5MSPS, 16-Bit ADC is 2X Faster than Delta-Sigma Competition
Texas Instruments introduced the industryґs fastest 16-bit delta-sigma analog-to-digital converter (ADC) from the companyґs Burr-Brown product line. The ADS1605 features an industry-record 5MSPS (mega samples per second) data rate with outstanding high-speed performance: 88dB signal-to-noise ratio (SNR), -99dB total harmonic distortion (THD) and 101dB spurious-free dynamic range (SFDR).
The combination of high-speed and high-precision is ideal for demanding measurement requirements in scientific instrumentation, automated test equipment, data acquisition, medical imaging and vibration analysis.
The breakthrough speed and performance offered by the ADS1605 further illustrates TIґs leading data converter expertise and builds upon several recently released advanced data converters available from stock:
- ADS1605 - Industryґs fastest 16-bit delta-sigma converter (5MSPS)
- ADS8401 - Industryґs fastest 16-bit SAR converter (1.25 MSPS)
- ADS8383 - Industryґs first monolithic 18-bit SAR converter with no missing codes
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 directly connects to TIґs TMS320C6000TM DSP family. An out-of-range monitor reports when the input range has been exceeded.
The ADS1605 features a 2.45MHz input bandwidth (-3dB) and passband ripple less than +/-0.0025dB (to 2.2MHz). The device operates from a +5V analog supply and a +3V digital supply. The digital I/O supply operates from +2.7V to +5.25V, enabling the digital interface to support a range of logic families. Power dissipation is set by an external resistor and can be reduced when operating at slower speeds (315mW to 570mW). When not in use, the ADS1605 can be powered down with an I/O pin.
