7 / 26 page ADC10080 www.ti.com SNAS177H – JULY 2003 – REVISED MARCH 2013 DC AND LOGIC ELECTRICAL CHARACTERISTICS Unless otherwise specified, the following specifications apply for VSSA = VSSIO = 0V, VDDA = +3.0V, VDDIO = +2.5V, VIN = 2 VP-P, STBY = 0V, VREF = 1.20V (External), fCLK = 80 MHz, 50% Duty Cycle, CL = 10 pF/pin. Boldface limits apply for TA = TMIN to TMAX: all other limits TA = 25°C (1) (2) (3) Symbol Parameter Conditions Min Typ Max Units CLK, DF, STBY, SENSE Logical “1” Input Voltage 2 V Logical “0” Input Voltage 0.8 V Logical “1” Input Current +10 µA Logical “0” Input Current −10 µA D0–D9 OUTPUT CHARACTERISTICS Logical “1” Output Voltage IOUT = −0.5 mA VDDIO−0.2 V Logical “0” Output Voltage IOUT = 1.6 mA 0.4 V DYNAMIC CONVERTER CHARACTERISTICS(4) 9.3 9.5 Bits fIN = 10.0 MHz 9.1 ENOB Effective Number of Bits 9.3 9.5 Bits fIN = 39 MHz 8.9 58.5 59.5 dB fIN = 10.0 MHz 57.7 SNR Signal-to-Noise Ratio 58.0 59.2 dB fIN = 39 MHz 57.0 58.0 dB fIN = 10.0 MHz 59.2 56.3 SINAD Signal-to-Noise Ratio + Distortion 57.6 dB fIN = 39 MHz 59.0 55.6 −74.1 fIN = 10.0 MHz −87.0 dBc −68.7 2nd HD 2nd Harmonic −69.5 fIN = 39 MHz −82 dBc −62.7 −65 fIN = 10.0 MHz −72.3 dBc −58.6 3rd HD 3rd Harmonic −64.7 fIN = 39 MHz −74.5 dBc −57.6 −65 fIN = 10.0 MHz −72.3 dB −58.6 Total Harmonic Distortion (First 6 THD Harmonics) −64.7 fIN = 39 MHz −74.5 dB −57.6 −70.8 fIN = 10.0 MHz −78.7 dBc −68.2 Spurious Free Dynamic Range SFDR (Excluding 2nd and 3rd Harmonic) −72 fIN = 39 MHz −78.8 dBc −68 (1) To ensure accuracy, it is required that |VDDA–VDDIO| ≤ 100 mV and separate bypass capacitors are used at each power supply pin. (2) With the test condition for 2 VP-P differential input, the 10-bit LSB is 1.95 mV. (3) Typical figures are at TA = TJ = 25°C and represent most likely parametric norms. Test limits are ensured to AOQL (Average Outgoing Quality Level). (4) Optimum dynamic performance will be obtained by keeping the reference input at +1.2V.
