AD7322 is a 2-channel, 12-bit, 1 MSPS, successive approximation ADC. The AD7322 has a high-speed serial interface that can operate up to 1 MSPS data throughput rate. The AD7322 can handle true bipolar analog input signals. The bipolar ranges are software selectable by programming the on-board Range Register. Bipolar input ranges include ±10V, ±5V, ±2.5V. The AD7322 can also handle a 0 to 10 V unipolar input range, which is also software selectable. By setting the appropriate bits in the Range Register, each analog input channel can be independently programmed to one of the input ranges. The Analog Input Channels can be configured as Single-Ended, Fully Differential or Pseudo Differential. Dedicated Control Register bits are used to configure the Analog inputs. The AD7322 contains a Channel Sequencer, allowing automatic conversions between each analog channel.
The AD7322 is a 2-Channel, 12-Bit Plus Sign SAR ADC featuring true bipolar analog inputs. It supports software-selectable input ranges of ±10V, ±5V, ±2.5V, or 0 to 10V and can handle single-ended, fully differential, or pseudo-differential configurations.
The device operates at throughput rates up to 1 MSPS with a full power signal bandwidth greater than 13 MHz. It includes an internal 2.5 V reference but allows for external reference operation, consuming low power (6 mW typical) and offering various power-down modes.
