ADC081500数据手册TI中文资料规格书

描述 Description

The ADC081500 is a low power, high performance CMOS analog-to-digital converter that digitizes signals to 8 bits resolution at sample rates up to 1.7 GSPS. Consuming a typical 1.2 W at 1.5 GSPS from a single 1.9 Volt supply, this device is ensured to have no missing codes over the full operating temperature range. The unique folding and interpolating architecture, the fully differential comparator design, the innovative design of the internal sample-and-hold amplifier and the self-calibration scheme enable a very flat response of all dynamic parameters beyond Nyquist, producing a high 7.3 ENOB with a 748 MHz input signal and a 1.5 GHz sample rate while providing a 10-18 B.E.R. Output formatting is offset binary and the LVDS digital outputs are compatible with IEEE 1596.3-1996, with the exception of an adjustable output offset voltage between 0.8V and 1.2V. The converter output has a 1:2 demultiplexer that feeds two LVDS buses and reduces the output data rate on each bus to one-half the sample rate. The converter typically consumes less than 3.5 mW in the Power Down Mode and is available in a 128-lead, thermally enhanced exposed pad HLQFP and operates over the Industrial (-40°C ≤ TA ≤ +85°C) temperature range.
