NATIONAL Semiconductor Corporation, represented by Arrow , has added five new 10- and 12-bit converters with low power consumption and strong dynamic performance to its range of high-speed analogue-to-digital converters (ADCs).
These ADCs are suitable for a variety of applications such as digital TV, high definition TV receivers, base station transceivers, communications receivers, data acquisition systems, medical imaging and consumer video.
CMOS manufacturing technology enables National Semiconductor to produce ADCs with good power savings.
The ADC10080 consumes only 78mW at 80MSPS. The ADC10065 consumes 68mW at 65MSPS and the ADC10040 consumes 55mW at 40MSPS.
The products feature a precision 1.2V internal reference, eliminating the need for an external reference.
Differential inputs on the ADCs provide a full-scale selectable input swing of 2Vpp, 1.5Vpp or 1Vpp, allowing flexibility in board design.
The ADCs also have a 400MHz - 3dB bandwidth, enabling their use in high-IF applications such as communications receivers.
All three products are pin-compatible.
The ADC12020 and ADC12010 are pin-compatible with National's existing 12-bit ADCs, the ADC12040, ADC12L063 and ADC12L066. This pin compatibility provides a straightforward migration path for designers, enabling reuse of existing printed circuit board designs on various platforms.
These 5V ADC12020 and ADC12010 consume only 185 mW at 20MSPS and 160mW at 10MSPS, respectively.
