Analog Devices Inc. Analog Devices AD7329 12-Bit Plus Sign ADCs

Analog Devices AD7329 12-Bit Plus Sign Analog-to-Digital Converters (ADCs) are fast, 8-channel, plus sign successive approximation ADCs designed on the iCMOS™ (industrial CMOS) process. This process allows the AD7329 to accept true bipolar input ranges that include ±10V, ±5V, ±2.5V, and 0V to +10V while dramatically reducing power consumption. The designer can program a different analog input range on each analog input channel via the on-chip registers. The analog input channels on the AD7329 can be programmed to be single-ended, true differential, or pseudo-differential. AD7329's high-speed serial interface operates at throughput rates up to 1MSPS with a reduced power consumption of 21mW in a 24-lead TSSOP package.
