The ADS7279IRSAR is a low-power, 14-bit analog-to-digital converter (ADC) from Texas Instruments using successive approximation register (SAR) architecture. It offers a maximum sampling rate of 1 MHz and accepts a single-ended unipolar input voltage range of 0 V to 5.5 V. The ADC is controlled via an SPI/DSP-compatible serial interface with a clock rate up to 50 MHz and includes a built-in conversion clock (CCLK) for simplified timing.
Key electrical performance includes a signal-to-noise ratio (SNR) of 85.9 dB, spurious-free dynamic range (SFDR) of 105.3 dB, and total harmonic distortion (THD) of -100.1 dB, measured at 10 kHz input frequency. The device consumes only 13.7 mW typical power at 1 MHz sampling with 3 V analog and 1.8 V digital supplies. It features a daisy-chain mode, programmable status/polarity end-of-conversion (EOC) signal, and multiple power-down modes (deep power-down, nap, and auto nap).
The ADS7279IRSAR is specified for the industrial temperature range of -40°C to 85°C and is available in a 16-pin VQFN with exposed pad (4 mm × 4 mm) package for surface-mount assembly. It is suitable for applications requiring high-resolution, low-power data acquisition such as communications transducers, medical instruments, and industrial process control.
