具有 SPI 接口的 12 位 1MSPS 超低功耗、超小型 SAR ADC 8-VSSOP -40 to 125
The ADS7042 is a 12-bit, 1-MSPS, analog-to-digital converter ADC. The device supports a wide analog input voltage range 1.65 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 ADS7042 complies with the JESD8-7A standard for normal DVDD range 1.65 V to 1.95 V.
The ADS7042 is available in 8-pin, miniature, leaded, and X2QFN packages and is specified for operation from –40°C to 125°C. Miniature form-factor and extremely low-power consumption make this device suitable for space-constrained, battery-powered applications.
