May 18, 2010
12-Bit, Single 3.6 GSPS ADC
1.0 General Description
The 12-bit, 3.6 GSPS ADC12D1800 is the latest advance in
National's Ultra-High-Speed ADC family and builds upon the
features, architecture and functionality of the 10-bit GHz fam-
ily of ADCs.
The ADC12D1800 provides a flexible LVDS interface which
has multiple SPI programmable options to facilitate board de-
sign and FPGA/ASIC data capture. The LVDS outputs are
compatible with IEEE 1596.3-1996 and supports pro-
grammable common mode voltage.
The product is packaged in a leaded or lead-free 292-ball
thermally enhanced BGA package over the rated industrial
temperature range of -40°C to +85°C.
