Boldface limits apply for TA = TJ = TMIN to TMAX: all other limits TA = TJ = 25°C (1)(2)(3) Units Symbol Parameter Conditions Typical (4) Limits (4) (Limits) VOUT(1) Logical “1” Output Voltage IOUT = −0.5 mA 2.7 V(min) VOUT(0) Logical “0” Output Voltage IOUT = 1.6 mA 0.4 V(max) VOUT = 3.3V 100 nA IOZ TRI-STATE Output Current VOUT = 0V −100 nA +ISC Output Short Circuit Source Current VOUT = 0V −20 mA(min) −ISC Output Short Circuit Sink Current VOUT = VDR 20 mA(min) POWER SUPPLY CHARACTERISTICS PD Pin = DGND, VREF = 1.0V 102 140 mA(max) IA Analog Supply Current PD Pin = VDR 4 mA PD Pin = DGND 5.3 7 mA(max) ID Digital Supply Current PD Pin = VDR, fCLK = 0 2 mA PD Pin = DGND, (5) <1 mA(max) IDR Digital Output Supply Current PD Pin = VDR, fCLK = 0 0 mA PD Pin = DGND, CL = 0 pF (6) 354 485 mW Total Power Consumption PD Pin = VDR, fCLK = 0 50 mW Rejection of Full-Scale Error with PSRR1 Power Supply Rejection 58 dB VA = 3.0V vs 3.6V SNR Degradation w/10 MHz, PSRR2 Power Supply Rejection −53 dB 250 mVP-P riding on VA DYNAMIC CONVERTER CHARACTERISTICS BW Full Power Bandwidth 0 dBFS Input, Output at −3 dB 170 MHz fIN = 1 MHz, Differential VIN = −0.5 dBFS 66 dB SNR Signal-to-Noise Ratio fIN = 10 MHz, Differential VIN = −0.5 dBFS 66 63.3 dB(min) fIN = 1 MHz, Differential VIN = −0.5 dBFS 65 dB SINAD Signal-to-Noise and Distortion fIN = 10 MHz, Differential VIN = −0.5 dBFS 65 62 dB fIN = 1 MHz, Differential VIN = −0.5 dBFS 10.6 Bits ENOB Effective Number of Bits fIN = 10 MHz, Differential VIN = −0.5 dBFS 10.3 10.0 Bits fIN = 1 MHz, Differential VIN = −0.5 dBFS −80 dB THD Total Hamonic Distortion fIN = 10 MHz, Differential VIN = −0.5 dBFS −74 −65 dB(max) fIN = 1 MHz, Differential VIN = −0.5 dBFS 82 dB SFDR Spurious Free Dynamic Range fIN = 10 MHz, Differential VIN = −0.5 dBFS 78 dB(min) fIN = 9.5 MHz and 10.5 MHz, each = −7 IMD Intermodulation Distortion −75 dBFS dBFS (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 +....C11 x f11) 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. 8 Submit Documentation Feedback Copyright © 2001–2013, Texas Instruments Incorporated Product Folder Links: ADC12L063 |
