Description

The ADS7806P is a low-power 12-bit sampling analogto-digital using state-of-the-art CMOS structures. It contains a complete 12-bit, capacitor-based, SAR A/D with S/H, clock, reference, and microprocessor interface with parallel and serial output drivers.

ADS7806P has eleven features. (1)35mW power dissipation. (2)50uW power down mode. (3)25us max acquisition and conversion. (4)+/-1/2LSB max INL and DNL. (5)72dB min SINAD with 1kHz input. (6)+/-10V, 0V to +5V and 0V to +4V input ranges. (7)Single +5V supply operation. (8)Parallel and serial data output. (9)Pin-compatible with 16-bit ADS7807. (10)Its Uses internal OR external reference. (11)28-pin 0.3'' plastic DIP and SOIC. Those are all the main features.

Some absolute maximum ratings of ADS7806P have been concluded into several points as follow. (1)Its ground voltage differences: DGND, AGND1 and 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 825mW. (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 ADS7806P are concluded into several points as follow. (1)Its resolution would be max 12bits. (2)Its voltage range would be +/-10V to 5V. (3)Its capacitance would be typ 35pF. (4)Its complete cycle would be max 20us. (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!
