Analog Devices Announces 12-Bit, 1.8 V, 500 MSPS Low-Power ADC with 660 mW Low Power Consumption

- The AD9434 solves heat generation issues with low power consumption of 660 mW while maintaining a consistent level of performance and speed, making it suitable for telecommunications and industrial applications.
- 8-bit ADC pin-compatible with AD9484 and AD9434

Analog Devices ( www.analog.com ), a global leader in high-performance semiconductors and a leader in the global data converter market, announced two data converters: the 'AD9434,' a low-power 12-bit 500 MSPS ADC that achieves a certain level of speed and performance with low power consumption, and the 'AD9484,' an 8-bit ADC that is pin-compatible with the AD9434. The AD9434 is characterized by consuming only 660 mW of power in an 8 mm x 8 mm LFCSP space-saving package, which solves heat-related issues and makes it suitable for low-power specifications in communications and industrial applications.

In addition, the AD9434 maintains a 65 dBFS signal-to-noise ratio (SNR) at a 500 MSPS sampling rate up to an input frequency of 250 MHz, meeting the requirements for small size and high dynamic range in addition to the low-power specifications needed for communication infrastructure, radar systems, data acquisition systems, and test and instrumentation applications. Furthermore, since the AD9434 is pin-compatible with the 12-bit 250 MSPS ADC 'AD9230', it can be easily replaced in various applications with minimal design modifications.

The AD9434 includes Sample-and-Hold, voltage reference, LVDS output, a single 1.8 V power supply, and an integrated data clock output with a programmable clock, allowing it to be used as a complete signal conversion solution. Additionally, the AD9434 provides flexibility for advanced Field-Programmable Gate Array (FPGA) products because the LVDS digital output data and output clock timing interfaces are user-programmable.

In addition, the AD9434 is the Analog Devices AD9523/24 low-jitter clock generator and ADL5562 ultra-low distortion RF/IF differential amplifier required for circuits in communication applications.
