The ADS7279IPWR is a low-power, 14-bit analog-to-digital converter (ADC) from Texas Instruments, utilizing a successive approximation register (SAR) architecture. It achieves a maximum sampling rate of 1 MHz when the analog supply is between 3V and 5.5V, and 900 kHz when the analog supply is between 2.7V and 3V. The device features a single-ended unipolar input with an input voltage range of 0V to Vref, and requires an external voltage reference.
This ADC provides excellent DC performance with typical integral nonlinearity (INL) and differential nonlinearity (DNL) of ±0.4 LSB, and maximum values of ±1.0 LSB. AC performance at a 10 kHz input frequency 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. The device includes a built-in conversion clock and supports SPI/DSP-compatible serial interfaces with SCLK frequencies up to 50 MHz.
The ADS7279IPWR operates from an analog supply voltage of 2.7V to 5.5V and a digital I/O supply of 1.65V to 5.5V. Typical power consumption is 13.7 mW at 1 MHz sampling with +VA=3V and +VBD=1.8V. The device offers comprehensive power-down modes including deep power-down, nap power-down, and auto nap power-down for power-sensitive applications. It is available in a 16-pin TSSOP package and is specified for operation over the industrial temperature range of -40°C to 85°C.
Typical applications include communications, transducer interfaces, medical instruments, magnetometers, industrial process control, data acquisition systems, and automatic test equipment. The device also supports daisy-chain mode for multiple converter configurations and includes a software reset and global CONVST feature.
