Gigahertz 14-bit ADC eases direct conversion RF

May 26, 2016 // By Peter Clarke
Texas Instruments has introduced a 14-bit analog-to-digital converter (ADC) that runs at up to 3-gigasamples per second and priced at $2,495.00

This dual-channel ADC, the ADC32RF45 enables direct RF signal conversion up to 4GHz and can eliminate up to four intermediate-frequency down-conversion stages in multiband receivers if users shift to direct down conversion.

Direct RF sampling meets engineers' requirements for higher integration, better noise performance, wider bandwidth and smaller footprints in radar, software-defined radio, aerospace and defense, test and measurement, wireless communication, and radio astronomy systems.

The ADC32RF45 offers a signal-to-noise ratio of 58.5 dB at a 1.8-GHz input frequency.

TI is offering an evaluation module for the part, the ADC32RF45EVM, priced at $2,499.00.

The ADC32RF45 will be in volume production in the third quarter of 2016 in a 72-pin, 10mm by 10mm quad flat no-lead (QFN) package for US$2,495 in 100-unit quantities.
