Texas Instru- ments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. ADS805E PARAMETER CONDITIONS MIN TYP MAX UNITS RESOLUTION 12 Bits Tested SPECIFIED TEMPERATURE RANGE –40 to +85 °C CONVERSION CHARACTERISTICS Sample Rate 10k 20M Samples/s Data Latency 6 Clk Cycles ANALOG INPUT Standard Single-Ended Input Range 1.5 3.5 V Optional Single-Ended Input Range 0 5 V Standard Common-Mode Voltage 2.5 V Standard Optional Common-Mode Voltage 1 V Input Capacitance 20 pF Analog Input Bandwidth –3dBFS Input 270 MHz DYNAMIC CHARACTERISTICS Differential Linearity Error (Largest Code Error) f = 500kHz ±0.25 ±0.75 LSB No Missing Codes Tested Spurious-Free Dynamic Range(1) f = 9.8MHz 65 74 dBFS(2) 2-Tone Intermodulation Distortion(3) f = 7.7MHz and 7.9MHz (–7dB each tone) –70 dBc Signal-to-Noise Ratio (SNR) f = 9.8MHz 63 68 dBFS Signal-to-(Noise + Distortion) (SINAD) f = 9.8MHz 62 66 dBFS Effective Number of Bits at 9.8MHz(4) 10.7 Bits Input Referred Noise 0V to 5V Input 0.09 LSBs rms 1.5V to 3.5V Input 0.23 LSBs rms Integral Nonlinearity Error f = 500kHz ±1 ±2LSB Aperture Delay Time 3ns Aperture Jitter 4 ps rms Over-Voltage Recovery Time 1.5x FS Input 2 ns Full-Scale Step Acquisition Time 20 ns ELECTRICAL CHARACTERISTICS At TA = full specified temperature range, VS = +5V, specified input range = 1.5V to 3.5V, and single-ended input and sampling rate = 20MHz, unless otherwise specified. NOTES: (1) Spurious-Free Dynamic Range refers to the magnitude of the largest harmonic. (2) dBFS means dB relative to full-scale. (3) 2-tone intermodulation distortion is referred to the largest fundamental tone. This number will be 6dB higher if it is referred to the magnitude of the 2-tone fundamental envelope. (4) Effective number of bits (ENOB) is defined by (SINAD – 1.76)/6.02. (5) Internal 50k Ω pull-down resistor. (6) Includes internal reference. (7) Excludes internal reference.
