

The PCM1690DCAR is primarily used for signal conditioning and monitoring of automotive systems, including body control functions such as the speed of transmission, brake lights, and fuel injection. Automotive engineers use the PCM1690DCAR to measure and monitor the state of the system. The device is useful for applications requiring precision analog-to-digital conversion, or for providing feedback control.

The PCM1690DCAR implements a 12-bit, single-slope ADC that utilizes a differential parallel-array architecture. This architecture minimizes power consumption and reduces the device’s size, while achieving high speed and accuracy. Additionally, the PCM1690DCAR features a 16-bit digital-to-analog converter (DAC) that can be used to control the system’s output voltage. This allows the user to accurately set and fine-tune the output voltage.

The PCM1690DCAR also features an integrated precision reference, preventing power supply fluctuations and temperature drift. The differential current source architecture helps to provide high accuracy and immunity to noise and other environmental variations. Additionally, the integrated programmable gain amplifiers allows the user to optimize the dynamic range and achieve better accuracy.

The device also includes an integrated voltage comparator, which is used to compare the output voltage of the DAC to the reference voltage or a secondary input voltage. This allows the user to monitor the system’s state, as well as to detect any changes in output voltage. Additionally, the device features an integrated multiplexer, which is used to connect multiple analogue inputs to the ADC.

Overall, the PCM1690DCAR is an excellent choice for automotive applications that require precision ADC and DAC functionality. It features several integrated functions, such as the reference voltage, voltage comparator, and multiplexer, which make it an ideal solution for automotive system monitoring and control. Additionally, the device’s small size and low power consumption make it well suited for automotive applications.
