9 / 34 page ![]() VA AGND To Internal Circuitry I/O ADC10DL065 www.ti.com SNAS314B – JUNE 2006 – REVISED APRIL 2013 DC and Logic Electrical Characteristics (1) (2) (3) Unless otherwise specified, the following specifications apply for AGND = DGND = DR GND = 0V, VA = VD = +3.3V, VDR = +2.5V, PD = 0V, External VREF = +1.0V, fCLK = 65 MHz, fIN = 10 MHz, CL = 15 pF/pin, Duty Cycle Stabilizer On, parallel output mode. Boldface limits apply for TJ = TMIN to TMAX: all other limits TJ = 25°C Typical Limits Units Symbol Parameter Conditions (4) (4) (Limits) CLK, PD, OEA, OEB 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 1.0 V (max) IIN(1) Logical “1” Input Current VIN = 3.3V 10 µA IIN(0) Logical “0” Input Current VIN = 0V −10 µA CIN Digital Input Capacitance 5 pF DA0–DA11, DB0-DB11 DIGITAL OUTPUT CHARACTERISTICS VDR = 2.5V 2.3 V (min) VOUT(1) Logical “1” Output Voltage IOUT = −0.5 mA VDR = 3V 2.7 V (min) VOUT(0) Logical “0” Output Voltage IOUT = 1.6 mA, VDR = 3V 0.4 V (max) VOUT = 2.5V or 3.3V 100 nA IOZ TRI-STATE Output Current VOUT = 0V −100 nA +ISC Output Short Circuit Source Current VOUT = 0V −20 mA −ISC Output Short Circuit Sink Current VOUT = VDR 20 mA COUT Digital Output Capacitance 5 pF POWER SUPPLY CHARACTERISTICS PD Pin = DGND, VREF = VA 93.7 111 mA (max) IA Analog Supply Current PD Pin = VD 12 mA PD Pin = DGND 18.5 20.5 mA (max) ID Digital Supply Current PD Pin = VD , fCLK = 0 0 mA PD Pin = DGND, CL = 10 pF (5) 15 mA IDR Digital Output Supply Current PD Pin = VD, fCLK = 0 0 mA PD Pin = DGND, CL = 10 pF (6) 370 434 mW (max) Total Power Consumption PD Pin = VD 36 mW Rejection of Full-Scale Error with PSRR1 Power Supply Rejection Ratio 58 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 Note 3 under the Absolute Maximum Ratings. 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 ensure 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 10-bit LSB is 1.95 mV. (4) Typical figures are at TA = 25°C, and represent most likely parametric norms at the time of characterization. The typical specifications are not ensured. (5) IDR is the current consumed by the switching of the output drivers and is primarily determined by load capacitance on the output pins, the supply voltage, VDR, and the rate at which the outputs are switching (which is signal dependent). IDR=VDR(C0 x f0 + C1 x f1 +....C9 x f9) where VDR is the output driver power supply voltage, Cn is total capacitance on the output pin, and fn is the average frequency at which that pin is toggling. (6) Excludes IDR. See Note 5. Copyright © 2006–2013, Texas Instruments Incorporated Submit Documentation Feedback 9 Product Folder Links: ADC10DL065 |
