Dual 10-Bit, 105Msps, +3.3V, Low-Power ADC with Internal Reference and Parallel Outputs _______________________________________________________________________________________ 5 PARAMETER SYMBOL CONDITIONS MIN TYP MAX UNITS Operating, CL = 15pF , fINA or B = 20MHz at -0.5dB FS 15 mA Sleep mode 100 µA Output Supply Current IOVDD Shutdown, clock idle, PD = OE = OVDD 210 µA Operating, fINA or B = 20MHz at -0.5dB FS 413 511 mW Sleep mode 9.2 Power Dissipation PDISS Shutdown, clock idle, PD = OE = OVDD 350 µW Offset ±0.2 mV/V Power-Supply Rejection Ratio PSRR Gain ±0.1 %/V TIMING CHARACTERISTICS CLK Rise to Output Data Valid tDO Figure 3 (Note 3) 5 8 ns Output Enable Time tENABLE Figure 4 10 ns Output Disable Time tDISABLE Figure 4 1.5 ns CLK Pulse Width High tCH Figure 3, clock period: 9.5ns 4.75 ±1.5 ns CLK Pulse Width Low tCL Figure 3, clock period: 9.5ns 4.75 ±1.5 ns Wakeup from sleep mode (Note 4) 0.18 Wake-Up Time tWAKE Wakeup from shutdown (Note 4) 1.5 µs CHANNEL-TO-CHANNEL MATCHING Crosstalk fINA or B = 20MHz at -0.5dB FS -70 dB Gain Matching fINA or B = 20MHz at -0.5dB FS 0.02 ±0.2 dB Phase Matching fINA or B = 20MHz at -0.5dB FS 0.25 degrees ELECTRICAL CHARACTERISTICS (continued) (VDD = +3.3V, OVDD = +2.5V; 0.1µF and 1.0µF capacitors from REFP, REFN, and COM to GND; REFOUT connected to REFIN through a 10k Ω resistor, VIN = 2Vp-p (differential w.r.t. COM), CL = 10pF at digital outputs (Note 5), fCLK = 105.263MHz, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) Note 1: SNR, SINAD, THD, SFDR, and HD3 are based on an analog input voltage of -0.5dB FS, referenced to a +1.024V full-scale input voltage range. Note 2: Intermodulation distortion is the total power of the intermodulation products relative to the individual carrier. This number is 6dB or better, if referenced to the two-tone envelope. Note 3: Digital outputs settle to VIH, VIL. Parameter guaranteed by design. Note 4: With REFIN driven externally, REFP, COM, and REFN are left floating while powered down. Note 5: Equivalent dynamic performance is obtainable over full OVDD range with reduced CL. |
