6 / 28 page ADC084S051 SNAS261F – NOVEMBER 2004 – REVISED MARCH 2013 www.ti.com ADC104S051 Timing Specifications The following specifications apply for VA = +2.7V to 5.25V, GND = 0V, fSCLK = 3.2 MHz to 8 MHz, fSAMPLE = 200 to 500 ksps, CL = 50 pF, Boldface limits apply for TA = TMIN to TMAX: all other limits TA = 25°C. Limits Parameter Test Conditions Typical Units (1) VA = +3.0V −3.5 tCSU Setup Time SCLK High to CS Falling Edge See (2) 10 ns (min) VA = +5.0V −0.5 VA = +3.0V +4.5 tCLH Hold time SCLK Low to CS Falling Edge See (2) 10 ns (min) VA = +5.0V +1.5 VA = +3.0V +4 tEN Delay from CS Until DOUT active 30 ns (max) VA = +5.0V +2 VA = +3.0V +16.5 tACC Data Access Time after SCLK Falling Edge 30 ns (max) VA = +5.0V +15 tSU Data Setup Time Prior to SCLK Rising Edge +3 10 ns (min) tH Data Valid SCLK Hold Time +3 10 ns (min) tCH SCLK High Pulse Width 0.5 x tSCLK 0.3 x tSCLK ns (min) tCL SCLK Low Pulse Width 0.5 x tSCLK 0.3 x tSCLK ns (min) VA = +3.0V 1.7 Output Falling VA = +5.0V 1.2 tDIS CS Rising Edge to DOUT High-Impedance 20 ns (max) VA = +3.0V 1.0 Output Rising VA = +5.0V 1.0 (1) Tested limits are ensured to TI's AOQL (Average Outgoing Quality Level). (2) Clock may be either high or low when CS is asserted as long as setup and hold times tCSU and tCLH are strictly observed. 6 Submit Documentation Feedback Copyright © 2004–2013, Texas Instruments Incorporated Product Folder Links: ADC084S051 |
