Beschreibung von ADS7049-Q1
The ADS7049-Q1 device is a an automotive Q100-qualified, 12-bit, 2-MSPS, analog-to-digital converter (ADC). The device supports a wide analog input voltage range (2.35 V to 3.6 V) 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 (1.65 V to 3.6 V), enabling direct interface to a variety of host controllers. The ADS7049-Q1 complies with the JESD8-7A standard for a normal DVDD range (1.65 V to 1.95 V).
The ADS7049-Q1 is available in an 8-pin, miniature, VSSOP package and is specified for operation from –40°C to +125°C. The fast sampling rate of the ADS7049-Q1, along with miniature form-factor and low-power consumption, makes this device suitable for space-constrained and fast-scanning automotive applications.
