Texas Instruments ADS7049-Q1 | Demoboard ADS7049-Q1EVM

Description

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).
