The ADS1625 and ADS1626 are high-speed, high-precision, delta-sigma analog-to-digital converters (ADCs) with 18-bit resolution. The data rate is 1.25 mega samples per second (MSPS), the bandwidth (-3dB) is 615kHz, and passband ripple is less than ±0.0025dB (to 550kHz). Both devices offer the same outstanding performance at these speeds with 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 includes an adjustable first-in, first-out buffer (FIFO) for the output data.
The input signal is measured against a voltage reference that can be generated on-chip or supplied externally. The digital output data is provided over a simple parallel interface that easily connects to digital signal processors (DSPs).
