In summary, the LTC2379 family of SAR ADCs offers 101dB SNR at 18-bits of resolution. These pin- and software-compatible, 250ksps to 2Msps, high performance SAR ADCs, allow flexibility in designs to upgrade from a lower speed or resolution part or vice versa without changing the design and software. The Digital Gain Compression feature eliminates the need for a negative supply on the ADC driver, dramatically reducing the total power consumption of the signal chain. True zero power sampling and linear scaling of power dissipation makes the LTC2379 family a low power dissipating family. The user-friendly interface simplifies the interface and daisy chaining of multiple ADCs on a single SPI bus.
