Friday, June 07, 2013: Texas Instruments has launched a family of 12-bit, 500- to 900-MSPS analog-to-digital converters (ADCs). According to the company, these reduce board space by 80 per cent while providing industry-leading signal-to-noise ratio (SNR) and spurious-free dynamic range (SFDR).
The ADS5409 family provides best-in-class performance in a smaller footprint and at the lowest power consumption to meet the size, power and performance needs of test and measurement equipment, wideband LTE and LTE-advanced communications base stations, millimeter wave backhaul (v-band and e-band), cable infrastructure return path and defense electronics, the company added.
Wideband LTE and LTE-advanced power amplifier linearization previously required large, expensive and high-power-consumption feedback ADCs for speeds greater than 500 MSPS. The ADS5409 family addresses these challenges by reducing IC size, cost and power, while providing the high performance needed to achieve transmit spectral mask requirements and improved power amplifier efficiency.
The pin-compatible ADS5409 family includes six 1- and 2-channel ADCs at a variety of speed grades and price points to meet system needs.
Also new to the market, the complementary 12-bit ADS54T02 family includes three 1- and 2-channel, 500- to 750-MSPS dual-mode feedback and receiver ICs for time division duplex (TDD) base stations. The devices are pin-compatible with the ADS5409 family.
