AD7949 Datasheet (Analog Devices)

AD7949, 250 kSPS PulSAR ADC

The AD7949 is an 8-channel, 14-bit, charge redistribution successive approximation register (SAR) analog-to-digital converter (ADC) that operates from a single power supply, VDD.

The AD7949 contains all components for use in a multichannel, low power data acquisition system, including a true 14-bit
