AD7134, built-in anti-aliasing up to 102dB
Simplify isolation with an asynchronous sample rate converter


Conventional precision data acquisition signal chain design was time-consuming because it required balancing passive component tolerances, phases, and gain errors based on high-speed analog-to-digital converter (ADC) driving and anti-aliasing filter requirements.

Analog Devices (ADI) announced on the 21st that it has released the AD7134 alias-free analog-to-digital converter (ADC), which simplifies front-end design for precision DC-350kHz applications and accelerates product launch.

The AD7134 is a 4-channel, 24-bit precision ADC capable of scaling output data rates from 10 SPS to 1.5 MSPS and features built-in anti-aliasing of up to 102 dB. Since there is no need for a separate external anti-aliasing filter, the number of passive components can be reduced by 60 and active components by 5 in the design.

This device reduces board area by 70% compared to conventional alternative design implementations. The asynchronous sample rate converter simplifies the synchronization of multiple devices, making it easier for users to achieve coherent sampling systems and simplifying isolation requirements.

The AD7134, available in an 8mm × 8mm 56-pin LFCSP package, is currently in stock. The price is $17.85 per unit based on a 1,000-unit order.
