8 / 33 page  VA AGND To Internal Circuitry I/O ADC12QS065 SNOSAD6H – JULY 2005 – REVISED MARCH 2007 www.ti.com DC and Logic Electrical Characteristics Unless otherwise specified, the following specifications apply for AGND = DGND = DRGND = 0V, VA = VD = +3.3V, VDR= +2.5V, External VREF = +1.0V, fCLK = 65 MHz, fIN = 5 MHz, CL = 15 pF/pin. Boldface limits apply for TJ = TMIN to TMAX: all other limits TJ = 25°C (1) (2) (3) (4) Units Symbol Parameter Conditions Typical(5) Limits(5) (Limits) DIGITAL INPUT CHARACTERISTICS VIN(1) Logical “1” Input Voltage VD = 3.6V 2.0 V (min) VIN(0) Logical “0” Input Voltage VD = 3.0V 0.5 V (max) IIN(1) Logical “1” Input Current VIN = 3.3V 1 µA IIN(0) Logical “0” Input Current VIN = 0V −1 µA POWER SUPPLY CHARACTERISTICS PD Pin = DGND 168 200 mA (max) IA Analog Supply Current PD Pin = VD 0.5 mA PD Pin = DGND 48 53 mA (max) ID Digital Supply Current PD Pin = VD 0.2 mA IDR LVDS Output Supply Current PD Pin = DGND, fIN = 33 MHz 46 62 mA (max) PWR Total Power Consumption PD Pin = DGND, CL = 5 pF 828 990 mW (max) (includes driver supply) PD Pin = VD 3 mW PSRR Rejection of Full-Scale Error with Power Supply Rejection Ratio 53 dB VA = 3.0V vs. 3.6V (1) The inputs are protected as shown below. Input voltage magnitudes above VA or below GND will not damage this device, provided current is limited per. However, errors in the A/D conversion can occur if the input goes above VA or below GND by more than 100 mV. As an example, if VA is +3.3V, the full-scale input voltage must be ≤+3.4V to ensure accurate conversions. (2) To guarantee accuracy, it is required that |VA–VD| ≤ 100 mV and separate bypass capacitors are used at each power supply pin. (3) With the test condition for VREF = +1.0V (2VP-P differential input), the 12-bit LSB is 488 µV. (4) When the input voltage at any pin exceeds the power supplies (that is, VIN < AGND, or VIN > VA), the current at that pin should be limited to 25 mA. The 50 mA maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input current of 25 mA to two. (5) Typical figures are at TA = 25°C, and represent most likely parametric norms at the time of product characterization. The typical specifications are not guaranteed. 8 Submit Documentation Feedback Copyright © 2005–2007, Texas Instruments Incorporated Product Folder Links: ADC12QS065 |
