4 / 70 page  ADS42JB49 ADS42JB69 SLAS900C – OCTOBER 2012 – REVISED JULY 2013 www.ti.com ELECTRICAL CHARACTERISTICS: ADS42JB69 (16-Bit) Typical values are at TA = +25°C, AVDD = 1.8 V, AVDD3V = 3.3 V, DRVDD = 1.8 V, IOVDD = 1.8 V, 50% clock duty cycle, –1-dBFS differential analog input, and sampling rate = 250 MSPS, unless otherwise noted. Minimum and maximum values are across the full temperature range of TMIN = –40°C to TMAX = +85°C, AVDD = 1.8 V, AVDD3V = 3.3 V, DRVDD = 1.8 V, and IOVDD = 1.8 V. 2-VPP FULL-SCALE 2.5-VPP FULL-SCALE PARAMETER TEST CONDITIONS UNITS MIN TYP MAX MIN TYP MAX fIN = 10 MHz 74 75.9 dBFS fIN = 70 MHz 73.8 75.6 dBFS SNR Signal-to-noise ratio fIN = 170 MHz 70.8 73.3 74.7 dBFS fIN = 230 MHz 72.6 74 dBFS fIN = 10 MHz 73.9 75.7 dBFS fIN = 70 MHz 73.7 75.3 dBFS SINAD Signal-to-noise and distortion ratio fIN = 170 MHz 69.6 73.2 74.5 dBFS fIN = 230 MHz 72.2 73.1 dBFS fIN = 10 MHz 95 90 dBc Spurious-free dynamic range fIN = 70 MHz 91 88 dBc SFDR (including second and third fIN = 170 MHz 81 93 89 dBc harmonic distortion) fIN = 230 MHz 84 82 dBc fIN = 10 MHz 92 88 dBc fIN = 70 MHz 89 86 dBc THD Total harmonic distortion fIN = 170 MHz 78 91 86 dBc fIN = 230 MHz 82 80 dBc fIN = 10 MHz 95 95 dBc fIN = 70 MHz 91 88 dBc HD2 2nd-order harmonic distortion fIN = 170 MHz 81 93 94 dBc fIN = 230 MHz 84 82 dBc fIN = 10 MHz 95 90 dBc fIN = 70 MHz 96 93 dBc HD3 3rd-order harmonic distortion fIN = 170 MHz 81 94 89 dBc fIN = 230 MHz 86 84 dBc fIN = 10 MHz 102 102 dBc Worst spur fIN = 70 MHz 103 103 dBc (other than second and third fIN = 170 MHz 87 100 95 dBc harmonics) fIN = 230 MHz 99 93 dBc f1 = 46 MHz, f2 = 50 MHz, 97 95 dBFS each tone at –7 dBFS Two-tone intermodulation IMD distortion f1 = 185 MHz, f2 = 190 MHz, 90 89 dBFS each tone at –7 dBFS 20-MHz, full-scale signal on channel under observation; Crosstalk 100 100 dB 170-MHz, full-scale signal on other channel Recovery to within 1% (of full- Clock Input overload recovery scale) for 6-dB overload with sine- 1 1 cycle wave input For 50-mVPP signal on AVDD PSRR AC power-supply rejection ratio > 40 > 40 dB supply, up to 10 MHz ENOB Effective number of bits fIN = 170 MHz 11.9 12.1 LSBs DNL Differential nonlinearity fIN = 170 MHz ±0.6 ±0.6 LSBs INL Integrated nonlinearity fIN = 170 MHz ±3 ±8 ±3.5 LSBs 4 Submit Documentation Feedback Copyright © 2012–2013, Texas Instruments Incorporated Product Folder Links: ADS42JB49 ADS42JB69 |
