ADS1605

The ADS1605 is a high-speed, high-precision, deltasigma nalog-to-digital converter (ADC) with 16-bit resolution. The ata rate is 5MSPS, the bandwidth (3dB) is 2.45MHz, and assband ripple is less than ±0.0025dB (to 2.2MHz). The DS1605 offers outstanding performance at these speeds ith a signal-to-noise ratio up to 88dB, total harmonic istortion down to 99dB, and a spurious-free dynamic range p to 101dB.

The input signal is measured against a voltage reference that an be generated on-chip or supplied externally. The digital utput data is provided over a simple parallel interface that asily connects to DSPs. An out-of-range monitor reports hen the input range has been exceeded. The ADS1605 perates from a +5V analog supply (AVDD) and +3V digital upply (DVDD). The digital I/O supply (IOVDD) operates rom +2.7 to +5.25V, enabling the digital interface to support range of logic families. The analog power dissipation is set y an external resistor and can be reduced when operating t slower speeds. A power down mode, activated by a digital /O pin, shuts down all circuitry. The ADS1605 is offered in 64-pin TQFP package using TI PowerPAD technology.

The ADS1605, with its outstanding high-speed erformance is well suited for the demanding easurement requirements of scientific instrumentation, utomated test equipment, data acquisition, and medical maging.

The ADS1605 is designed as a high-speed, high-precision, deltasigma analog-to-digital converter (ADC) with 16-bit resolution. The data rate is 5MSPS, the bandwidth (3dB) is 2.45MHz, and passband ripple is less than ±0.0025dB (to 2.2MHz). The ADS1605 offers 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. Typical applications include scientific instruments, automated test equipment, data acquisition, medical imaging and vibration analysis.

ADS1605 has many features. The first one is data rate is 5MSPS. The second one is signal-to-noise ratio is 88dB. The third one is is total harmonic distortion is 99dB. The fourth one is spurious-free dynamic range is 101dB. The fifth one is linear phase with 2.45 MHz bandwidth. The sixth one is passband ripple is ±0.0025dB. The seventh one is selectable on-chip reference. The eighth one is directly connects to TMS320C6000 DSPs. The ninth one is adjustable power dissipation is from 315 to 570mW. The tenth one is power down mode. The eleventh one is supplies is analog +5V, digital +3V and digital I/O +2.7 to +5.25V. That are all the main features.

Some absolute maximum ratings of ADS1605 have been concluded into several points as follow. The first one is AVDD to AGND which would be from 0.3 to +6V. The second one is about its DVDD to DGND which would be from 0.3 to +3.6V. The third one is about its IOVDD to DGND which would be from 0.3 to +6V. The fourth one is about its AGND to DGND which would be from 0.3 to +0.3V. The fifth one is about its input current which would be 100mA, momentary. The sixth one is about its input current which would be 10mA, continuous. The seventh one is about its analog I/O to AGND which would be from 0.3 to AVDD + 0.3V. The eighth one is about its digital I/O to DGND whcih would be from 0.3 to IOVDD + 0.3V. The ninth one is about its maximum junction temperature which would be +150°C. The tenth one is operating temperature range which would be from 40 to +105°C. The eleventh one is storage temperature range which would be 60 to +150°C. The twelfth one is about its lead temperature (soldering, 10s) which would be +260°C. And so on. For more information about ADS1605, please contact us.
