ADC12D1600RFIUT Analog to Digital Converters - ADC 12B 2.0/3.2 GSPS RF sampling ADC Data Converter ICs

Description

The 12-bit 3.2- and 2-GSPS ADC12D1x00RF is an RF-sampling GSPS ADC that can directly sampleinput frequencies up to and

above 2.7 GHz. The ADC12D1x00RF augments the very large Nyquist zoneof TI’s GSPS ADCs with excellent noise and linearity

performance at RF frequencies, extending its usablerange beyond the 3rd Nyquist zoneThe ADC12D1x00RF provides a flexible

LVDS interface which has multiple SPI programmable options tofacilitate board design and FPGA/ASIC data capture.

The LVDS outputs are compatible with IEEE 1596.3-1996 and supports programmable common-mode voltage. The product is

packaged in a lead-free 292-ballthermally enhanced BGA package over the rated industrial temperature range of –40°C to 85°C.
