2 / 30 page ADCS7476, ADCS7477, ADCS7478 SNAS192F – APRIL 2003 – REVISED MARCH 2013 www.ti.com PIN DESCRIPTIONS Pin No. Symbol Description ANALOG I/O 3 VIN Analog input. This signal can range from 0V to VDD. DIGITAL I/O Digital clock input. The range of frequencies for this input is 10 kHz to 20 MHz, with ensured 4 SCLK performance at 20 MHz. This clock directly controls the conversion and readout processes. 5 SDATA Digital data output. The output words are clocked out of this pin by the SCLK pin. 6 CS Chip select. A conversion process begins on the falling edge of CS. POWER SUPPLY Positive supply pin. These pins should be connected to a quiet +2.7V to +5.25V source and bypassed 1 VDD to GND with 0.1 µF and 1 µF monolithic capacitors located within 1 cm of the power pin. The ADCS7476/77/78 uses this power supply as a reference, so it should be thoroughly bypassed. 2 GND The ground return for the supply. Block Diagram These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. Absolute Maximum Ratings (1) (2) Supply Voltage VDD −0.3V to +6.5V Voltage on Any Analog Pin to GND −0.3V to VDD +0.3V Voltage on Any Digital Pin to GND -0.3V to 6.5V Input Current at Any Pin (3) ±10 mA ESD Susceptibility Human Body Model 3500V Machine Model 200V Soldering Temperature, Infrared, 10 seconds 215°C Junction Temperature +150°C Storage Temperature −65°C to +150°C (1) Absolute maximum ratings are limiting values, to be applied individually, and beyond which the serviceability of the circuit may be impaired. Functional operability under any of these conditions is not implied. Exposure to maximum ratings for extended periods may affect device reliability. (2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications. (3) Except power supply pins. 2 Submit Documentation Feedback Copyright © 2003–2013, Texas Instruments Incorporated Product Folder Links: ADCS7476 ADCS7477 ADCS7478 |
