Analog Devices AD7322 Manuals

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.

AD7322 is a 12-bit plus sign SAR ADC with true bipolar input ranges, software-selectable input ranges ±10 V, ±5 V, ±2.5 V, 0 V to +10 V, 1 MSPS throughput rate, two analog input channels with channel sequencer, single-ended, true differential and pseudo differential analog input capability, high analog input impedance, low power: 21 mW, full power signal bandwidth: 22 MHz, internal 2.5 V reference, high speed serial interface, power-down modes, 14-lead TSSOP package, iCMOS process technology.

The AD7322 is a 12-bit successive approximation analog-to-digital converter (ADC) with high integration, low power, and high performance. The AD7322 is fabricated using iCMOS technology and packaged in a 14-lead TSSOP. The AD7322 features a 12-bit resolution and a maximum conversion rate of 1 MSPS. The AD7322's input range is ±10 V, ±5 V, ±2.5 V, and 0 V to +10 V. The AD7322 also supports single-ended, true differential, and pseudo differential input configurations. The AD7322 provides an internal 2.5 V reference voltage and offers bandwidth up to 22 MHz.
