Analog Devices Introduces the ADA4930-1 and ADA4930-2 Ultra-Low-Noise ADC Drivers for 14-bit ADCs
Analog Devices introduced the ADA4930-1 and ADA4930-2 ultra-low-noise ADC drivers for 14-bit ADCs (analog-to-digital converters). The ADA4930-1 and ADA4930-2 ultra-low-noise ADC drivers are capable of driving dc to 1.35-GHz signals while consuming only 115 mW (milliWatts) of power and operating with a single supply.
The low-power and low-noise ADC drivers feature one of the industry’s lowest noise specification of 1.2 nV/rt-Hz and low distortion in the frequency range of 20 MHz to 100 MHz. The combination of low noise and low distortion ensures more accurate measurement and signal representation for 14-bit ADCs used in electronic test and measurement equipment, data acquisition systems, wireless direct-conversion receivers and other wideband applications with data throughput of 40 MSPS (million samples per second) to 200 MSPS.
The new ADC drivers feature a 0.9-V output common mode voltage and are ADI’s first single-supply ADC drivers capable of driving the input of a dc-coupled, 1.8-V ADCs all the way to ground. This eliminates the second voltage supply required by other ADC drivers and reduces cost, power use and board space. The ADA4930-2 dual-channel ADC driver works well with ADI’s AD9640 dual ADC, while the ADA4930-1 single-channel ADC driver is suited to operate with ADI’s AD9255 single ADC.
The sample of ADA4930-1 is availability now with temperature range -40°C to 105°C and 3 mm × 3 mm 16-lead LFCSP package. The sample of ADA4930- 2 is availability now with temperature range -40°C to 85°C and 4 mm × 4 mm 24-lead LFCSP package. The Price of ADA4930-1 and ADA4930- 2 are $3.78 and $6.29 each in 1000 quantities respectively.
