ADS7809P

The ADS7809P is designed as a complete 16-bit sampling analogto-digital using state-of-the-art CMOS structures. It contains a 16bit capacitor-based SAR A/D with S/H, reference, clock, and a serial data interface. Data can be output using the internal clock, or can be synchronized to an external data clock.

ADS7809P has twelve features. (1)100kHz sampling rate. (2)86dB sinad with 20kHz input. (3)+/-2LSB INL. (4)DNL: 16 bits no missing codes. (5)Six specified input ranges. (6)Serial output. (7)Single +5V supply operation. (8)Pin-compatible with 12-bit ADS7808. (9)Uses internal OR external reference. (10)100mW max power dissipation. (11)Sinple DSP interface. Those are all the main features.

Some absolute maximum ratings of ADS7809P have been concluded into several points as follow. (1)Its ground voltage differences: DGND, AGND2 would be +/-0.3V. (2)Its Vana would be 7V. (3)Its Vdig to Vana would be +0.3V. (4)Its digital inputs would be from -0.3V to Vdig+0.3V. (5)Its internal power dissipation would be 700mW. (6)Its maximum junction temperature would be +165°C. (7)Its lead temperature soldering 10s would be 300°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of ADS7809P are concluded into several points as follow. (1)Its resolution would be max 16bits. (2)Its voltage range would be +/-10V to 5V. (3)Its capacitance would be typ 35pF. (4)Its complete cycle would be max 10us. (5)Its input voltage low would be min -0.3V and max +0.8V. (6)Its input voltage high would be min +2.0V and max Vd+0.3V. (7)Its input current would be max +/-10uA. (8)Its output voltage low would be max +0.4V. (9)Its output voltage high would be min 4.0V. (10)Its leakage current would be max +/-5uA. (11)Its output capacitance would be max 15pF. And so on. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
