Product Summary

The AT84AD001BVEPW is a monolithic dual 8-bit analog-to-digital converter, offering low 1.4W power consumption and excellent digitizing accuracy. The AT84AD001BVEPW integrates dual on-chip track/holds that provide an enhanced dynamic performance with a sampling rate of up to 1 Gsps and an input frequency bandwidth of over 1.5 GHz. The dual concept, the integrated demultiplexer and the easy interleaving mode make this device user-friendly for all dual channel applications, such as direct RF conversion or data acquisition. The smart function of the 3-wire serial interface eliminates the need for external components, which are usually necessary for gain and offset tuning and setting of other parameters, leading to space and power reduction as well as system flexibility. The applications of the AT84AD001BVEPW include Instrumentation, Satellite Receivers, Direct RF Down Conversion, WLAN.
