4 / 15 page XRD87L75 4 Rev. 1.00 ELECTRICAL CHARACTERISTICS TABLE (CONT'D) UNLESS OTHERWISE SPECIFIED: AV DD = DVDD = 3.3V, FS = 6MHz (50% DUTY CYCLE), V RT = 2.5V, VRB = 0.5V, TA = 25°C 25°C Parameter Symbol Min Typ Max Units Test Conditions/Comments ACPARAMETERS Differential Gain Error d G 2 % FS = 4 x NTSC Differential Phase Error d PH 1 Degree FS = 4 x NTSC POWER SUPPLIES Operating Voltage (AV DD, DVDD) 9 V DD 3 3.3 3.6 V Current (AGND + DGND) I DD 8 12 mA Does not include ref. current NOTES 1. The difference between the measured and the ideal code width (V REF/256) is the DNL error (Figure 3). The INL error is the maximum distance (in LSBs) from the best fit line to any transition voltage (Figure 4). Accuracy is a function of the sampling rate (FS). 2. Guaranteed, not tested. 3. Specified values guarantee functionality. Refer to other parameters for accuracy. 4. –1dB bandwidth is a measure of performance of the A/D input stage (S/H + amplifier). Refer to other parameters for accuracy within the specified bandwidth. 5. See V IN input equivalent circuit (Figure 5). Switched capacitor analog input requires driver with low output resistance. 6. All inputs have diodes to DV DD and DGND. Input DC currents will not exceed specified limits for any input voltage between DGND and DVDD . 7. t R , tF should be limited to >5ns for best results. 8. Depends on the RC load connected to the output pin. 9. AGND & DGND pins are connected through the silicon substrate. Connect together at the package and to the analog ground plane. Specifications are subject to change without notice ABSOLUTE MAXIMUM RATINGS (T A = +25 °C unless otherwise noted)1, 2, 3 V DD to GND ....................................................... 5.5V V RT & V RB ......................... VDD +0.5 to GND –0.5V V IN ..................................... V DD +0.5 to GND –0.5V All Inputs ............................ V DD +0.5 to GND –0.5V All Outputs ......................... V DD +0.5 to GND –0.5V Storage Temperature .........................–65 to +150°C Lead Temperature (Soldering 10 seconds) ... +300°C Package Power Dissipation Rating @ 75°C PDIP, SOIC, SSOP .............................. 650mW Derates above 75°C ............................. 9mW/°C NOTES: 1. Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation at or above this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability. 2. Any input pin which can see a value outside the absolute maximum ratings should be protected by Schottky diode clamps (HP5082-2835) from input pin to the supplies. All inputs have protection diodes which will protect the device from short transients outside the supplies of less than 100 µA for less than 100ms. 3. V DD refers to AVDD and DVDD. GND refers to AGND and DGND. |
