ADC is ideal for space-constrained and fast-scanning automotive applications

The ADS7029-Q1 device, from Texas Instruments, is an automotive Q100-qualified, 8-bit, 2-MSPS, analog-to-digital converter (ADC). The device supports a wide analog input voltage range (2.35V to 3.6V) and includes a capacitor-based, successive-approximation register (SAR) ADC with an inherent sample-and-hold circuit. The SPI-compatible serial interface is controlled by the CS and SCLK signals. The input signal is sampled with the CS falling edge and SCLK is used for conversion and serial data output. The device supports a wide digital supply range (1.65V to 3.6V), enabling direct interface to a variety of host controllers. The device complies with the JESD8-7A standard for a normal DVDD range (1.65V to 1.95V). The device is available in an eight-pin, miniature, VSSOP package and is specified for operation from –40C to +125C. The fast sampling rate of the device, along with miniature form-factor and low-power consumption, makes this device suitable for space-constrained and fast-scanning automotive applications.
