The ADS1605 and ADS1606 are high-speed, high-precision, delta-sigma analog-to-digital converter (ADCs) with 16-bit resolution. The data rate is 5 mega-samples per second (MSPS), the bandwidth (–3dB) is 2.45MHz, and passband ripple is less than ±0.0025dB (to 2.2MHz). Both devices offer outstanding performance at these speeds with a signal-to-noise ratio up to 88dB, total harmonic distortion down to –99dB, and a spurious-free dynamic range up to 101dB. For even higher-speed operation, the data rate an be doubled to 10MSPS in 2X mode. The ADS1606 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.
