The ADS1625 and ADS1626 are high-speed, high-precision, delta-sigma analog-to-digital converters (ADCs) with 18-bit resolution.
The ADS1625 and ADS1626 are high-speed, high-precision delta-sigma analog-to-digital converters (ADCs) with 18-bit resolution and a data rate of 1.25 mega samples per second (MSPS). These devices feature a bandwidth of 615kHz and offer outstanding performance metrics including a signal-to-noise ratio up to 93dB, total harmonic distortion down to -101dB, and a spurious-free dynamic range up to 103dB. The ADS1626 specifically includes an adjustable first-in, first-out (FIFO) buffer for output data.
