The component is suitable for DC to 350kHz applications and removes the need for an anti-alias filter, and its resistive input significantly simplifies ADC drive.
The AD7134 is a quad-channel, 24-bit precision ADC with output data rate scalable from 10SPS to 1.5MSPS. Inherent anti-aliasing up to 102 dB eliminates the need for an external anti-alias filter, thus requiring 60 fewer passive components and five fewer active components. It also saves 70% board area, relative to a typical alternative implementation.
Asynchronous sample-rate converter, simplifies multi-device synchronization, enables user to achieve coherent sampling system with ease, and simplifies isolation requirements.
Other specifications include:
THD: -120dB typical (ideal for AC, vibration or acoustic measurements)
108dB Dynamic Range (at ODR = 374kSPS)
Multiple Linear Phase Digital Filter Options (SINC6 for low latency, FIR for passband flatness)
Offset error drift: 0.7uV/°C typical
Gain drift: 2ppm/°C typical
