ADS1605 ADS1606 SBAS274H − MARCH 2003 − REVISED MAY 2007 16-Bit, 5MSPS Analog-to-Digital Converter FEATURES DESCRIPTION D Data Rate: 5MSPS (10MSPS in 2X Mode) D Signal-to-Noise Ratio: 88dB D Total Harmonic Distortion: −99dB D Spurious-Free Dynamic Range: 101dB D Linear Phase with 2.45MHz Bandwidth D Passband Ripple: ±0.0025dB D Selectable On-Chip Reference D Directly Connects to TMS320C6000 DSPs D Easily Upgradable to 18 Bits with the ADS1625 and ADS1626 D Adjustable Power Dissipation: 315 to 570mW D Power Down Mode D Supplies: Analog +5V Digital +3V Digital I/O +2.7V to +5.25V APPLICATIONS D Scientific Instruments D Automated Test Equipment D Data Acquisition D Medical Imaging D Vibration Analysis The ADS1605 and ADS1606 are high-speed, high-precision, delta-sigma analog-to-digital converters (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 the same 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 can 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. The digital output data are provided ov...
