Description

The ADS1278 evaluation module (EVM) is a platform for evaluating the performance of the ADS1278, which is a 24-bit, 8-channel simultaneous-sampling delta-sigma (ΔΣ) analog-to-digital converter (ADC). The ADS1278 combines high-precision industrial measurement with excellent dc and ac specifications, providing a usable signal bandwidth of up to 90% of the Nyquist rate with less than 0.005dB of passband ripple. The ADS1278 EVM eases the evaluation of the device with hardware, software, and computer connectivity through the universal serial bus (USB) interface.
