Hello, I'm Anthony Vaughan with Texas Instruments Precision Analog Marketing team. Today, I'm going to give you a quick overview of the features and resources available that make TI's line of Precision SAR ADCs well-suited for a wide variety of automotive and transportation applications. We have a rapidly expanding portfolio of SAR ADCs that are AEC Q100 qualified and specified for operation between negative 40 and 125 degrees Celsius.
This allows ADCs to be used in a multitude of vehicle locations, including in cabin and out. Some of the most popular areas these ADCs are used in today include infotainment systems, instrument clusters, advanced driver assistance systems, powertrain sensors, in addition to electric and hybrid electric vehicle battery monitoring.
For automotive applications, you can't beat the ADS795x family of multi-channel SAR ADCs. This 1 mega sample per second family has multiple resolution and input channel options, making it well-suited for a wide variety of voltage monitoring and sensor applications. Resolution options vary between 8 to 12 bits. And input channel options range between 4 to 16 multiplex channels.
One unique feature of this device family is the MUX output and the input to the ADC are both available on external pins. Only a single external amplifier is required for all input channels. The programmable alarm feature enables two separate thresholds to be set on each channel, useful for monitoring fault conditions. In addition, four general purpose input-output pins are individually configurable and controllable via the device's SPI port.
There are a number of online sources to help you get started on your automotive design. The TI Designs Precision page features several reference designs that accelerate the development of a system. The E2E support forum is a comprehensive online resource, where you can browse technical content and find the latest news and announcements about TI SAR ADCs.
Also, a team of applications engineers actively support questions posted on this forum. For more information about Precision SAR ADCs or to order a development kit, visit the TI Precision SAR web page at ti.com/precisionadc. Thank you for watching.
