ADS7039-Q1 - Ultra-Low-Power Ultra-Small-Size 10-Bit 2MSPS SAR ADC

The ADS7039-Q1 device is a an automotive Q100-qualified,10-bit, 2-MSPS, analog-to-digital converter (ADC). The device supports awide 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. TheSPI-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 forconversion and serial data output. The device supports a wide digital supply range (1.65 V to 3.6V), enabling direct interface to a variety of host controllers. The ADS7039-Q1complies with the JESD8-7A standard for a normal DVDD range (1.65 V to 1.95 V).

The ADS7039-Q1 is available in an 8-pin, miniature, VSSOP package andis specified for operation from –40°C to +125°C. The fast sampling rate of theADS7039-Q1, along with miniature form-factor and low-power consumption, makesthis device suitable for space-constrained and fast-scanning automotive applications.
